Patients using iPad to customize MRI scanning experience
As fans of the TV hospital drama House can tell you, many hospital patients aren't exactly fond of Magnetic Resonance Imaging (MRI) scanners. They're loud, confining, and generally quite uncomfortable. Now PDC Facilities, a company specializing in products for the medical diagnostics imaging market, has come up with a new product that uses an iPad to control and customize the patient experience. The product, known as the Caring MR Suite, lets patients "select personalized lighting, music, images and video to enjoy during their scan with a tap of the suite's iPad." If you're about to undergo a scan and would prefer to use your own music, images, and video, you can dock an iPhone or iPod for the ultimate in personalizing your way to a more comfortable experience. Special LED lighting fixtures and high-resolution displays are embedded in the walls and ceilings of the suite and controlled by the iPad. For a better idea of how the Caring MR Suite works to make scans a less frightening experience for patients, check out the video below.
Researcher brings modified Touchpad into the MRI room, breakthrough ensues
Yes, the Touchpad is officially dead, but that hasn't stopped Stanford researcher Andrew B. Holbrook from using HP's tablet in a somewhat unexpected setting: the MRI lab. Holbrook, it turns out, has been developing a new, webOS-based system that could make it a lot easier for doctors to conduct interventional MRI procedures. Unlike its diagnostic counterpart, this brand of MRI can only operate within highly magnetic fields, thereby posing a threat to many electronic devices. Holbrook, however, may have found a way around this barrier, thanks to a modified Touchpad. With the help of HP engineers, the researcher stripped his tablet of metallic components, including its speakers and vibration motor, resulting in what the manufacturer calls a "minimally metallic device that could be used almost anywhere within the magnet room." With his Touchpad primed and loaded with apps for data manipulation, Holbrook went on to successfully integrate the device within an MRI system. He also developed a series of apps that allow technicians to monitor and manipulate an MRI procedure on their devices, regardless of whether they're in the magnet room itself, or outside. Holbrook says he's already started applying the same approach to webOS phones, in the hopes of providing doctors and researchers with an even more compact way to keep track of their patients.

Scientists reconstruct images from our brains, plan to do the same for dreams (video)
This is your brain. And now this is your brain on YouTube. By using functional magnetic resonance imaging (fMRI) software, researchers at UC Berkeley created a visual representation of what our brains see when we watch a TV or movie. It works as such: scientists show subjects random clips and measure the corresponding cerebral activity. After the computer "learns" what vids evoke what brain activity, scientists feed 18 million seconds of random YouTube videos into the computer program where it reconstructs a movie representation of neural happenings based on the hundred clips most similar to what it sees. Although the method currently only works with images actually viewed, the future goal is to recreate what people see in their dreams and memories -- which could give doctors major insight to the minds of the mentally impaired, stroke victims or those with neurological disorders. Inception in real life isn't exactly around the corner, but the implications of this new technology are pretty mind-blowing. See for yourself in the video after the break -- no totem required.
BBC: Loving Apple looks like a religion to an MRI scan
Later today, BBC 3 will be airing Secrets of the Superbrands, a documentary about the relationship between consumers and the brands that shape our behavior, our desires and our lives. Series creator Alex Riley let slip an interesting tidbit in a preview post about the series: "The Bishop of Buckingham -- who reads his Bible on an iPad -- explained to me the similarities between Apple and a religion. And when a team of neuroscientists with an MRI scanner took a look inside the brain of an Apple fanatic it seemed the bishop was on to something. The results suggested that Apple was actually stimulating the same parts of the brain as religious imagery does in people of faith." Implying that Apple fandom equals zealotry may be attention-grabbing (and does indeed make me want to watch the program; too bad I can't use the BBC's iPlayer app here in the States), but the neurological similarity isn't surprising or particularly novel. You could almost certainly make the same observations about Red Sox fans, Twilight groupies, Van Halen lovers, Ducati collectors ... the list goes on, and whatever object of desire makes your heart pitter-patter will resonate in the neural patterns of your gray matter. Paraphrasing my colleague Chris Rawson, "This just in: the human brain is extremely susceptible to liking the things it likes to like. More details as we get them." As to whether there's something particularly intense, sustained or worshipful about the relationship between the Apple brand and Apple owners... well, seriously now, this question is appearing on The Unofficial Apple Weblog, one of thousands of sites, magazines, conferences and less-public obsessions dedicated to all things 'i' and the company that makes them real. Do you even have to ask? UPDATE: TUAW pal Alex Brooks from World of Apple let us know that it's his brain that's scanned on the program. Now I really want to see it! Thanks to Jörg for the tip.
Startup's headset will bathe your brain in ultrasound, might help fight cancer, too
The scientific community has spent a decade exploring ultrasound as a means of breaking through the blood-brain barrier -- a layer of tightly-packed cells that surround the brain's blood vessels, making it difficult for doctors to deliver chemotherapy and other treatments to cancer patients. Thus far, though, most ultrasound-based techniques have relied upon complex and often costly equipment, including MRI machines and infusion pumps. But researchers at a startup called Perfusion Technology think they may have come up with a less invasive, more cost-effective alternative -- a new headset designed to deliver low-intensity ultrasound therapy to the entire brain over the course of extended treatment periods. This approach differs markedly from most other methods, which typically target smaller areas of the brain with high-intensity ultrasound doses. As with most other potential breakthroughs, however, Perfusion's technique still needs to undergo some major testing. The company has already conducted several tests on animals, but the last time a similar method was tried on humans, many subjects ended up suffering from excessive bleeding. And that doesn't sound good at all.
Neurologists examine the brain on video games
The New York Times' Bits blogger Matt Richtel recently took part in a University of California at San Francisco study of the brain by playing a "primitive" racing game inside of an MRI machine. This wasn't one of those attempts to show that gaming can improve brain functions, but rather the early stages of a larger project to "measure and map the ethereal concept of attention." Ritchel's brain was observed as he maneuvered around or ignored "distractions" in the game (a multitasking simulation). Personally, we think this science project needs to evolve a bit. Look at that brain! It's bored out of its mind. For real, when there are other researchers out there bringing back giant aurochs from extinction or growing an "alien" form of bacteria, it's on today's scientists to step their game up. At least force test subjects to make some real Split/Second decisions. Following Richtel's playtime in the MRI scanner, Dr. Adam Gazzaley, lead researcher of the UCSF project, concluded that the results were "neither surprising nor novel and consistent with existing literature." Yeah, but what would happen if you threw in an attack helicopter and some exploding barrels? [Image sources: The New York Times; Shutterstock]
This is your brain. This is your brain on video games
Sure, you've probably seen countless scientific studies involving video games -- but have you have you ever wondered what your brain actually looked like while your playing video games? Well, feast your eyes on the image above. That's an MRI scan of New York Times writer Matt Richtel's brain that was captured while he played a simple driving game -- all in the name of science (and journalism), of course. As Richtel notes, however, that's just one example of the ways researchers are using such technology to "map the ethereal concept of attention," and scientists have turned up some other interesting findings as of late. Researchers at the University of Utah, for instance, have found that people's ability to juggle two tasks begins to drop off in their 30s and then sharply drops in their 40s, which contradicts earlier suspicions that people's ability to multitask only began to degrade when they're much older. Some other researchers are still suspicious of those findings, however, and Dr. Gazzaley of the University of California at San Diego is quick to point out that all of this research is still in the earliest stages -- he's expecting some more detailed findings next year when his team expands their tests and begin to incorporate EEG monitoring as well.
Neurosurgeons use MRI-guided lasers to 'cook' brain tumors
In the seemingly perpetual battle to rid this planet of cancer, a team of neurosurgeons from Washington University are using a new MRI-guided high-intensity laser probe to "cook" brain tumors that would otherwise be completely inoperable. According to Dr. Eric C. Leuthardt, this procedure "offers hope to certain patients who had few or no options before," with the laser baking the cancer cells deep within the brain while leaving the good tissue around it unmarred. The best part, however, is that this is already moving beyond the laboratory, with a pair of doctors at Barnes-Jewish Hospital using it successfully on a patient last month. Regrettably, just three hospitals at the moment are equipped with the Monteris AutoLITT device, but if we know anything about anything related to lasers, it'll be everywhere in no time flat.
Intel's mind reading computer could bring thought controlled interfaces to a whole new, frightening level
Thought controlled devices are pretty primitive at this point. Sure, everyone from Honda to the U.S. Army (of course) is conducting research, but at this point we don't have much to show for it all besides an evening of experimental music in Prague. If the kids at Intel have their way, computers will soon be able to look at a person's brain activity and determine actual words that they're thinking. The idea here is that the activity generated in the average person by individual words can be mapped and stored in a database, to be matched against that of someone using the thought control interface. So far, results have been promising -- an early prototype exists that can differentiate between words like screwdriver, house, and barn, by using a magnetic resonance scanner that measures something like 20,000 points in the brain. Anything more effective than that, such as dictating letters or searching Google with your mind alone is probably years in the future -- though when it does come to pass we expect to see a marked increase in expletive-filled liveblogs.
Scientists study how the brain thinks about virtual avatars
This is fascinating stuff to think about over the weekend -- New Scientist has an article (sent to us by quite a few readers -- thanks!) about how we perceive our virtual selves in video games like World of Warcraft. A group of scientists at Dartmouth University hooked a few WoW players up to an MRI recently, and they found that when asked to describe themselves and their virtual avatars, the same areas of the brain activated -- areas normally suited to "self-reflection and judgement." In other words, you think about your avatar the same way you think about yourself. They found nearly no difference in the way the brain activated when subjects considered themselves and their avatars. But when you make the split between virtual and real worlds (including your friends in both), the brain's center for imagination tends to light up whenever you consider the virtual world. You've got the normal parts of your brain working when thinking about yourself or others, but when you add in the virtual component, the imagination center lights up as well.
Tetris players found to have greater brain efficiency, thicker cortex and better hair
You just knew all that Tetris playing you did as a kid yesterday was good for you, huh? A new study published by the big thinkers at Mind Research Network has found that "practicing Tetris" can actually improve brain efficiency and lead to a thicker cortex in other areas of the tabula rasa. In short, the study was done in order to show that the brain can change with stimulation, and that "a challenging visuospatial task has an impact on the structure of the cortex." Of course, this is far from the first published report to use the quarter century-old title as its testing tool, but it's certainly one of the best for getting your mum and pop to believe gaming really is good for the gord. Hit up the read links below for all the details -- you know they'll be firing off questions when you hit 'em with this.[Image courtesy of BumpyBrains]Read - Tetris study [PDF]Read - Press release
Honda's ASIMO could be thought controlled in Spaceballs 2
Sorry, that's not actually Dark Helmet, it's a researcher demonstrating the latest Brain Machine Interface (BMI) cooked up for robotics. While it's not looking too portable, it's a far nimbler setup than the original MRI Scanner first concocted by Honda to control robots in near real-time back in 2006. This time, Honda Research Institute in coordination with Advanced Telecommunications Research (ATR) and Shimadzu Corporation have achieved robotic thought control using a sensor cap to measure electrical potential on the scalp and cerebral blood flow. While we've seen much of this BMI tech applied to video games in the past, Honda claims its technology achieves the world's highest accuracy at 90% without special training. Impressive, even though it's clearly R&D work for now. Check the video after the break. [Via Akihabara News]
IBM concocts microscope with ultra-fine resolution, current MRI bows down
The existing MRI has certainly been beneficial to humans everywhere, but IBM researchers are adamant on doing it one better. These gurus, working in tandem with the Center for Probing the Nanoscale at Stanford University, have demonstrated "magnetic resonance imaging (MRI) with volume resolution 100 million times finer than conventional MRI." What it's all mean? In short, it could give scientists the ability to investigate complex 3D structures at the nanoscale level, and according to IBM, it may "ultimately be powerful enough to unravel the structure and interactions of proteins." We know, only the nerdiest of you are amazed -- nay, affected whatsoever -- by that statement, but even the layperson can appreciate advanced methods of studying viruses, bacteria and other biological elements. A certifiably riveting demonstration vid awaits you beyond the break.[Via TG Daily, thanks Speedy]
French doctors use laser to destroy brain tumor in conscious patient
Neurosurgery with robotic assistance is getting pretty old hat nowadays, so it looks like scientists are trying to up the difficulty factor by keeping their patients awake -- a team of French doctors just completed the first successful removal of malignant brain tumor from a still-conscious patient, using a computerized laser and an MRI scanner to guide the probe. The fiber-optic laser was fed into the brain through a 3mm (.12 inch) hole in the patient's skull and guided via MRI to the tumor, where it fired for two minutes and completely destroyed the cancerous tissue. Once the tumor cells were dead, the cable was removed and the patient was allowed to return home -- all within a single day. That's pretty impressive, and it comes on the heels of 15 similar trials where five out six patients who underwent the total removal procedure were cancer-free nine months after surgery. The team says further research will cost an additional two million euros to progress, but if this technique works as well as they claim after peer review, we'd guess that money won't be hard to come by.[Via Fark]
Computer designed to read thoughts from brain scans
Frighteningly enough, this isn't the first (or second) time that we've seen scientists pat themselves on the back for creating a mind-reading machine, but a dedicated team from Carnegie Mellon has just announced a computer that "has been trained to read people's minds by looking at scans of their brains as they thought about specific words." In a completely unsurprising move, gurus familiar with the development are suggesting that the breakthrough could be used to better understand how the brain organizes knowledge, and eventually, treat language disorders and learning disabilities more effectively. That's all gravy from here, but when this stuff starts passing as evidence in court, you'll know it's time to seriously investigate a relocation to Mars.
Gaming graphics cards drive advances in medical imaging
We all know that gamers can actively help medical research through efforts like the PS3's Folding@Home project. Now comes word from UK's The Engineer magazine that gamers and their pumped up video cards are helping the cause of medical imaging without even trying.You see, speeding up the processing of magnetic resonance imaging is important to prevent the blurring effects of involuntary body movement. Networked supercomputers are fast enough to do it, but they're too expensive to be a wide scale solution. However, high-powered video cards, with their 128 built-in processors, provide the perfect, low-cost method for speeding things up. And why have those graphics cards so freaking cheap and powerful? "The reason for this is the games industry," said Kings College London Professor Tobias Schaeffter. "It is amazing how much the power of the cards increases annually by putting on more processors and more memory."So remember, the next time you plunk down hundreds of dollars for that new super-duper graphics card, you're not just helping your gaming experience -- in some small way, you're helping medical research.
Futuristic headband knows when you've had too much PC
For those who just can't call it quits, a team of researchers at Tufts University has developed a head adornment which can determine when you've been overly stressed, bored or simply numb to the world around you when using your computer. The crew is studying functional near-infrared spectroscopy (fNIRS) technology, which "uses light to monitor brain blood flow as a proxy for workload stress a user may experience when performing an increasingly difficult task." The band itself utilizes "laser diodes to send near-infrared light through the forehead at a relatively shallow depth," after which it can purportedly judge how intense one's workload is (or isn't). 'Course, we'd guess the most of us wouldn't need a machine to tell us that, eh?[Via InformationWeek]
iPhone assisting physicians
We've written about the iPod's popularity in the medical field, including Dr. Michael Barrett, who gave recordings of heart sounds to med students, and the digital stethoscope recording system for the iPod nano.While those things were cool, they're nothing compared to what's being done with the iPhone. A group called Heart Imaging Technologies ( or "HeartIT"*) has built a system that will allow a doctor to send or view a video of a patient's beating heart to an iPhone. Now that's cool.I'm not a physician, so these videos are nothing more that pulsing globs of grey to me, but they're pretty cool to watch. *Thank goodness they didn't choose "iHeart."[Via MacNN]
neuroArm gives surgeons extra dexterity, sense of touch
Considering that a BSOD within the robotic surgeon that's halfway through a critical operation on your innards is far from ideal, we're certainly in agreement with companies looking to make actual human doctors even better at their work. A team of Canadian scientists and engineers have concocted the neuroArm robot to allow doctors to perform microscopic operations on the brain in a more precise manner. Essentially, the uber-steady bot "will let doctors use surgical techniques on afflictions such as brain tumors that human surgeons are simply not dexterous enough to do," and when combined with a touchscreen stereoscopic viewer, it enables MDs to better visualize the area they're working with through advanced depth perception and "3D-like" imagery. The neuroArm system should hit clinical testing sometime within the next month or so, and if all goes smoothly (ahem), the long-term goal involves "manufacturing different versions" and selling them to a variety of hospitals.
Medical robot can do organ biopsies during MRI scans
The Johns Hopkins Urology Robotics Lab based in Baltimore, Maryland has developed a medical robot called the PneuStep that is capable of carrying out organ biopsies in the process of an MRI scan. The robot features a motor that provides power "without metal or electricity" which means that it can operate within the intense magnetic fields generated by Magnetic Resonance Imaging machines. Instead, it is made of "plastics, ceramics and rubber" and is "driven by light and air": specifically, a series of pistons and gears which are controlled by a computer in the next room. The motor also happens to be far more precise than the bags of meat that we usually trust to remove our tumors. The PneuStep could improve the treatment of prostate cancer, which is apparently in many cases impossible to spot outside of an MRI machine. Previously, surgeons relied on "blind" biopsies in the case of operations on organs like the prostate. We'd imagine then that the addition of this robot to a surgeon's tool box will do wonders for patient morale.[Via Medgadget]
