Miniscule device gets injected into tumors, tracks radiation dosage
Gurus at Purdue University have conjured up a prototype device which, when injected into a tumor, can actually track the "precise dose of radiation received and locate the exact position [of the tumor] during treatment." Currently, the needle-sized device is held within a hermetically sealed glass capillary, contains a miniature radiation dosimeter, operates without batteries and instead relies on "electrical coils placed next to the patient" for activation. As small as the RFID-enabled unit is, engineers are still hoping to create a version that is around the size of a grain of rice, and hopes are to have it in clinical trials in 2010.

I dont get it, could somebody explain this to me?
if you could place it in a tumor, doesnt that mean you already know the position of the tumor?
Yes and no. Placement is a gross position thing; you simply use a radiography guided needle to place the probe in roughly the center of the tumor. The positioning comes into play when actual radiotherapy is used. It relays positional information (similar to GPS theory) back to the computers, allowing for precision use of radiation.
To add to what Tyler said- imagine the tumor is in front of your heart. Radiation therapy takes awhile, and every heartbeat and breath moves the tumor, so you have to balance missing the tumor with zapping your heart. Having a target like this sensor gives you something akin to image stabilization, or laser-guided missiles. At least that's how I understand it.
What's that? You're a douchebag? Don't worry we already know.
GOOOOODDDDDDD DAMMMMMNNNNIITTTTTT.
:S What are you guys talking about I thought it was really interesting what happened to the tumor!!
What a loser! You stink Mr. McDonald... you and your fast food!
its MAC donald spelled with a SMALL d, THANK YOU VERY MUCH!!!!!
Everyone on teh internetz is so pissy. Look McDonald - chillax for 5 minutes.... and then make your mind up - do you want to want to have a farm or do you want to get your bitcha ass back in the kitchen and get me a Big Mac, fries and a coke?
Thats right. If you're on the internet - you WILL get the piss taken out of you. (Hence, lighten up. life's too short. Unless you're immortal like Christopher Lambert. Although he would die if his head was cut off. Train of thought now crashing...)
Psh! Whatever MAC
I always have JavaScript disabled unless I know the site needs it...
Your rickroll is fail. (Just like this comment)
actually you sort of fail for having to turn on javascript all the time
Yeah, comment failed as expected... damn comment system :-P
Actually - no. You'd be surprised of how much websites work perfectly with JS and plug-ins disabled (the difference is actually quite pleasurable: instead of ads you only see gray squares :D )
omg they deleted it!!
Yes, they deleted it indeed....
You're 100% pwnt. (And I feel your pain, now my comment is floating free on the cyberspace totally unrelated to the rest of the comments..)
go boilers
boiler up!
how do i change my user pic from this default one? Where's the log in for members? Someone tell me pls
Click on your name in the post above, which will take you to your profile page. Then click on where it says "Login Here" and then enter your password. That's it.
IT'S NOT A TUMOR!
Thank you, I thought I'd have to do that...
Arnie needs to come out with another movie soon, I forget he exists sometimes.
he's still honing his acting skills in Sacramento, haventcha heard?
this "accomplishment" pales in comparison to that of the other true and noble gurus at purdue. go burger makers!
put it in your head and test cell phone usage
If only my dad could get one of these right now...he's got Pancreatic Cancer. :\
