Horses are majestic creatures, but one thing they are not is tiny. Well, not for long, anyway. That creates a problem for equine medicine. When an animal weighs just under an imperial ton and is six-foot tall at the shoulders, there's only so much a veterinarian can do while the animal is still conscious. To that end, the University of Pennsylvania School of Veterinary Medicine (phew) is partnering with imaging outfit 4DDI to make free-standing CT scans a reality. Dubbed "Equimagine," the setup uses a pair of robotic arms that can gather internal images of a horse while it's awake and standing on all fours.
