A new X-ray-generating chip from Luis Velasquez-Garcia's group will reduce the radiation from medical imaging
Extremely Tiny X-ray: An electron-emitting chip is at the heart of a new type of X-ray source. It can replace large particle accelerators in phase-contrast imaging. Photo: Microsystems Technology Laboratories/MITThe X-ray that imaged your father's broken leg when he was a kid isn't fundamentally different from the one at your doctor's office today--other than that it's now digital rather than film-based. But the technology is on the verge of a big leap forward that will let doctors see more with less light.
