Precise 3D imaging makes it possible to track radiation, used to treat half of all cancer patients, in real time.
By capturing and amplifying tiny sound waves created when X-rays heat tissues in the body, medical professionals can map the radiation dose within the body, giving them new data to guide treatments. It’s a first-of-its-kind view of an interaction doctors have previously been unable to “see.”
“Once you start delivering radiation, the body is pretty much a black box,” says Xueding Wang, professor of biomedical engineering and professor of radiology who leads the Optical Imaging Laboratory at the University of Michigan.
“We don’t know exactly where the X-rays are hitting inside the body, and we don’t know how much radiation...
