New detector made medical scans twice cheaper

Researchers from the U.S. and Japan have unveiled the first experimental cross-sectional medical scan,

which does not require tomography - a processimage reconstruction in CT/PET scans. The work, published in the journal Nature Photonics, could lead to cheaper, simpler and more accurate medical imaging.

According to Simon Cherry, professorBiomedical Engineering and Radiology of the University of California at Davis and the senior author of the paper, this progress was made possible by the development of new ultrafast photon detectors. “We get images at the speed of light, which was not possible before,” the scientists noted.

Before that, researchers could not restoreimage without tomographic reconstruction because the detectors were too slow. In the article, the researchers describe various tests they conducted using the new technique, including on a test object that mimics the human brain. They are confident that this procedure can ultimately be scaled up to the level required for clinical diagnosis, and has the potential to create higher quality images using a lower dose of radiation.

PET scans are now expensive andlimited technology. The new discovery will help create a compact installation that can be used to perform inexpensive, simple and accurate body scans using radioactive isotopes.
