Video game processors help lower CT scan radiation

imes faster than similar iterative reconstruction approaches, says Jia.

Compared to the currently widely used scanning protocol of about 360 projections with 0.4 mAs per projection, Jia says the new processing method resulted in 36 to 72 times less radiation exposure for patients.

"With our technique, we can reconstruct cone beam CT images with only a few projections -- 40 in most cases -- and lower mAs levels," he says. "This considerably lowered the radiation dose."

The reconstruction algorithm is part of the UCSD group's effort to develop a series of GPU-based low dose technologies for CT scans.

"In my mind, the most interesting and compelling possibilities of this technique are beyond cancer radiotherapy," says Steve Jiang, senior author of the study and a UCSD associate professor of radiation oncology.

"CT dose has become a major concern of medical community. For each year's use of today's scanning technology, the resulting cancers could cause about 14,500 deaths.

"Our work, when extended from cancer radiotherapy to general diagnostic imaging, may provide a unique solution to solve this problem by reducing the CT dose per scan by a factor of 10 or more," says Jiang.
