Handheld Gamma Ray Camera to Guide Surgery
We have built a compact, high sensitivity, high resolution gamma ray imaging system, that requires only 1 second to collect and form useful images for decision making during surgical procedures. The system is currently used twice a week by surgical oncologists in image-guided melanoma and breast cancer staging procedures. We have plans to improve the camera technology to enable it to determine the depth of structures of interest, such as lymph nodes that drain a tumor basin, and expand its clinical evaluation in image-guided procedures. Other camera technologies have been studied in our group for a number of years.
