Breast CT Team

The Boone Laboratory is located on the University of California Davis Medical Center campus in Sacramento. Mammography is the current standard for breast cancer screening, however it is acknowledged by experts in imaging that mammography is not ideal.  We are studying the potential of tomographic imaging of the breast using a custom-designed breast CT scanner. The breast CT system can generate 300 to 500 tomographic slices of the breast using the same radiation levels as two view screen film mammography, and these images allow the radiologist to view regions in the breast unobstructed by overlaying normal anatomical tissue, which can obscure lesion identification and reduce cancer detection performance, especially in the dense breast. We have designed, fabricated, and tested four prototype breast CT scanners in the lab, and were the first group in the world to perform cone beam breast CT on live women.
