Laser-sonic Scanner Aims to Replace Mammograms for Finding Breast Cancer

06-18-18

A laser-sonic scanner, which uses photoacoustic computed tomography (PACT) developed by Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, can find tumors in as little as 15 seconds by shining pulses of light into the breast. The laser-sonic scanner provides a safer way for finding breast cancer compared to mammogram technology. Mammograms expose patients to X-ray radiation and requires their breasts to be painfully pressed between plates. Many women avoid having their mammograms taken as often as they should because of the discomfort involved. PACT can provide a clear view of structures as small as a quarter of a millimeter at a depth of 4 centimeters. Mammograms cannot provide soft-tissue contrast with the level of detail in PACT images. The PACT scan is quick, and a clearer image can be developed. [Caltech story]
