Dual Scan Photoacoustic Mammoscope

Use light to listen for breast cancer. As strange as it sounds ultrasound images can be generated using light. In photoacoustic imaging tissue is heated by exposure to light from a fast-pulse laser. The thermal elastic expansion of the tissue creates an acoustic wave which can be detected and imaged by a ultrasonic transducer. The process eliminates...
