We have integrated photoacoustic tomography into an automated breast ultrasound scanner. This system scans the patient in the prone position, so illuminating the breast required the development of a fiber-coupled illumination system and a light-shaping diffuser to direct the light onto the tissue. This system allows simultaneous acquisition of B-mode and multi-wavelength photoacoustic tomography data in a single, operator-independent scan. We present the first characterizations of this complete scanning system, as well as phantom data used to evaluate the attainable imaging depth, resolution, and sensitivity of the hardware and reconstruction scheme.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
