An advanced photoacoustic tomography system providing high-resolution, 360-degree imaging without tissue compression for improved breast cancer screening.
Technology Summary
This technology features an all-reflective optical system that converts collimated light into a converging ring-shaped beam, enabling circumferential illumination of tissue for precise photoacoustic imaging. Incorporating a sequence of specialized mirrors and a ring-shaped acoustic detector, it captures ultrasonic signals efficiently while scanning layer-by-layer along the subject’s axis. The system adapts laser intensity automatically based on real-time distance measurements to ensure uniform energy delivery. Its fully enclosed reflective design eliminates chromatic aberrations, offering faster, deeper, and more uniform imaging compared to traditional methods.
