  • Photoacoustic probe
    Patent number: 10863967
    Abstract: Disclosed herein is a photoacoustic tomography (PAT) probe to direct light to various regions within the tissue of interest to improve image quality and remove cumbersome artifacts at their source. Particularly, a rotating PAT probe and method of using thereof to improve the photoacoustic penetration depth and signal to noise ratio in biological samples. Signal intensity at region of interest is increased by fine-tuning the fiber orientation with respect to the ultrasound transducer. Additional PA filter is used to prevent in vivo probe-skin artifacts.
    Type: Grant
