Abstract
The present invention discloses a photoacoustic endoscopic imaging component, a computer device and an endoscopic imaging method, wherein the component includes a photoacoustic endoscopic detection system and a photoacoustic endoscopic imaging system. The photoacoustic endoscopic detection system includes a balloon, a motion control unit and a photoacoustic endoscopic probe, and the photoacoustic endoscopic imaging system includes a synthetic aperture image data processing unit. When the photoacoustic endoscopic imaging component is imaging, the cavity of the balloon is filled with a liquid medium to support the inner wall of the organ to be measured, and the transducer focusing position receives the original data of the echo sound signal after the tissue excitation response in the balloon. The synthetic aperture image data processing unit uses the synthetic aperture principle to process the original data of the echo sound signal and the position and angle information of the transducer to obtain a high-resolution photoacoustic image. The present invention eliminates the influence of organ wrinkles and movement through balloon support, and uses the synthetic aperture principle to obtain a high-resolution photoacoustic image, thereby improving the accuracy of early diagnosis of digestive tract cancer.
