According to the invention, ultrasonic and opto-acoustic multi-mode high-resolution three-dimensional scanning imaging is carried out on the biological tissue to be detected by utilizing the ultrasonic transducer and the detection optical fiber through the three-dimensional moving mechanism, so that the problem of difficulty in real-time non-invasive monitoring and diagnosis of biological tissue diseases in the prior art is solved.
Description
technical field [0001] The invention relates to an ultrasonic and photoacoustic multi-mode high-resolution three-dimensional scanning imaging device. Background technique [0002] The structure of biological tissue is complex, and its main components are composed of non-organic matrix and organic matrix. When the tissue is pathologically affected, its physical structure characteristics will change, and its biochemical indicators will also change to varying degrees. Therefore, non-invasive acquisition of physical structure and biochemical index information of tissues for imaging, fusion analysis and early warning has very important clinical significance for early diagnosis and treatment of diseases. [0003] At present, medical institutions widely use X-ray-based CT scanning imaging method to diagnose the physical structure characteristics of bone tissue, mainly through imaging to characterize the bone tissue density as a diagnostic parameter, but this method cannot effectiv...
