Ultrasonic and photoacoustic multi-mode real-time imaging device

Abstract

The invention provides an ultrasonic and photoacoustic multi-mode real-time imaging device, which is characterized by comprising an imaging probe and an imaging analysis device; the imaging probe comprises an ultrasonic transducer and a laser beam expander; and the imaging analysis device comprises a cooperative processing module, a signal acquisition module, an optical signal modulation module, an ultrasonic beam forming module, an image reconstruction module, a light source module and an optical lens module. The light source module and the optical signal modulation module generate modulated laser and transmit the modulated laser to the laser beam expander. The laser beam expander is used for expanding the modulated laser to irradiate the modulated laser on biological tissue to be detected and acquiring an acoustic-optical signal to obtain a first electric signal. The ultrasonic beam forming module emits ultrasonic waves and outputs the ultrasonic waves to the biological tissue to be detected. The ultrasonic transducer acquires the reflected ultrasonic signal and forms a second electrical signal. The cooperative processing module analyzes and processes the first electric signal and the second electric signal to obtain multi-mode data. The image reconstruction module carries out real-time image reconstruction and image fusion analysis on the multi-mode data.

Description

technical field [0001] The invention relates to a multimodal real-time imaging device of ultrasound and photoacoustics. Background technique [0002] Early diagnosis of diseases in the human motor system is crucial to the health of the population. The musculoskeletal and other tissue structures in the motor system are complex, and its main components are composed of non-organic matrix (mostly minerals) and organic matrix. The non-organic matrix mainly includes calcium hydroxyapatite, phosphate, and water; the organic matrix mainly includes collagen, hemoglobin, and lipids. The above-mentioned components are distributed in complex tissues to maintain human body movement. When the tissues in the movement system become diseased, their physical structure characteristics will change, and biochemical indicators will also change to varying degrees. Therefore, non-invasive acquisition of physical structure and biochemical index information of tissues for imaging, analysis and early...
