The system comprises a handheld optical imaging module, an ultrasonic imaging module, a mechanical closing mechanism, and a data processing module, wherein the mechanical closing module is used for packaging the whole imaging system and the data processing module; the handheld optical imaging module is used for optically imaging biological tissue under detection; the ultrasonic imaging module is used for carrying out 3-D ultrasonic imaging on the biological tissue under detection; the handheld optical imaging module and the ultrasonic imaging module share the high-performance data processing module and are used to control and coordinate imaging devices, acquire signals, reconstruct images and register fusion; the advantages of optical imaging mode and those of 3-D ultrasonic imaging mode can be combined to more comprehensively reflect structural and physiological function information.

Description

technical field [0001] The invention relates to the technical field of multimodal biomedical imaging, in particular to a multimodal fusion imaging system and method for handheld ultrasonic imaging and optical imaging. Background technique [0002] Thanks to the continuous progress of optical molecular probes and imaging methods, optical molecular imaging technology has achieved rapid development in the past ten years, and has been widely recognized for its high sensitivity, high specificity, no ionizing radiation, and low cost. More and more attention. Optical molecular probe technology makes it possible to distinguish normal tissues from interested tissues (such as tumors, blood vessels, etc.) with high specificity. How to detect the distribution of molecular probes in organisms with high sensitivity and reflect the physiological and pathological information of organisms is an important issue in imaging research. Due to the strong absorption and scattering of photons by b...
