[0046] Based on the endoscopic fluorescence ultrasound fusion imaging navigation system of Embodiment 1, the endoscopic fluorescence ultrasound fusion imaging navigation system of the present invention can extend into the living body for endoscopic detection and provide imaging navigation during the operation process. Preferably, The working method and working parameters of the endoscopic fluorescent ultrasound fusion imaging navigation system of the present invention are:

[0047] S1. The multi-spectral light source irradiator provides light source and energy for fluorescence imaging. The multi-spectral laser emitter is a two-spectrum laser emitter of visible white light and near-infrared laser. Preferably, the wavelength of visible white light is 400nm-650nm, and the wavelength of near-infrared laser is 400nm-650nm. The wavelength of the laser is 760nm, and the multispectral laser transmitter can excite the diseased tissue to emit near-infrared fluorescence with a wavelength of...

Embodiment 3

[0056] Based on the working method of the endoscopic fluorescent ultrasound fusion imaging navigation system in Embodiment 2, preferably, the processing method of the fluorescent image by the information processing module is:

[0057] S11. The multi-spectral laser transmitter emits visible white light and near-infrared laser and irradiates the biological tissue through the multi-spectral light source irradiator. Due to the different molecular forms of the biological tissue, a specific fluorescent contrast agent will be formed around the diseased tissue Polymerization layer, under the excitation of a specific near-infrared laser, the fluorescence brightness is outstanding, and the largest point in the fluorescence image can be regarded as a diseased tissue; the endoscopic detector module captures the fluorescence image at this time in real time and transmits it to the information processing module;

[0058] S12. The information processing module greatly improves the contrast and...

Abstract

The invention discloses an endoscopic fluorescent ultrasonic fusion radiography navigation system which comprises a multi-spectral light source, a high-frequency ultrasonic excitation module, an endoscopic detector module and an information processing module. The endoscopic detector module comprises an ultrasonic probe and an optical probe, the optical probe is used for irradiating tissues of openorganisms to obtain fluorescence images of specific tissue positions and transmitting the fluorescence images to information processing module, the high-frequency ultrasonic excitation module is usedfor transmitting multi-frequency ultrasonic, the ultrasonic probe is used for ultrasonically detecting pathological tissues to obtain continuous two-dimensional ultrasonic images of the pathologicaltissues and transmitting the continuous two-dimensional ultrasonic images to the information processing module, and the information processing module performs 3D (3- dimensional) registration and fusion on the continuous two-dimensional ultrasonic images to obtain 3D ultrasonic images of the pathological tissues. According to the system, whole probing of the pathological tissues or tumors can be achieved by the aid of fluorescent ultrasonic fusion radiography, and clinical application requirements are met.

Description

technical field [0001] The invention relates to the field of multimodal medical imaging, in particular to an endoscopic fluorescent ultrasound fusion imaging navigation system. Background technique [0002] The endoscopic navigation system is used in endoscopic surgery, which refers to a small endoscopic device used by doctors to enter the interior of the living body through a minimally invasive channel during the operation, and the intraoperative navigation is completed by detecting the interior of the living body. Due to its advantages of minimal trauma and easy recovery, endoscopic surgery holds a large proportion of surgical operations. [0003] The endoscopic navigation system based on optical fluorescence imaging has been seen in clinical applications. The specific fluorescence imaging method obtained by exciting tissue with laser can effectively judge the outline of tumor or diseased tissue. Although the optical fluorescence imaging navigation system provides guidanc...
