Embodiment 1

[0085] figure 1 A flow chart of a positioning method for in-situ visualization of a biological target in this embodiment is given. Such as figure 1 As shown, the in-situ visible positioning method of the biological target in this embodiment includes:

[0086] S101: Collect the fluorescence emitted by the fluorophore of the biological target in real time to form a fluorescent image of the biological target.

[0087] In step S101, the fluorophore of the biological target is an intrinsic fluorophore of the biological target or an exogenous fluorophore received by the biological target.

[0088] When the fluorescent group of the biological target is the inherent fluorescent group of the biological target, the fluorescence emitted by the fluorescent group of the biological target is: the fluorescence formed spontaneously by the inherent fluorescent group of the biological target or the inherent fluorescent group of the biological target by an external light source Fluorescence p...

[0132] Figure 4 A schematic diagram of the principles of a positioning system for in-situ visualization of biological targets in this embodiment is given.

[0133] The positioning system for in-situ visualization of biological targets in this embodiment includes an imaging system, an image processing and analysis unit, an image positioning and projection unit, and a beam splitter.

[0134] This embodiment provides a positioning system for in-situ visualization of biological targets, including:

[0135] (1) An imaging system, which is used to collect the fluorescence emitted by the fluorescent group of the biological target in real time, so as to form a fluorescent image of the biological target.

[0136] The fluorophore of the biological target is the intrinsic fluorophore of the biological target or the exogenous fluorophore received by the biological target.

[0137] When the fluorescent group of the biological target is the inherent fluorescent group of the biological ta...

[0177] Such as Figure 6 As shown, the in-situ visible positioning system for biological targets in this embodiment includes an imaging system, an image positioning and projection unit, an image processing and analysis unit, an excitation light source, a supplementary light source and a spectroscope. Moreover, the imaging system, image positioning and projection unit, image processing and analysis unit and a spectroscope are integrated into a core whole to form a complete positioning device. The imaging system, image positioning and projection unit, image processing and analysis unit and a beam splitter are all arranged inside the positioning device. The positioning device is also provided with a window for the transmission of the fluorescent light and the projection beam.

[0178] In this embodiment, the optical path from the biological target to the lens in the image positioning projection unit is set as the first optical path, the optical path from the biological target to...

Abstract

The invention belongs to the field of biological target positioning. In order to solve the problems that the boundary of a biological target cannot be accurately recognized and the biological target cannot be subjected to in-situ labeling, the invention provides a biological target in-situ visual positioning method and system, which can be used for efficiently and accurately positioning, identifying, protecting and judging the boundary of the biological target in real time within the visual field range of naked eyes. The biological target in-situ visual positioning method comprises the following steps: collecting fluorescence emitted by a fluorophore of a biological target in real time so as to form a fluorescence image of the biological target; processing the fluorescence image of the biological target to obtain an image, which only contains the biological target and has a clear boundary; adjusting the light path of a projection light beam projected to the biological target to be coaxial with the light path of fluorescence emitted by the biological target, and projecting the image, which only contains the biological target and has a clear boundary, to a biological target area emitting fluorescence in-situ in real time in an equal proportion manner.

Description

technical field [0001] The invention belongs to the field of high-end medical optical instruments, and in particular relates to a positioning method and system for in-situ visualization of biological targets. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the field of biomedicine, some normal or diseased biological targets (such as tumors, microorganisms, lymph nodes, soft tissue sarcomas, or other tissues or organs) are integrated with the surrounding environment, and professionals cannot accurately determine the location of biological targets, even if they judge Knowing its location, it is also difficult to judge its complete shape and precise boundary. This creates difficulties for the later operations of biological targets (such as in situ protection, in situ removal, surgical resection or puncture, etc.), and it is impossible to ...
