Abstract
The invention is applicable to the technical field of biological tissue imaging, and provides a tumor tissue imaging device and method. The tumor tissue imaging device comprises a light source, a polarizing part, a rotating wheel, a polarization analyzing part and a camera, wherein the light source, the polarizing part, the polarization analyzing part and the camera are distributed in a light pathdirection, and the rotating wheel is located between the polarizing part and the polarization analyzing part; and the rotating wheel is used for enabling the polarizing part or the polarization analyzing part to rotate according to a preset angle so as to switch imaging modes, and the imaging modes comprise reflection type imaging and transmission type imaging. Compared with an existing stainingtechnology, the requirement for pretreatment of tumor tissue to be detected is not high, the limitation on the size, the form and the light transmission of the tumor tissue to be measured is smaller,the measurement objects are wider, switching between the transmission type and reflection type can be freely realized, and the use flexibility and the applicability of the device are effectively improved.
Description
technical field [0001] The invention belongs to the technical field of polarization imaging, and in particular relates to a tumor tissue imaging device and method. Background technique [0002] The observation of tumor tissue in clinical practice generally adopts the form of stained section microscope observation. Part of the diseased tissue or organ needs to be taken, fixed and hardened after treatment, sectioned and stained, and the pathological changes are observed through an optical microscope, and the pathologist reads the slides Make a pathological diagnosis. Due to the different properties of tissues or cells, tissues with different components have different affinities to dyes, and different tissues have different color expressions after staining, so that pathologists can judge the pathological conditions of tumor tissues after staining. [0003] Polarization is one of the four inherent properties of light. Due to the insensitivity of human eyes to polarization, the ...
