Abstract

The present invention relates to a sensor, an imaging system and an imaging method applied to optical coherent elastography, comprising: a rigid part, an installation hole is opened inside the rigid part; a light-transmitting part, the light-transmitting part is located in the installation hole Inside: an elastic connecting piece, which is arranged between the light-transmitting piece and the rigid piece; wherein, a pressing portion protrudes from the light-transmitting piece, and the pressing portion is higher than the elastic connecting piece and a light-transmitting member; when the pressing portion presses against the sample, the elastic connecting member deforms to displace the light-transmitting member, and obtains the mechanical properties of the sample by collecting the optical characteristic change of the light emitted by the light-transmitting member. It can realize the integration of elastic modulus quantitative analysis and imaging, has good imaging effect, is convenient for elastic modulus analysis, and is convenient and convenient.

Description

technical field [0001] The invention relates to the technical field of optical coherent elastography, in particular to a sensor, an imaging system and an imaging method applied to optical coherent elastography. Background technique [0002] Optical coherence elastography (OCE) is a new type of biomedical elastography technology, which uses optical coherence tomography (OCT) equipment to detect the deformation response of tissues along the depth direction after being loaded, and to Elastic parameters such as Young's modulus, stress and strain of the tissue are the imaging objects. Compared with the more mature ultrasonic elastography and magnetic resonance elastography, OCE not only has the advantages of production cost, but also maintains the advantages of high resolution and non-invasiveness of OCT, and can provide much higher than ultrasonic elastography and magnetic resonance elastography. The imaging resolution and mechanical sensitivity of imaging, in terms of acquisit...
