Embodiment Construction

[0049]The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0050] refer to figure 1 As shown, the present invention discloses a sensor 10 applied to optical coherent elastography, including a rigid part 11 , a light-transmitting part 12 and an elastic connecting part 13 . An installation hole is opened inside the rigid member 11 . The light-transmitting member 12 is located in the installation hole. The elastic connecting part 13 is disposed between the transparent part and the rigid part 11 . Wherein, a pressing portion protrudes from the transparent member 12, and the pressing portion is higher than the elastic connecting member 13 and the transparent member 12. When the pressing portion presses against the sample, the elastic connect...

Abstract

The invention relates to a sensor, an imaging system and an imaging method applied to optical coherence elastography, and the sensor comprises a rigid piece which is internally provided with a mounting hole in a penetrating manner; a light transmitting piece is positioned in the mounting hole; an elastic connecting piece is arranged between the light transmitting part and the rigid piece; wherein an abutting part is arranged on the light transmitting piece in a protruding manner, and the abutting part is higher than the elastic connecting piece and the light transmitting piece; and when the abutting part abuts against the sample, the elastic connecting piece deforms to enable the light-transmitting piece to move, and the mechanical characteristics of the sample are obtained by collecting the optical characteristic change of the light emitted by the light transmitting piece. The sensor can realize integration of elastic modulus quantitative analysis and imaging, is good in imaging effect, facilitates elastic modulus analysis, and is convenient and fast.

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...
