Near-infrared breast scanning imaging method and related components

Abstract

The invention discloses a near-infrared breast scanning imaging method. The method comprises the following steps of: performing bidirectional scanning on a breast through a bidirectional detector, obtaining two groups of transmission data based on the bidirectional scanning, modeling voxels of a cross-sectional layer with a specified height in a space where the breast is located based on the two groups of transmission data respectively, obtaining two sets of optical propagation equations containing unknown numbers of breast heights, wherein the two sets of equations are simultaneous to form a positive definite equation set, the number of the equations is greater than the number of the unknown numbers, and the two sets of equations are simultaneous to solve an optical coefficient to determine a value corresponding to each delimited height, thereby obtaining a real cross-sectional imaging value. Therefore, the method can support optical reconstruction of breast internal points at different heights overlapped on a plane projection point of the same detector, and realize real three-dimensional reconstruction. The invention also discloses a near-infrared breast scanning imaging device, equipment, a system and a readable storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a near-infrared breast scanning imaging method, device, equipment, system and readable storage medium. Background technique [0002] With the development of physical optics and the continuous improvement of the mathematical model of light propagation in tissue, Diffuse Optical Tomography (DOT, Diffuse Optical Tomography) has made it possible to perform targeted fluoroscopic imaging of cancerous breast tissue. The technology uses light in the non-ionizing near-infrared range (wavelengths from 700 to 1,200nm) to create images of the breast in less than 30 seconds by simply placing the image pad on the breast under pressure. Optical scanning is carried out inside. Optical imaging methods offer the potential to distinguish soft tissues that are otherwise indistinguishable, and specific absorption of natural chromophores (such as hemoglobin) can also provide biologic...

Problems solved by technology

However, whether it is two-dimensional or pseudo-three-dimensional, it cannot truly reflect the optical properties of three-dimensional tissue, cannot obtain details at any height inside the breast, and cannot determine the optical absorption status at any height inside the breast.
