A measurement system for estimating the depth of microvessels in skin tissue

Abstract

A measuring system for estimating skin tissue microvascular depth comprises a biological tissue sample information collection module, a light source module, a speckle imaging module, a precise reflection signal measuring module, a radiation reverse method analysis module and an evaluation and correction module. On the basis of these six modules, skin tissue sample information is collected to acquire a skin tissue model and tissue optical parameters; blood and vessel two-dimensional profile information of a focus microvessel is acquired through a speckle system, and the vascular diameter is acquired through image recognition; a high-accuracy reflection signal of a tissue sample is acquired through reflective signal measuring; the above three kinds of information is taken as input parametersto enter the radiation reverse method analysis module to acquire an estimated value of depth of the focus microvessel, and distribution laws of laser energy in skin tissue is evaluated; recommendation laser thermal therapy parameters are acquired by combining with blood information, and theoretical guidance is provided for improving clinical treatment effect on vascular dermatosis like port-winestain.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a measurement system for estimating the microvessel depth of skin tissue, which is mainly used in scientific research and clinical practice of laser hyperthermia for vascular skin diseases. Combining experimental measurement and theoretical inversion method to estimate the depth of microvessels in lesions, and provide theoretical guidance for evaluating and optimizing laser hyperthermia parameters. Background technique [0002] Vascular dermatosis generally refers to a class of skin diseases that originate in the microvessels of the dermis, such as port-wine stains, hemangiomas, and purpura. These diseases can lead to darkening of the skin tissue at the diseased site in mild cases, or lead to malignant deformities or distortions of local tissues in severe cases, or other complications, and even endanger the lives and health of patients. In many cases, the pathogenesis of vascular ...
