Near-infrared spectrum imaging system and near-infrared spectrum imaging method for diagnosis of depth and area of burn skin necrosis

Abstract

The invention provides a near-infrared spectrum imaging system for diagnosis of depth and area of burn skin necrosis. The near-infrared spectrum imaging system comprises a spectrum imager and a computer-control system. The spectrum imager acquires 1100-2500nm waveband spectral signals of burn skin necrosis tissue of a target area, the spectral signals are subjected to image analyzing and processing through the computer-control system, the depth and area of burn of the target area can be acquired through spectral matching recognition upon a spectral reflectance curve corresponding to each image element in spectral images and a standard spectral reflectance curve in a burn skin necrosis spectral database in a data module and are synthesized into three-dimensional image display of the target area. By the near-infrared spectrum imaging system, the spatial structure of skin changed due to tissue protein denaturation before and after the skin burn can be specified, so that micron-level information about boundaries of normal skin tissue and necrotic tissue and the depth of burn skin necrosis can be provided visually, and clinical diagnosis, treatment and prognosis judgment can be supportively facilitated.

Description

technical field [0001] The invention relates to the technical fields of tissue damage and spectral imaging. Background technique [0002] Burns are common diseases both in peacetime and in wartime, especially in wartime. The mortality rate, disfigurement rate, and disability rate after burns are high, and the treatment cycle is long, which directly threatens life safety and body health, and brings a heavy burden to society and families. [0003] At present, the accurate judgment of the degree of skin tissue damage caused by burns is still a major problem in burn surgery, but the most common clinical method for the diagnosis of burn depth still mainly relies on clinical experience, including observing the appearance of burn wounds, capillary refilling, etc. condition and wound sensation to touch and needle prick pain, etc. Statistics show that the best burn doctors in the world only have an accuracy rate of about 70% for empirical diagnosis of wounds, that is, at least 30% ...

AI Technical Summary

Problems solved by technology

[0013] Therefore, so far, there is no diagnostic instrument and related method that can directly and accurately distinguish the depth of necrotic tissue, and accurately distinguish the boundary between necrotic tissue and normal tissue.
