Skin wound healing condition inspection system based on spectrum sub-band time domain autocorrelation

Abstract

The invention discloses a skin wound healing condition inspection system based on spectral sub-band time domain autocorrelation, and the system comprises an OCT imaging assembly which is used for simultaneously irradiating a skin wound of a sample arm and a reference arm for at least two times and enabling light returned from the reference arm to interfere with light returned from the sample arm, and obtaining at least two groups of spectral interference data; a spectrum sub-band data acquisition module which is used for intercepting the spectrum interference data to obtain spectrum sub-band data; a self-correlation function calculation module which is used for carrying out self-correlation function calculation on the at least two groups of spectral sub-band data in a time domain; and a healing condition identification module which is used for judging the healing condition of the skin wound on the sample arm according to the self-correlation result. According to the invention, the OCT has the capability of acquiring biological tissue depth information, the spectral sub-band data is extracted and dissected, the wound healing condition is examined, and the method has the characteristics of no contact, no radiation, no damage, high accuracy, strong applicability and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin wound healing inspection system based on spectral sub-band time-domain autocorrelation. Background technique [0002] Skin wounds, such as scratches on human arms and fingers, etc., how to judge and check the healing status of the wound, usually through the direct observation of the doctor's eyes and diagnostic experience to judge whether the wound has healed, mostly through the surface information of the skin Judge. The traditional inspection method, on the one hand, relies on the experience of the doctor, which is highly subjective, and its accuracy cannot be fully guaranteed. On the other hand, it cannot obtain the imaging information of the deep layer of the skin. At the same time, because there is no specific data to support it, it is impossible to quantify the degree of healing. Optical coherence tomography (OCT) uses the principle of low-coherence light interference...
