ASSESSING PERIPHERAL VASCULAR DISEASE FROM A THERMAL IMAGE
First Claim
1. A method for assessing peripheral vascular disease from a thermal image, the method comprising:
- receiving a thermal image of an area of exposed skin of at least one peripheral body part of a subject of interest being monitored for peripheral vascular disease, said thermal image being acquired by a thermal imaging system, said thermal image comprising a plurality of pixels, the value of each pixel corresponding to a skin surface temperature;
analyzing said thermal image to stratify said at least one peripheral body part into a plurality of skin surface regions;
identifying skin surface temperatures for each respective skin surface region based on pixels in said thermal image associated with each region;
determining, based on temperature changes of said at least one said surface region of said peripheral body part, whether said subject has peripheral vascular disease.

Abstract
What is disclosed is a system and method for assessing peripheral vascular disease from a thermal image captured using a thermal imaging system. In one embodiment the present method involves the following. First, a thermal image is received of a region of exposed skin of a peripheral body part of a subject being monitored for PVD. The thermal image was acquired by a thermal imaging system. Pixels in the thermal image each have a corresponding temperature value. The thermal image is analyzed to stratify the peripheral body part into a plurality of skin surface regions. A skin surface temperature for each respective skin surface region is identified based on pixels in the thermal image associated with those regions. The temperatures are then extracted such that a progression of temperatures can be ascertained. A method for forecasting the progression for future times is also disclosed.
