A study of thermographic diagnosis system and imaging algorithm by distributed thermal data using single infrared sensor.
The infrared diagnosis device provides two-dimensional images and patient-oriented results that can be easily understood by the inspection target by using infrared cameras; however, it has disadvantages such as large size, high price, and inconvenient maintenance. In this regard, this study has proposed small-sized diagnosis device for body heat using a single infrared sensor and implemented an infrared detection system using a single infrared sensor and an algorithm that represents thermography using the obtained data on the temperature of the point source. The developed systems had the temperature resolution of 0.1 degree and the reproducibility of +/-0.1 degree. The accuracy was 90.39% at the error bound of +/-0 degree and 99.98% at that of +/-0.1 degree. In order to evaluate the proposed algorithm and system, the infrared images of camera method was compared. The thermal images that have clinical meaning were obtained from a patient who has lesion to verify its clinical applicability.
