Non-destructive detection system and method for skin tumors on basis of frequency modulation excitation thermal map

Abstract

The invention discloses a non-destructive detection system and method for skin tumors on the basis of a frequency modulation excitation thermal map. The system comprises a thermal infrared imager assembly, a thermal excitation source, a function signal generator, a light modulator and a data receiving and processing device; the thermal infrared imager assembly includes an infrared thermography head, and the thermal excitation source includes a halogen lamp head. The method includes the following steps of adjusting the position of the thermal infrared imager assembly; adjusting the focal lengthof the infrared thermography head until a clear infrared image is displayed; adjusting the thermal excitation source to converge lamp holder apertures in the thermal excitation source to a to-be-detected part; inputting and determining a frequency modulation signal in the data receiving and processing device, outputting the frequency modulation signal to the function signal generator and redetermining the frequency modulation signal in the function signal generator; turning on a halogen lamp assembly power source and collecting image data of the to-be-detected part. Compared with the prior art, the system and method in the scheme have the advantages that patients have no painful feeling in a diagnostic process, the detection cost is low, and a detection result is accurate and reliable.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a system and method for nondestructive detection of skin tumors based on frequency modulation excitation heatmaps. Background technique [0002] With the increasingly serious destruction of the atmospheric ozone layer, the amount of ultraviolet radiation has also increased, resulting in an increase of 4% to 6% in the incidence of skin cancer worldwide. Skin tumor is the most common type of cancer. At least 85% of clinically diagnosed cancers originate from epithelial tissue. Skin is the largest organ in the human body, and epithelial tissue is an important part of the skin. The onset of skin tumors can be divided into early, middle, and late stages. The early symptoms of skin tumors are not obvious. When skin tumor patients are found, they are already in the middle or late stages of cancer and miss the best opportunity for treatment. Therefore, early and rapid skin cancer detect...

Problems solved by technology

However, for the special clinical medical application of early detection of skin tumors, it is necessary to detect tumors located at a certain depth under the skin under the action of low-power thermal excitation acceptable to the human body, and the above methods are difficult to work
