DEPENDENCE OF PROSTATE TISSUE PERMEABILITY ON THE WAVELENGTH OF RADIATION IN THE INFRARED RANGE OF THE SPECTRUM

Prostate biopsy is considered to be one of the most aggressive and invasive methods in the diagnosis of prostate cancer. The researchers' efforts are aimed at using alternative and less invasive methods to manifest this disease at an early stage.The authors propose infrared radiation as a method of such research, which, as studies have shown, is characterized by different permeability to tumorous, healthy and hyperplastic prostate tissue, in particular, the more damaged the prostate tissue, the lower its degree of permeability.Experimentally determined that the highest permeability was found in the wavelength range 840-860 nm. It has been found that cancerous, non-cancerous and healthy prostate tissues are characterized by different permeability to infrared radiation. Healthy tissue has been shown to have the highest permeability to infrared radiation. Cancerous tissue permeability is much lower than that of healthy tissue. Prostate tissue permeability with benign hyperplasia is between the permeability of healthy and tumor tissues.Infrared beam transmittance control can be performed by adjusting the radiation intensity of the emitting source. Dependence of permeability on tissue thickness is linear for healthy tissue and sharply non-linear for tumor tissue.
