Comparative Studies of Digital Plethysmography and Infrared Thermography in Peripheral Vascular Disease

Disclosure of the significant thermal effects of large blood vessels during cryosurgery through infrared temperature mapping

“…When superficial large vessels have some pathological changes, the corresponding changes in its thermal effects can reflect to the temperature distribution at skin surface. Based on this principle, the infrared thermographic system has been widely used in the diagnosis of some vascular diseases [16][17][18][19][20][21]. Considering this feature of infrared thermographic system, we will attempt to use it to study the thermal effects of large blood vessels in the cryosurgical procedure.…”
