Method and device used for testing of the absorbed dose of radiation during low level laser therapy

摘要

A method of control of the absorbed dose of radiation during low-level laser therapy is proposed. It is based on registration of both the reflected part of energy and part of energy spent on local heating of epidermis. Results of theoretical and experimental studies of heating process at pulse action are presented. As a device controlling the absorbed dose a therapeutic machine is proposed. The intensity of its action can be adjusted depending on optical and thermophysical properties of the biological tissue.
