Evaluation of low-intensity laser external radiotherapy through thermal texture mapping (TTM) technology

This paper aims to evaluate the curative effects of low-intensity laser external radiotherapy through thermal texture mapping (TTM) technology. The influences of 30 min nasal cavity irradiation of semiconductor laser (650 nm, 5 mW, continuous wave) on microcirculation were investigated through TTM. At the same time, with the aid of TTM, the influences of the irradiation on the whole body thermal balances and the functions of the liver and kidney were also studied. Altogether, 32 cases of microcirculation depression were investigated. After the 30 min nasal cavity irradiation, the total efficiency of microcirculation reached 100%. The effective ratio kept 96.9% 30 minutes later but the effect almost disappeared completely 150 minutes after the irradiation. No ill influence on the whole body thermal balance or metabolic functions of liver and kidney was found. Low-intensity laser external radiotherapy was a promising therapy to improve microcirculation. TTM was the ideal evaluation technology promoting this therapy.
