Diffuse Reflection and Energy Distribution of 633, 780, 850, and 940nm Low Power Laser in Brain and Laser Acupuncture for Drug Detoxification of 115 Addicted Patients

摘要

When using low power laser in therapy and diagnostics, the knowledge about the relationship between laser wavelengths and the percentage of reflected energy in the interface air - tissue and the distribution of energy in tissue helps us to choose appropriate wavelengths. In this paper, we present some results obtained from the simulation of low power 633, 780, 850, and 940 nm laser in brain by Monte Carlo method, with the model of brain consisted of 3mm scalp, 5mm skull, 3 mm cerebral cortex & grey matter, and white matter. Based on these results, we fabricated devices called "Laser Semiconductor Optoacupuncture Device" using 780 and 940nm semiconductor lasers to treat some diseases such as cerebral palsy at children, and drug detoxification. In this paper we present the results of dug detoxification for 115 addicted patients using "Laser Semiconductor Optoacupuncture Device.
