Abstract
Acute myocardial infarction is one of the major diseases leading to death and disability worldwide. A rapid, noninvasive and direct diagnostic method of ischemic heart disease is helpful to improve the condition. Photons propagation at 850nm by Monte Carlo simulation and photon distribution in thoracic tissues were studied firstly based on the Visible Chinese Human Dataset (VCH). Quantitative results of absorption photons and light fluence distribution indicated partial photons could reach to myocardium. In simulation result, 32% photons were absorbed by the myocardium. The light fluence intensity declined with the tissue depth. When light reaches the heart, the light intensity decreases 10,000 times. The feasibility of near-infrared light applied in the heart and transmission to the myocardium was verified firstly by mathematical simulation, which may provide a novel method for monitoring myocardial hemodynamics.
