Abstract

The patient experiences trouble walking and surviving as a result of tibia fractures or tibial osteoporosis. The tibia, a crucial bone in the lower extremities that requires the longest recovery time, as well as the relatively low level of activity in the legs, are both factors. In the patient's day-to-day existence, this has a substantial effect. Regenerating tissue, reducing pain, and reducing inflammation are all effects of low-level laser light. In this work, the effects of lasers of four different wavelengths—633 nm, 780 nm, 800 nm, and 940 nm—were examined using the Monte Carlo approach. We put the curve fitting technique into practice using the parameters we learned from the outcomes of the many Monte Carlo simulations. With an RSME of 2.62% and 1.32%, respectively, the findings demonstrated the link between energy and beam radius with regard to depth. We anticipate that the study will provide a quick analysis of how laser beams affect different regions in order to improve treatment settings.
用蒙特卡罗方法模拟低强度激光从皮肤表面到胫骨的传输
由于胫骨骨折或胫骨骨质疏松,患者行走困难,生存困难。胫骨是下肢的重要骨骼,需要最长的恢复时间,而腿部的活动水平相对较低,这两者都是影响因素。在病人的日常生活中,这有很大的影响。再生组织,减轻疼痛,减少炎症都是低强度激光的效果。在这项工作中,使用蒙特卡罗方法研究了四种不同波长的激光器(633 nm, 780 nm, 800 nm和940 nm)的影响。我们将曲线拟合技术应用到实践中,使用我们从许多蒙特卡罗模拟的结果中学到的参数。RSME分别为2.62%和1.32%,表明能量与波束半径在深度上存在关联。我们期望这项研究能够快速分析激光束对不同区域的影响,从而改善治疗环境。
