Skin surface irregularity is the most common problem resulting from liposuction. It is caused by partially tilted internal boundaries between the fat and muscle layers after inappropriate liposuction. From the point of view of biomedical engineering, it is meaningful to simulate the light propagation according to the slope angle of the boundary with a specific light source. Therefore, in this paper, we suggest a method with which to simulate light propagation according to the angle of the boundary, based on Monte Carlo simulation commonly used for light propagation simulation in tissue, using a radial-beam light-emitting diode (LED). We first consider three characteristics of the radial-beam LED in tissue and perform selective transformations for the effects of the slope angle of the boundary in multiple layers. An experiment is then carried out to verify the effectiveness of the simulation we proposed. The coefficient of correlation between the simulation and experimental results is found to be 0.9605. From our results, we conclude that our simulation method is valid for light propagation through a tilted multi-layer tissue using a radial-beam LED.
