Abstract EN

Recently laser applications have been expanding to include many fields.

Among these, are medical laser surgery and biological applications.

It is important to understand the interaction mechanisms that may occur when applying laser light to biological tissues in order to minimize damage to the tissues resulting from extra heat applied.

The aim of this study is to study the temperature distribution in living biological tissues when laser irradiation is used in a treatment by solving bio-heat equation.

The three-dimensional finite element thermal model FEMLAL3.2 of biological tissues is developed using bioheat equation to study the impact of several parameters such as laser power, exposure time, laser spot size on the temperature distribution within tissues when subjected to a laser source, to determine the appropriate dose to be applied to the treated area without damaging nearby healthy tissue.

The results are calculated in details using FEMLAB3.2.

The resulting solutions are expected to be useful in a variety of laser applications medicine and surgery.
