Application of the method of Mueller-matrix tomography of tissues and blood for precise determination of blood loss degree.

Abstract

Accurate determination of blood loss degree is very important for forensic medical experts, as it helps to objectively assess traumatic injuries, determine the circumstances of death, and contribute to justice in legal proceedings. Determining blood loss volume is especially important in cases of violent death, accidents, and in cases of massive blood loss due to disease. Modern methods often have limited accuracy, which can affect the objectivity of conclusions and lead to possible errors in judicial decisions. Therefore, it is urgent to develop more accurate technologies, such as the laser polarimetry method, to increase the reliability of forensic medical examinations, improve the quality of forensic conclusions, and contribute to a more objective determination of the causes and circumstances of death. The aim of the study. Development of objective forensic criteria for digital differential Mueller-matrix tomographic diagnostics of the volume of acute blood loss. Material and methods. Samples of biological tissues and blood were collected from 82 deceased people with various degrees of blood loss in the range from 0 mm³ to 3000 mm³. The study was conducted using the Mueller-matrix tomography method of biological tissues according to proposed algorithm.
