Pulsed Photothermal Radiometric Depth Profiling of Bruises by 532 nm and 1064 nm Lasers

Abstract: Optical techniques are often inadequate in estimating bruise age since they are not sensitive to the depth of chromophores at the location of the bruise. To address this shortcoming, we used pulsed photothermal radiometry (PPTR) for depth profiling of bruises with two wavelengths, 532 nm (KTP laser) and 1064 nm (Nd:YAG laser). Six volunteers with eight bruises of exactly known and documented times of injury were enrolled in the study. A homogeneous part of the bruise was irradiated first with a 5 ms pulse at 5… Show more

“…By harnessing the power of GPUs, we aimed to achieve improvements in the computational speed of AD calculations. This integration of GPU technology with the AD algorithm holds the potential to advance our understanding of light transport in biological tissues and can pave the way for more efficient simulations and clinical applications, either in HSI [27] or related biomedical optical applications [28,29].…”
