AI-Aided Spectroscopy Assesses Burn Severity to Improve Recoveries
WASHINGTON, D.C., Feb. 17, 2023 — Researchers at Stony Brook University developed a neural network model that uses terahertz time-domain spectroscopy (THz-TDS) to evaluate burns and predict healing outcomes. The latest work builds on a previous advancement in which the researchers developed a portable, hand-held imaging device for fast THz-TDS imaging of burn injuries, which aims to make the method practical for clinical use. Physical changes caused by a burn will produce alterations in the THz reflectivity. For this
