THz PHASR Scanner in operation (IMAGE) Optica Caption Researchers developed a new physics-based neural network model that uses terahertz time-domain spectroscopy (THz-TDS) data for non-invasive burn assessment. They combined the new approach with the handheld imaging device shown, which was developed for fast THz-TDS imaging of burn injuries.
