Can light and sound replace X-Rays? a new imaging method aims to see inside without radiation

This trial tests a new imaging method called ultrasound optical tomography (UOT), which combines ultrasound and laser light to create images of tissues inside the body. The goal is to see how deep the technique can image and how well it can measure tissue oxygenation in healthy volunteers. Unlike X-rays, UOT does not use ionizing radiation, making it potentially harmless. The study is an early step toward developing a safer imaging tool for future use in diagnosing conditions like breast cancer.
