Researchers at University College London (UCL) have developed a miniaturized scanner using laser light and ultrasound waves for real-time, high-detail medical imaging, marking a significant advancement in the field. This new technique, called Photoacoustic Tomography (PAT), allows for quick imaging of biological tissues, particularly effective in visualizing blood vessels. The team has managed to reduce the imaging time to under a second, which could facilitate the use of a hand-held scanner in clinical settings, eliminating the need for harmful X-rays and expensive MRI machines. This technology has the potential to diagnose and manage diseases like arthritis, diabetes, and various cancers. A recent trial demonstrated its capability to reveal critical blood flow issues in patients with early-stage diabetes. Additionally, it may enhance surgical outcomes in cancer treatments by helping surgeons distinguish between tumor tissue and healthy tissue based on blood vessel visualization. Although promising, further research is needed with larger patient groups before the PAT scanner can move toward routine clinical use.
