Photoacoustic Device Probes Tissue with Low-Cost Laser Diodes
INDORE, India, March 5, 2024 — Photoacoustic (PA) technologies offer a noninvasive approach to probing biological tissues, but have seen limited use in clinical applications, partially due to bulky, expensive laser sources. A compact photoacoustic (PA) sensing instrument for biomedical tissue diagnosis, powered by laser diodes, could provide clinicians with a practical, effective tool for evaluating breast disease. By providing a cost-effective path to tissue diagnosis, the compact PA sensing instrument could bridge
