In the past decade, imaging based on the #photoacoustic ( #PA ) techniquehas emerged as a viable imaging modality demonstrated in many clinical applications with promising outcomes.

Unlike traditional methods, #PA offers a noninvasive approach to probing biological tissues, yet the technique has still been limited in wide clinical applications, partially due to bulky and expensive laser sources.
In a recent study published in the Journal of Biomedical Optics, researchers from the Indian Institute of Technology Indore unveiled a groundbreaking advancement-;a compact and cost-effective PA sensing instrument designed specifically for biomedical tissue diagnosis.
This proof-of-concept study employs low-cost diode laser.
It represents a crucial step towards bridging the gap between laboratory research and clinical applications.
