Photoacoustics Holds Promise for Cancer
Diagnosis and monitoring of cancer are two of the top potential uses for PA technologies. This is the first of a two-part series that will look more closely at the work of the dedicated researchers making some of the most exciting recent (and future) advances in photoacoustics. Photoacoustics is expanding at, well, the speed of light these days. Sound-and-light-based imaging is one of the most quickly growing bioimaging modalities, according to journal publisher Elsevier, which last year
