Photoacoustic imaging is an emerging imaging technique that shoots micro-pulses of laser light at a specimen or body part, which selectively heats up parts of the tissue causing them to expand, and generate waves of pressure –– a.k.a. The photoacoustic imaging technique is beginning to take off in both the medical and scientific worlds, as it provides us with super clear, incredibly detailed images of the human body and the structures inside it.#Medicine #Imaging #Lasers #Technology #Seeker #Elements #Science"Photoacoustic imaging delivers exquisitely detailed images of biological tissue purely by listening to the sound that light makes.
