Researchers at Skoltech are a step closer to a working optoacoustic endoscopic probe — a device that could slip inside a blood vessel and analyze atherosclerotic plaques by shining laser light on them and making them vibrate like a speaker membrane. This effect would cause the plaques to betray their chemical composition with an ultrasound signature. The method, if it can be achieved, would prove useful for robotic microsurgeries and medical diagnostic procedures. Unlike a CT scan, optoacoustic imaging does not use x-rays or other harmful radiation. It instead relies on visible...Read full articleRelated content from Photonics MediaARTICLESTerahertz Optoacoustic Method Images Water-Rich SamplesA research team led by Zhen Tian and Jiao Li at Tianjin University developed a method for analyzing water-rich samples using time-domain terahertz (THz) optoacoustics.
