Ultrasound microscopy: An aid for surgeons to make the invisible, visible. Professor Naohiro Hozumi of Toyohashi Tech is developing the technology to monitor living tissue and cell specimens for medical purposes.The ultrasonic microscope emits a high frequency sound at an object, and the reflected sound captured by its lens is converted into a two dimensional image of the object under scrutiny.This data can potentially help surgeons differentiate between types of tissue.
