Researchers have taken an important step in the development of a microscope to precisely guide doctors during surgery to remove brain tumors
For the first time, a team led by engineers at the University of Waterloo used laser imaging technology to almost instantly identify cancerous tissue with accuracy comparable to laboratory tests that take up to two weeks.
That means the Photoacoustic Remote Sensing (PARS) imaging system could tell doctors where a tumor ends and healthy tissue begins so they know exactly where to cut.
“As you can imagine with the brain, doctors need to minimize the amount of tissue they remove because of the impact on the patient,” said Parsin Haji Reza, a systems design engineering professor who leads the project. “There is a very fine line.”
