Sensor device invention controls laser surgical cut

Queen's University professor James Fraser and his doctoral student, Paul Webster, have come up with a sensor device designed to control how deep a laser cuts during surgeries. The university, based in Ontario, Canada, isn't discussing a lot of details about the technology. But Fraser, in a statement, explained that their new device is designed to control the depth of a laser cut, allowing lasers to be used during surgery more often. "There are many surgical procedures where we could like to use lasers but we can't because they are too difficult to control," Fraser said. "Our technology may enable new laser surgeries that weren't possible before." Release
