A team of University of Alberta engineers is refining a new imaging technique that could reduce the number of repeat surgeries patients undergo to remove cancerous tumors.
The team, led by Roger Zemp, is using ultraviolet photoacoustic remote sensing microscopy (UV-PARS) to rapidly visualize and analyze tumor tissue while patients are still on the surgical table, to more effectively check whether the entire tumor has been removed and ensure no repeat surgeries are needed.
The current medical practice to determine whether an entire tumor has been removed during surgery, called histology, involves pathologists examining…
