Dartmouth engineering professor Brian Pogue and his team have developed a Cherenkov image processing algorithm that comes a step closer to enabling its development as a commercial radiotherapy verification tool.

"Researchers at Thayer School of Engineering at Dartmouth have been investigating Cherenkov imaging for use in external-beam radiotherapy for three years," writes Medical Physics Web. "This novel optical imaging technique enables visualization of the radiation dose delivery into tissue. ... The research team has now developed a Cherenkov image processing algorithm that maximizes accurate recovery of beam edges. The algorithm enables quantification of daily variations of intrafraction treatment."
