A method based on optical coherence tomography (OCT) could improve the abilities of scientists and medical personnel to evaluate biopsies. The technique, developed by researchers at TU Delft, images four times deeper than traditional OCT approaches.
As opposed to a traditional OCT scan, the researchers using the method do not make images with reflected light, instead sending the light directly through tissue. A sensor on the other side captures the light, measuring the specific wavelengths that arrive — and when.
Researcher Jeroen Kalkman stands next to his new imaging setup. Courtesy of TU Delft. “The light that travels for a longer period of time is scattered though the tissue and arrives at the detector relatively…
