A new endoscopy technology called photometric stereo endoscopy (PSE), which can capture the topography of the colon surface to create a three dimensional (3D) image, could be a more robust way to screen for precancerous lesions of the colon. Researchers at the Massachusetts Institute of Technology and Harvard Medical School developed the technology to improve on the standard 2D imaging of traditional endoscopies that can sometimes miss or incorrectly classifies certain lesions.

The new technique creates both a 3D image and the standard 2D imaging, providing more information for a clinician to make a better diagnosis. The results are published in the Journal of Biomedical Optics.


According to the American Cancer Society, more than 142,000 new cases of colorectal cancer will be diagnosed in the United States this year, and more than 50,000 people will die from the disease.
