Our team has created an automated, real-time software based image analysis tool called Colometer to improve screening colonoscopy providing real time visual feedback on image quality. There are three components to this study. The first is to validate the bowel assessment preparation using the recorded colonoscopy videos from 50 consented normal risk patients. In the second phase, technological and machine user interface refinements will be identified and completed. Finally, the third phase will be a sham controlled prospective study of Colometer versus standard care in 100 consented average risk patients undergoing screening colonoscopy as performed by 10 consented endoscopists.

%Clear
This is defined as the Percentage of the total withdrawal time where the withdrawal velocity is below a set speed limit and the view is clear (ie, not blurry) as measured by the software. Visualization of the colon lumen is ideal with a slow, non-blurry view in order to detect polyps.
Time frame: Measurement will occur during the withdrawal phase as indicated by the physician during the colonoscopy procedure; on average, 12 minutes
Average withdrawal velocity
Time frame: Measurement will occur during the withdrawal phase as indicated by the physician during the colonoscopy procedure; on average, 12 minutes.
