A system and method is provided for automated polyp detection in optical colonoscopy images. The system includes an input configured to acquire a series of optical images, and a processor configured to process the optical images. Processing steps include performing a boundary classification with steps comprising locating a series of edge pixels using at least one acquired optical image, selecting an image patch around each said edge pixel, performing a classification threshold analysis on each image patch of said edge pixels using a set of determined boundary classifiers, and identifying, based on the classification threshold analysis, polyp edge pixels consistent with a polyp edge. Processing steps for the processor also include performing a vote accumulation, using the identified polyp edge pixels, to determine a polyp location. The system also includes an output configured to indicate potential polyps using the determined polyp location.

Devices and systems have a sensor probe configured to measure tissue oxygen saturation in the intestine or mesentery. The devices and systems can determine the oxygenation state of the entire thickness of the intestine or mesentery. Embodiments of the invention also include methods for inducing a temporary ischemic period in an intestine or mesentery tissue and analyzing changes in oxygen saturation of the tissue during the temporary ischemic period or during a recovery phase. The devices, systems, and methods can be applied in diagnosing intestinal ischemia in a patient, as well as in monitoring tissue oxygen saturation of the intestine or mesentery during or after a surgical procedure.

This invention relates to a robot to improve the inspection of a pipe or lumen. More particularly, this invention relates to a soft-pneumatic robot for endoscopy that is suitable for performing colonoscopy procedures. The robot of this invention comprises leading and tailing balloons configured for selective inflation to anchor a portion of the robot within the pipe or lumen and a soft-pneumatic actuator that is located between the leading balloon and the trailing balloon. The soft-pneumatic actuator is operable to extend or contract the robot in a longitudinal direction, in addition to positioning the leading balloon in a 360 degree circumference around the longitudinal direction by pneumatically controlling a fluid within a plurality of chambers within the soft-pneumatic actuator.
