Abstract

Every year, approximately 19 million colonoscopies are performed in the US. These are often performed to screen for potentially cancerous polyps. Polyp diameter is currently the best metric for detecting cancer, and is an important aspect of deciding whether to remove a polyp, but physicians struggle to accurately estimate polyp diameter because they have to rely on visual estimation, with only a caliper opening as a reference. Many studies have shown that estimates made by physicians are significantly different than the measurements of polyps taken immediately after excision. Therefore, our team's goal is to create a system involving a software tool that can accurately measure the size of polyps during a colonoscopy and aid physicians. In order to address this need, we have consulted with Dr. Jewel Samadder, a gastroenterologist practicing at Mayo Clinic, and Dr. Vikram Kodibagkar, an image analysis expert. We have decided to build a system that will integrate well with existing endoscopes used currently by physicians. The system will include image processing software that will characterize the size of a polyp selected by the physician, or physician’s assistant, from a still frame of the endoscope video feed. Also, we will create an extendable caliper tool to calibrate the image analysis software. The caliper will be attached to the endoscope, and measure the distance between the polyp and the camera at the end of the endoscope, by having the user extend it one notch of a set length at a time until it comes in contact with the polyp of interest. Therefore, our project will consist of two main parts, the software tool and the caliper tool.
