| - | In colonoscopy, it is important to monitor the progression or recurrence of suspected cancerous lesions (e.g., polyps). Because the colon is contractile and mobile, however, it is very difficult to relocate a lesion (e.g., a polyp) even during the same procedure. We are developing a novel 360 degree panoramic imaging method to build a map of colon lining, during colonoscopy, and use it to locate and track cancerous and pre-cancerous lesions. This research will make colon cancer screening and treatments more effective. | + | In colonoscopy, it is important to monitor the progression or recurrence of suspected cancerous lesions (e.g., polyps).

| + | A motion tracking device was previously developed to provide the accurate position, rotation, and velocity of the endoscope to be used in both upper and lower gastrointestinal procedures. It will help gastroenterologists during examination, diagnosis, treatments, and follow-ups to record precise location information during a procedure whether it is for determining the exact area for follow-ups, training doctors, or comparing the size of a tumour. In the current phase, this prototype design is being optimized using modern camera and imaging features as well as hardware and software design to produce a more efficient product that can be used in a clinical setting. The benefits of this design as compared to other solutions are the cost-effective, small-sized, real-time, and software based approach that can simplify the design and minimize the weight of the device. It is also placed externally on the endoscope and does not go inside the patient which allows for it to be removed or disposed. | ||
