Abstract
Capsule endoscopy (CE) uses a miniature on-board camera in a pill for imaging gastrointestinal (GI) tract. It has provided a non-invasive and non-ionization way for gastroenterologists to diagnose GI tract diseases. However, CE has major drawbacks such as ineffective forward-looking field of view (FOV), abundant data, and lengthy viewing and interpreting time, significantly lowering the chance of finding a GI disease through the video screening process. We present a concept of utilizing full spherical field of view imaging for easy visualization. Built on camera pose tracking and 3D algorithms under spherical viewing field of view (FOV), through immersive display or VR, the technology is shown to allow clinicians to visualize interested pathological structures at finger tips on a VR device. Initial test results on phantoms show that our design is feasible.
