Evaluating the control of the adaptive display rate for video capsule endoscopy diagnosis

The excessively long reviewing times for diagnosis of capsule endoscopy present a clinical problem. A new method, ldquoadaptive speedrdquo, which automatically controls display rates of the video capsule endoscopy images, was proposed to address the problem. In this paper, we investigate the effectiveness of this method versus a standard-view using the existing system. The main activities of examining doctors during a series of evaluations using both systems are recorded. For comparisons, logged actions are analyzed to show three criteria: 1. Diagnostic time, 2. Ability to capture abnormal regions, and 3. Operability for the examining doctors. We conclude that adaptive speed reduces examination time by ten minutes from that of the existing system, while the number of abnormalities found are similar. As well, examining doctors need less effort because of the systems efficient operability.
