Until the early 2000’s, direct visual diagnosis inside the human small intestine was limited to arduous and costly surgical procedures.  The advent of Wireless Capsule Endoscopy (WCE), using a small camera inside a capsule with a radio transmitter, allowed patients to swallow the capsule then go about their normal day while a small radio receiver compiled the image data.  

This technology revolutionized the way patients with suspected small bowel disease were managed and significantly added to the knowledge of how small bowel disorders manifest and progress, and how they respond to treatments.

However, power consumption rates created procedure times limited to 8 hours at best.  Low image resolution, low compression ratios and limited controllability affected the completeness and quality of procedures, and very long review times for physicians created additional barriers to adoption. Since that time, software innovations have decreased review times, but limits still exist for patients and physicians due to power management issues.
