"How does PillCam SB capsule endoscopy work?
A: The smooth plastic capsule contains a miniature video camera and is equipped with a light source on one end, batteries, a radio transmitter and antenna. After it is swallowed, the PillCam SB capsule transmits approximately 50,000 images over the course of an 8-hour period (about 2 images per second) to a data recording device attached to a belt worn around the patient’s waist. The small bowel images are then downloaded into a GivenŽ Workstation computer where a physician can review the images in order to make a diagnosis"
Ask my doctor for a pill cam. Thanks for the info, JewishIsrael.
