capsule endoscopy
nounMedical Definition of capsule endoscopy
: visualization of the interior of the digestive tract by means of a wireless camera encased in a pill-sized capsule that is swallowed
The concept of capsule endoscopy is quite simple—the patient swallows a small camera which takes pictures as it tumbles through the length of the digestive tract … . The capsule contains a light source that acts as a flash, a camera for taking pictures, and a transmitter that sends the images for storage to a device worn around the patient's waist.— Benjamin Siemanowski, The Bellingham (Washington) Herald, 12 Dec. 2009
