Pill cam…


In medicine to record the images of the digestive tract we use the capsule endoscopy. The capsule contains the tiny camera.  Its size is very small. The capsule takes the picture inside the gastrointestinal tract when a patient swallows. The primary function is to examine the small areas of the intestine that can not be possible by another endoscopy.
