ONVENTIONAL METHOD C● Currently, standard method of detecting abnormalities in the intestines is through endoscopic examination● But these scopes are unable to reach through all of the 20-foot-long small intestine, and thus provide only a partial view of that part of the bowel.

How does it works???●The patient swallows the capsule and the
natural muscular waves of the digestive tract propel it forward through stomach, into small intestine, through the large intestine.
●It takes snaps as it glides through digestive tract more than twice a second.
12/09/2013 23
How does it works???
●Capsule transmits the images to a data recorder, which is worn on a belt around the patient's waist.
●The physician then transfers the stored data to a computer for processing and analysis.
●The complete traversal takes around eight hours and after it has completed taking pictures it comes out of body as excreta.

ISADVANTAGESD1.Patients with gastrointestinal structures or narrowing are not good candidates for this procedure due to the risk of obstruction.
2. Patients with pacemakers, pregnant women face difficulties. 3.The Pill will get stucked if there is a partial obstruction in the small intestine.
4. Impossible to control Camera behavior. 5.Very expensive.
6.Not reusable12/09/2013

Pill camera is a pioneering concept for Medical Technology of the 21st century.
The endoscopy system is the first of its kind to be able to provide non-invasive imaging of the entire small intestine. It has revolutionized the field of diagnostic imaging to a great extent and has proved to be of great help to physicians all over the world.
Nanotechnology has the power to revolutionize the world of production.
