ABSTRACTImagine a vitamin pill-sized camera that could travel through your body taking pictures, helping diagnose a problem which doctor previously would have found only through surgery.

Pill Camera was invented by Gavriel Iddan in the year 2000 and it was approved by U.S.Food And Drug Administration in 2001.

SPECIFICATION&FEATURES•DIAMETER 10MM

•LENGTH 25MM

•5,000 IMAGES ARE DURING AN 8 HOUR EXAM.

•DISPOSABLE

•CHARGE 8-HOUR

Height-25mm

Width-10mm

Capsule is swallowed by the patient like a conventional pill.It takes images as it is propelled forward by peristalsis.A wireless recorder, worn on a belt, receives the images transmitted by the pill.A computer workstation processes the data and produces a short video clip or still images.

PROCEDURE

Images obtained by capsule camera

Inside a Capsule Camera

Working Pill camera is also called as Capsule Endoscopy. The capsule contains a camera, an LED light, a battery and a built-in antenna. The antenna transmits the images to a small recording unit that the patient wears on their waist during the study.

Crohn's Disease. Malabsorption Disorders. Tumors of the small intestine & Vascular Disorders. Ulcerative Colitis Medication Related To Small Bowel Injury.

USES

Advantages Painless, no side affects or complications. Accurate and effective. Images taken are of very high quality. Made of bio-compatible material, doesn’t cause any harm to the body. small size.Simple procedure.

DISADVANTAGES.

Patients with narrowing are not good candidates for this procedure due to the risk of obstruction.

Impossible to control Camera behavior.

Very expensive.

Not reusable

FUTURE SCOPEZooming and auto focus.

Reduction in size.

Cost effective

Longer battery life

ConclusionPill Camera has a Bright future which will help the doctor to diagnose the stomach related diseases more easily.But some steps need to be taken to overcome the drawbacks.
