Introduction
pill-sized camera is the camera that could travel through your body taking pictures.
The pill camera is sized at 26*11 mm and is capable of transmitting 50,000 color images during its traversal through the digestive system of patient.
History
Pill camera was approved by FDA(food and drug
administration) in 2001.
The Israeli company Given Imaging Ltd. has received official approval to market the video capsule to physicians within European Union countries in 2001.Then later on it was used in other countries.
Conventional Method The conventional method that Doctors would have preferred earlier was
Endoscopy Procedure .By which Doctor able to see the inside lining of digestive tract.This Examination is performed using an Endoscope-a flexible fiber optic tube with a tiny TV camera at the end.The camera is connected to Video screen that displays the images on a colour tv.This Procedure used for Gastro Intestinal(GI) disease .
Drawbacks of endoscopy Drugs effect Complex procedure Infection Painful etc

Architecture of Capsule Camera
1.Optical Dome
Front part and Bullet shaped
Non-conductor
Easy orientation of the capsule along the intestine and helps
propel the capsule forward easily.
Light receiving window
2.Lens Holder It is that part of the capsule which accommodates
the lens. The lens is tightly fixed to the holder so that it doesn’t get
dislocated anytime.
Components
3.Lens It is an integral component of the capsule.
It is arranged behind the optical dome.
5.CMOS Image Sensor
CMOS(Complementary Metal Oxide Semiconductor) Image Sensor.
It is highly sensitive and produces high quality images.
It can detect objects as small as possible.
4.Illuminating LED’S
Light from the LED pass through the light receiving
window.
6.Battery Button shaped and are two in number. The batteries are arranged together just behind the CMOS Image Sensor.
7.ASIC Transmitter
Silver Oxide primary batteries are used.
Disposable and doesn’t cause harm to the body.
The ASIC (Application Specific Integrated Circuit) Transmitter is arranged behind the Batteries.
8.Antenna Antennae is arranged at the end of the capsule. It is enclosed in a dome shaped chamber. Antenna received data from transmitter.
Procedure First Sensor Array ,Data recorder, which are incorporated with in a belt are worn by the patients .
Then capsule is swallowed by the patient like a conventional pill. And the camera takes images as it is propelled forward.
Sensor array is used to calculate and indicate the position of the capsule in the body and receives the images transmitted by capsule.
Then the data recorder records the images transmitted by capsule and received by sensor array.
Then a computer processes the data and produces continuous still images.
Crohn's Disease
Mal-absorption Disorders.
Tumors of the intestine & Vascular Disorders.
Gastrointestinal reflex.
Small Bowel Injury.
Applications
Advantages Small size
Painless, no side affects or complications
Precise and effective.
High quality images
Simple procedure
Efficent than endoscopy.
Disadavantages
Gastrointestinal obstructions prevent the free flow of capsule.
Patient pregnant women face difficulties.
It is very expensive and not reusable.
It cannot be controlled once it has been ingested.
Conclusion
It has revolutionized in the field of diagnostic imaging to a
great extent and has proved to be of great help to
physicians all over the world.
If it becomes little cheaper and drawbacks are overcomed, then
hopefully it will replace the conventional endoscopy method
completely .
