The document discusses a pill camera, which is a capsule-sized device that can be swallowed to take pictures of the gastrointestinal tract as it passes through the body. It contains a camera, lights, transmitter and batteries and sends over 50,000 color images wirelessly to an external data recorder. The pill camera provides a painless and non-invasive alternative to conventional endoscopy for diagnosing gastrointestinal conditions. While it has advantages over traditional endoscopy, early models had limitations for patients with obstructions, but newer technologies aim to overcome these drawbacks. The pill camera has revolutionized gastrointestinal imaging and diagnosis.

Introduction to Pill Camera
. Imagine 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. .
Conventional Method Endoscopic examination is replaced
by PILL CAMERA.
Description
The device, called the given Diagnostic Imaging System, comes in capsule form and contains a camera, lights, transmitter and batteries.
The latest pill camera is sized at 26*11 mm and is capable of transmitting 50,000 color images during its traversal through the

1.Optical Dome This shape results in easy orientation of the capsule axis along the central axis of small intestine and so helps propel the capsule forward easily. The Optical Dome contains the Light Receiving Window . 2.Lens Holder The Lens Holder is that part of the capsule which accommodates the lens. The lens is tightly fixed to the
3.Lens The Lens is an integral component of the capsule. It is arranged behind the Light Receiving Window. 4.Illuminating LEDs Around the Lens & CMOS Image Sensor, four LEDs (Light Emitting Diodes) are present. These plural lighting devices are arranged in
5.CMOS Image Sensor
CMOS (Complementary Metal Oxide Semiconductor) Image Sensor is the most important part of the capsule. It is highly sensitive and produces very high quality images. It has 140 field of view and can detect 6.Battery objects as small in the capsule is button Battery used as possible. shaped and are two in number as shown. The batteries are arranged together just behind the CMOS Image Sensor. Silver Oxide primary batteries are used (Zinc/Alkaline Electrolyte/Silver Oxide). Such
7.ASIC Transmitter The ASIC (Application Specific Integrated Circuit) Transmitter is arranged behind the Batteries as shown. Two Transmitting Electrodes are connected to the outlines of the ASIC Transmitter. These electrodes are electrically isolated 8.Antennae from each other. As shown, the Antennae is arranged at the end of the capsule. It is enclosed in a dome shaped chamber.
Endoscopy Procedure 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 continuous
Movement Of Capsule Through The Digestive System
DATA RECORDER
COMPUTER
Data Acquisition & Storage Of Data On Computer Produces two images
per second, approximately 2,600
Images obtained by capsule camera
Advantages Painless, no side affects or complications. Miniature size, so can move easily through the digestive system. Accurate, precise and effective. Images taken are of very high quality which are sent almost instantaneously to the data recorder for storage. Made of bio-compatible material, doesnt cause any harm to the body.
Drawbacks & Overcomes
. 1.Patients with gastrointestinal structures or narrowing are not good candidates for this procedure due to the risk of obstruction The first drawback is overcome using another product manufactured with the help of nanotechnology which is the rice- grain sized motor.
2. The Pill will get stucked if there is a partial obstruction in the small intestine. 3. Impossible to control Camera behavior. These two drawbacks can be overcome using a
Wireless Endoscopy
Conclusion The Given Endoscopy capsule 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.
