PILL CAMERA By Ok fine VIJITH.P.K

A PILL WITH VIEW This is also ok but what ‘ll u explain here

CONTENTS Introduction to Pill Camera Conventional Method Specification Components of Pill Camera Inside a Pill Camera Endoscope Procedure Advantages Drawbacks & Overcomes Conclusion

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.

Specification Diameter 11mm. Length 26mm. Less than 4g.

Components Of Pill camera LIGHTING DEVICE LENS CMOS IMAGE SENSOR TRANSMITTING ELECTRODE

Inside a Pill Camera ASIC OPTICAL DOME ANTENNA 5 7 LENS HOLDER TRANSMITTER LENS BATTERY ILLUMINATING LED’S CMOS IMAGE SENSOR

1.Optical Dome 2.Lens Holder 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 holder so that it doesn’t get dislocated anytime.

3.Lens 4.Illuminating LED’s The Lens is an integral component of the capsule. It is arranged behind the Light Receiving Window. 4.Illuminating LED’s Around the Lens & CMOS Image Sensor, four LED’s (Light Emitting Diodes) are present. These plural lighting devices are arranged in donut shape.

5.CMOS Image Sensor 6.Battery 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 140º field of view and can detect objects as small as possible. 6.Battery Battery used in the capsule is button 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 a battery has a even discharge voltage, disposable and doesn’t cause harm to the body.

7.ASIC Transmitter 8.Antennae 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 from each other. 8.Antennae 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 still images.

Movement Of Capsule Through The Digestive System DATA RECORDER COMPUTER Data Acquisition & Storage Of Data On Computer

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, doesn’t 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 bi-directional telemetry Camera. .

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.
