The document discusses the capsule camera, a vitamin pill-sized device that captures images inside the digestive system for diagnostic purposes, overcoming limitations of traditional methods like endoscopy. It details the camera's components, the procedure for its use, and its applications in identifying various gastrointestinal conditions. The advantages include being painless and providing high-quality images, while drawbacks like the risk of obstruction are addressed through advanced technologies.

- 3. Introduction to Capsule Camera Imagine a vitamin pill-sized camera that could travel through yourbody taking pictures, helping diagnose a problem which doctorpreviously would have found only through surgery.
- 4. Conventional Method The conventional method that Doctors would have prefered 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 either an eyepiece for direct viewing or Video screen that displays the images on a colour tv.This Procedure used for Gastro Intestinal(GI) disease and treatment as well…
- 5. Description… Thedevice, called the Diagnostic Imaging System, comesin capsuleform and containsacamera, lights, transmitter and batteries. Thelatest pill cameraissized at 26*11 mm and iscapable of transmitting 50,000 color imagesduring itstraversal through the digestivesystem of patient.

- 7. 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 holder so that it doesn’t get dislocated anytime. Components…
- 8. 3.Lens 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. Components…
- 9. 5.CMOS Image Sensor 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. Components… 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
- 10. 7.ASIC Transmitter 8.Antennae As shown, the Antennae is arranged at the end of the capsule. It is enclosed in a dome shaped chamber. Components… 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 Electrode are electrically isolated from each other.
- 11. Procedure Of Capsule Cam 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.
- 12. DATA RECORDER COMPUTER Movement Of Capsule Through The Digestive System Data Acquisition & Storage Of Data On Computer Produces two images per second, approximately 2,600 high quality images.

- 15. Advantages … Painless, no side affects or complications. Small size, so can move easily through 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.
- 16. Drawbacks & Overcomes … 1.Patients with gastrointestinal structures or narrowing are not good candidates for this procedure due to the risk of obstruction. 2.The Pill will get stucked if there is a partial obstruction in the small intestine. 3.Impossible to control Camera behavior. The first drawback is overcome using another product manufactured with the help of nanotechnology which is the rice- grain sized motor. Other two drawbacks can be overcome using a bi-directional telemetry Camera..
- 17. Conclusion The Capsule Endoscopy 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. Pill Camera
