The document describes a pill camera, which is a capsule that contains a camera and travels through the digestive system to take pictures. It is about 26x11mm in size and can capture 50,000 color images. The camera helps doctors diagnose problems without surgery. The pill camera contains components like an optical dome, lens holder, LED lights, image sensor, battery, transmitter and antenna to capture and transmit images. It provides a painless and easy alternative to endoscopy for examining the small intestine. However, it cannot control camera behavior and may get stuck if an obstruction is present. The endoscopy capsule is a pioneering medical technology that has revolutionized diagnostic imaging.

2.  A Pill which consists of a camera is Pill Camera
 It can travel through your body to capture pictures that
helps in diagnosing problems which doctors
previously found through surgeries.
 Size of this is 26*11mm and it has capability of
transmitting 50,000 color images

3.  Endoscopy: Endoscopy is a procedure in
which doctors use endoscope to view and
operate internal organs of a body.
 Examples: Bronchoscopy, Enteroscopy.

5. 1) Optical Dome:
 It is the front part of the capsule and it is bullet shaped
which helps in easy propelling of the capsule.
 It consists of Light Receiving Window.

6. 2) Lens Holder:
 It is that part of capsule that accommodates lens.
 The lens is tightly fixed to the holder so that it does
not dislocated anytime.

7. 3) Lens:
 It is the integral component of the capsule.
4) Illuminating LED’s:
 These illuminate objects.
 Four LED’s are present in donut shape.

8. 5) CMOS Image Sensor:
 CMOS sensor is highly sensitive and produces high
quality images.
 It has 1400 field of view and can detects objects as
small as possible.

9. 6) Battery:
 Silver Oxide primary batteries are used.
 These batteries have good operating period,
disposable and does not cause any harm to the
human body.
 Discharge characteristics of this battery are flatter.

10. 7) ASIC Transmitter:
 ASIC transmitter is arranged behind batteries.
 Two transmitting electrodes are connected to the
outlines of ASIC transmitter.
 These electrodes are electrically isolated from each
other.

11. 8) Antenna:
 Antenna is arranged at the end of the capsule.
 It receives data from ASIC transmitter and sends to
the data recorder.

12.  Painless
 Easy procedure
 Made of bio-compatible material, does not cause any
harm to body.
 The Pill will get stuck if there is a partial obstruction in
the small intestine.
 Impossible to control camera behavior.

13.  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.
