3. INTRODUCTION
An application of nanotechnology.
A vitamin pill sized camera.
Travels through body and taking pictures.
Helps in diagnosing abnormality in small
intestine.
4. TECHNOLOGIES USED
Pill Camera developed on the basis of
NANOTECHNOLOGY.
Nanotechnology deals with objects measured
in nanometers.
Nanometer can be visualized as billionth of a
meter or millionth of a millimeter or it is
1/80000 width of human hair.
5. DESCRIPTION
Comes in capsule form and contains a camera,
lights, transmitter and batteries.
6. •Video chip : consists of IC CMOS image sensor
which is used to take pictures of the intestine.
•LAMP : It is used for proper Illumination in the
intestine for taking photos.
•Micro actuator: Acts as memory to store the
software code that is the instructions.
•Antenna : Used to transmit the images to the
receiver.
9. Optical Dome : Contains the light receiving window.
Lens Holder : Accommodates the lens.
Lens : Arranged behind the light receiving window.
Illuminating LED: Around the lens and CMOS
image sensor.
CMOS [ Complementary metal oxide semiconductor
]Image Sensor:
Produces very high quality images. High field view
and detect small objects.
Battery : Two button shaped silver oxide primary
batteries are arranged behind CMOS.
ASIC Transistors: Arranged behind the batteries.
Antennae :At the end.
10. WORKING
Pill camera is also called as Capsule
Endoscopy.
The capsule contains a camera, an LED light,
a battery and a built-in antenna.
The antenna transmits the images to a small
recording unit that the patient wears on their
waist during the study.
15. USES
Crohn’s disease.
Mal absorption disease.
Tumors of the small intestine.
Vascular disorders.
Ulcerative colitis.
Medication related to small injury.
16. ADVANTAGES
Painless, no side effect and complications.
Miniature size.
Accurate, precise and effective.
Images taken are of high quality.
Made of bio compatible material.
17. DISADVANTAGES
Patients with narrowing are not good for this
procedure due to risk of obstruction.
Impossible to control camera behavior.
Very expensive.
Not reusable.
18. 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 of the entire
smallest intestine.
It has revolutionized the field of diagnostic
imaging to great extent and has proved to be
of great help to physicians all over the world.
