The document discusses the pill camera, also known as the capsule camera, which was introduced by Gabriel Iddan in 2000 and is FDA approved for diagnosing stomach-related problems. It highlights the camera's components, how it works, and its advantages over traditional endoscopy, such as being painless and non-invasive, although it can be expensive and may get stuck in the intestines. The system consists of a disposable camera, LEDs, a battery, and a built-in antenna, allowing for high-quality imaging of the gastrointestinal tract.

3.  A Pill Camera is also called as Capsule Camera
 Introduced in the year 2000 by Gabriel Iddan
 Approved by U.S. Food & Drug administration
 The camera has the size of the pill or a capsule which will go inside
the body
 Helps to diagnose the stomach related problems by going inside
the body
 Reduce the drawback of painful endoscopy

4.  Consists of a Disposable Camera, Disposable LEDs, a Battery, & a
built-in Antenna
 This whole System is known as the Diagnostic-Imaging System

5.  Pill Camera can easily diagnose stomach related
problems without any severe pain
 Earlier a process called Endoscopy was used which
was painful and required sedation
 Patient has to only eat the pill and all the stomach
related problems can be diagnosed

6. The Pill Camera consist of the following important parts
 Optical Dome
 Lens Holder
 Lens
 CMOS Image Sensor
 Battery
 ASIC Transmitter & Antennae

7.  This shape results in the easy orientation of the capsule axis along
the small intestine
 The Optical Dome consists of the Light Receiving Window

8. Lens holder accommodate the Lens such
that the Lens does not get dislocated

9.  Most important component of the capsule
 Arranged behind the Light Receiving Window
 The Light through the window falls on the Lens

10. ILLUMINATING LEDS
 Placed around the Lens & the Image Sensor
 Helps to illuminate the parts inside the
stomach

11.  Another most Important Part of a Pill Camera
 CMOS sensor is used to record high quality
Images
 Has 140 degree field of view & can detect
objects of 0.1mm

12.  The battery is placed behind the Image
Sensor and is in the form of a small button
 Battery is made up of Silver –Oxide which is
disposable & not harmful to the body

13.  ASIC(Application Specific Integrated Circuit)
Transmitter is received behind the batteries
with an antenna
arranged at the end of the capsule.
It is enclosed in the dome shaped Chamber

14.  First capsule is swa
by the patient
 The LED illuminate
interior of the stoma
the image sensor re
the images
 The reciever is wor
patients in the form
belt on the stomach
 The images are pas
through the Transm
Antenna to the reci
the form of EM wav
record the images i
memory.
 A computer worksta
process the & the d
examines the imag
diagnose the proble

16.  No side effect
 Painless as compared to endoscopy
 Don’t cause any harm to the body
 Consumes Less time & gives good
results

17.  Pill Camera is very
Expensive
 Doctors will charge huge
fee from the patients for
carrying this test
 Sometimes, Camera can
get stuck in the small
intestines if there exists
some obstruction inside
intestines
