ABSTRACT
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.
Pill Camera was invented by Gavriel Iddan in the
year 2000 and it was approved by U.S.Food And
Drug Administration in 2001.

SPECIFICATION&FEATURES
• DIAMETER 10MM
• LENGTH 25MM
• 5,000 IMAGES ARE DURING AN 8 HOUR
EXAM.
• DISPOSABLE
• CHARGE 8-HOUR
Height-25mm
Width-10mm

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 short video clip or
still images.
