RKING

OF A PILL

CAMERA

First capsule is swallowed by the patient

The LED illuminates the interior of the stomach & the image sensor records the images

The reciever is worn by the patients in the form of the belt on the stomach

The images are passed through the Transmitting Antenna to the reciever in the form of EM waves and record the images into memory.

A computer workstation process the & the doctor examines the images & diagnose the problem

Images Obtained by Capsule

Camera

ADVANTAGES

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