1.OPTICAL DOME The optical Dome contains the light receiving window. The window

along with container are sealed to prevent infiltration of digestive fluids inside the capsule.

2.LENS HOLDERThe lens holder is that part of the capsule which accommodates the lens.

3.LENSThe lens is that part of the pill camera arranged behind the Light Receiving window.

4.ILLUMINATING LEDAround the Lens & CMOS Sensor, four LEDs (Light Emitting Diodes) are present. These plural lighting devices are arranged in donut shape.

5.CMOS IMAGE SENSORCMOS (Complementary Metal Oxide Semiconductor) produces very high quality images.

6. BATTERYSilver oxide primary batteries are used (Zinc/Alkaline electrolyte/Silver oxide). Such a battery has a even discharge voltage, disposable.

7. ASIC TRANSMITTERTwo transmitting electrodes are connected to the outlines of ASIC (Application Specific Integrated Circuit) Transmitter.

8. ANTENNAThe dome containing the antenna is made of conducting material which is harmless to the human body. Parylene coated on to poly ethylene or polypropylene is used.

Small portable recording device.

Placed in the recorder pouch.

WORKSTATION AND RAPID SOFTWARE

REVIEW AND ANALYSIS

Real time viewer

Handheld device.

Enables Real-Time viewing.

Contains RAPID Reader software.

Colour LCD monitor

PROCEDURECapsule is swallowed by the patient like a conventional pill.

It takes image as it is propelled forward by peristalsis.

A wireless recorder worn on a belt, receives the image transmitted by the pill.

A computer workstation processes the data & produce a continuous still images.

DATARECORD

ERCOMPUTER

Fasting for 4 hours

Swallow the capsule with few sips of water

Patient can leave the center

After 7-8 hours the patient must return

Collect images from data recorder and examine it

ADVANTAGES OF PILLCAMPainless No side effectsAccurate pictures(view of 150 degree)High quality imagesEasy procedureHigh sensitivity and specificityNo sedation is requiredMore efficient than X-ray ,CT-Scan and normal endoscopy
