The Pillcam Colon is a capsule endoscope which measures a mere 11mm x 31mm and comes with tiny cameras on both ends that are capable of capturing a quartet of images per second for up to 10 hours straight. The method of insertion is performed by swallowing the Pillcam with a glass of water. When the procedure is complete, the physician will then download the recorded data to a workstation and review the images captured in order to make a more conclusive diagnosis.

The captured images are transmitted to the sensors on the body. These images then travel from the sensors, along the wires to the datarecorder.
I wonder why they didn’t come up with a bluetooth version.
