A New Method for Colorectal Cancer Screening: Colon Capsule Endoscopy Compared to Conventional Endoscopy

The PillCam® Colon Capsule is 11mm x 31mm in size (Figure 1), is equipped with two cameras acquiring pictures from both ends of the capsule at a rate of 4 frames per second (2 pictures per second and camera). The PillCam® Colon Capsule is automatically activated when it is removed from the package. It enters sleeping mode after approximately 10 minutes and starts transmitting again 1 h 45 min later. It has a total operating time of 8 - 10 hours. During the examination the patient wears a sensor array which is attached to the abdominal skin and a data recorder for storage of the information generated by the ingested capsule. After the examination the data are downloaded into the Given Imaging workstation and a video is generated.
