Evaluation C-Scan System in Providing Structural Information and Polypoid Lesions in the Colon of Healthy Subjects

During C-Scan procedure the subject swallows the C-Scan cap. The capsule travels painlessly through the gastrointestinal tract, seeking polyps, the precursors of colorectal cancer. It is essential to increase the stool's contrast by ingesting radio-opaque material. During the passage of the capsule in the gastrointestinal tract, it transmits information to a recorder attached to the back. In order to collect data about the instantaneous localization of the capsule traveling in the colon additional sensors are embedded in the recorder on the back side. After the capsule is expelled, the data from the recorder is downloaded to an acquisition workstation. Later, the data is transferred to a processing workstation where dedicated software visualizes and analyses the data.
