Safety,Usability and Compliance of Using C-Scan System for Providing Information on Colonic Polypoid Lesions and Masses

Overall Design: Up to 45 healthy subjects will participate in this study. Subjects to be enrolled in this study are indicated and scheduled to undergo optical colonoscopy based on the following symptoms or by being classified as higher than average risk based on one or more of the following: * Surveillance - Significant findings in previous optical colonoscopy * Diagnostic - Polyps detected in virtual colonoscopy referred for polypectomy * Diagnostic - Polyps detected in previous optical colonoscopy (community setting) referred for polypectomy * Diagnostic - Positive FIT (Fecal Immunochemical Test) * Diagnostic - one or more of the typical symptoms: * abdominal pain * Change in bowel habits * Anemia or overt bleeding in stool * Significant weight loss * First degree relatives of CRC (Colo-Rectal Cancer)subjects Alternatively, average risk based on their age and demographics referred for screening for polyps Each subject will receive a comprehensive explanation regarding the study nature. During this process, and per ethical committee approval, subjects may be asked several questions (over the phone) regarding their medical background for preliminary assessment of eligibility. Once informed consent is obtained, a thorough evaluation of subject's eligibility will be performed based on inclusion / exclusion criteria. Eligible subjects will be required to undergo FIT procedure, per package insert instructions, within pre-defined timelines. All subjects will be scheduled to undergo capsule procedure, to be followed later on with optical colonoscopy procedure. One to three days following end of C-Scan procedure the subjects will be contacted by phone by the clinical coordinator to follow-up on the subject well-being. Same follow-up procedures will be applied one to three days following Optical Colonoscopy procedure. Medical history and concomitant medication information will be collected for all subjects. Study Duration: The duration of study participation for each subject is expected to be approximately 8-10 weeks. The total study duration across all patients is expected to be approximately 6 months, dependent upon subject recruitment rate. C-Scan Procedure: Subjects will be instructed to skip breakfast or lunch on the day of C-Scan Capsule ingestion to expedite gastric passage. Liquids are allowed. The subjects will be connected to the C-Scan Track and after successful system's activation (BIT - built in test), the subject will be asked to ingest the C-Scan Capsule with some water, contrast media (GE Omnipaque 350) and non-soluble fiber, in the presence of a physician investigator or designee. The subject will also be provided with an RF watch. A representative of the sponsor will attend the ingestion procedure, as needed to assure proper activation. Post ingestion, the subject will receive detailed instructions about the daily routine and activities as well as use of the RF watch and then will be discharged home with written instructions on the procedure Instructions for use (IFU), daily diary, FIT kit and capsule return kit. FIT Procedure: All subjects will be required to perform FIT procedure using \[OC-Light\] FIT Kit prior or during the capsule procedure Capsule Return: Capsule procedure is completed upon capsule excretion or system auditory indication of 'End of Procedure'. Subjects will be instructed to inform the study coordinator or designee upon capsule excretion
