Computer-aided detection for CT colonoscopy

27 March 2007

Torino, Italy. CADCOLON im3D is a computer aided detection (CAD) system from iM3D SpA designed to support radiologists' diagnoses of suspect polyps in the colon and rectum, using high and low dose CT.

The system combines advanced virtual colonoscopy features with powerful detection algorithms that are able to detect and highlight suspect areas in an accurate, simple and user-friendly way.
The system loads data from a CT scan and creates a three dimensional model of the patient's colon. The CAD technology then detects suspect areas highlighting and classifying them according to their shape and intensity attributes.

A range of tools and features allows the radiologist to navigate around the reconstruction of the colon, measure specific areas, tag them, take screen shots or add comments and notes. At the end of the examination, the system goes through each area previously highlighted, allowing the physician to choose comments and images to be published into the final report. At the end of this review the system creates a document that can be saved or printed according to user preferences.

An additional feature is electronic cleansing during the active analysis process. This allows for a better examination of wall surface sections in presence of faecal deposits and irregular conformations.
