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
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
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.
