Description

This invention consists of a novel display technique for CT colonography data. It is based on automatic generation of a midline trace (centerline) of the colon, followed by display of a sequence of images of the colon that follow this centerline, and display a small field of view centered on it and perpendicular to it. This allows the radiologist the benefit of always seeing the colon in cross-section, as if it had been straightened and sliced perpendicular to its long axis. Such a viewing technique should maximize the prominence of polyps sticking out into the lumen of the colon. This should result in faster reading times with less disruption of concentration, potentially yielding both time-saving, and improvements in accuracy.
