Analysis of Artifacts Found in Endographic Visualization of Spiral CT Scans. PURPOSE: Analysis of patterns and causes of artifacts found in endographic visualization of spiral CT data. MATERIALS AND METHODS: A straight perspex tube with a diameter of 20 mm was scanned in three different positions with ten scan protocols of varying table feed, increment, kernel, and signal to noise ratio (Tomoscan AVE, Philips). The resulting 30 CT datasets were visualized as a virtual endoscopy (VE) with ten different visualization protocols (Easy Vision 4.2, Philips) of varying threshold, resolution, and perspective angle. 300…
