Virtual Colonoscopy

with one comment

Virtual Colonoscopy is a relatively new field in radiology. Colonscopy was a very unpleasant experience before, in which the physician passed a camera on a flexible tube through the anus. Today this can be done in the radiology department with a xray-scan of the colon (without penetrating the body).

This week I visited some application specialists at Philips in Best. They showed me how a virtual colonoscopy works. All data for the 3D model was acquired during a body scan of the patient. I was impressed by the visualization. It is basically a flight through the colon, but you can see in all directions at the same time. This makes it possible to look behind corners and ledges without changing the viewing direction.

Here you can see a screenshot and the cube on the right is showing all 6 viewing directions (I marked it accordingly on the screenshot of the colonoscopy).
