Radiologist Kai-hung Fung has a rather strange, yet very interesting and unique hobby. He turns 3D computed tomography scans into art, by adding colour using something he calls "rainbow technique".

However, Fung doesn't really edit the photos and make any changes in image processing software, apart from adding colour, of course.

"The pictures I create are generated directly from the medical 3D workstation, representing what I see on it. I do not use software such as Adobe Photoshop to further change the image," said Fung. "My aim is to preserve the direct relationship between the data and the artwork. It is a true integration of art, science and technology and can be studied both scientifically and enjoyed as a visual art."

Fung's work has generated quite a bit of attention on the art scene, and its now showing in a number of galleries across the world. Unlike most money grabbing doctors I've had the misfortune of meeting, Fung is a truly altruistic soul, and he donates all proceeds from sales of his pieces to charity. What a nice chap.
