Radiologist Kai-hung Fung makes beautiful and informative art from the CT (computed tomography) scans of his patients, digitally manipulating them to look more appealing. His image of the inside of our sinuses won the 2007 International Science and Engineering Visualization Challenge

'What lies behind our nose?'

This is the winning image of the 2007 International Science and Engineering Visualization Challenge.

The original CT scan was taken from a 33-year-old Chinese woman who came in to have her thyroid examined.

The 3D image is digitally reconstructed from many millimetre-thick 2D X-ray "slices" taken in the CT scanner. 182 slices are stacked together here, allowing us to look upward at her nasal passages from beneath her head.

The bones, soft tissue and fat have been removed from the image, leaving just the cast of the sinuses.

'Network'

This image looks directly down through the top of the patient's head.

The complex network of arteries and veins in the brain can be seen in shades of dark blue and the skull base is shown in green in the background.

'Sound track'

This is the inside of a human ear canal.

The two tiny bones hanging down the ear canal, shown in blue, help to transmit sound from the ear drum to the inner ear.
