3D Computed Tomography (CT) is a nondestructive scanning technology that allows you to view and inspect the external and internal structures of an object in 3D space. Computed Tomography works by taking hundreds or thousands of 2D Digital Radiography projections around a 360 degree rotation of an object. Algorithms are then used to reconstruct the 2D projections into a 3D CT volume, which will allow you to view and slice the part at any angle.
The same technology allows medical doctors and dentists to more accurately diagnose their patients and/or to view implants.
In the course of developing sophisticated imaging techniques for peering into the human body, radiologist Dr. Kai-Hung Fung discovered something within himself: an artist.
Dr. Fung is a specialist in diagnostic radiology at Pamela Youde Nethersole Eastern Hospital, Hong Kong SAR, China. The discovery happened when Fung was asked by surgeons to generate 3-D images to allow them to visualize complex anatomies prior to surgery. Beginning with CT scans that show slices of organs at different depths, Fung stacked the slices into a single image and developed a way to indicate changes in depth with contour lines similar to those on a topographic map.
Dr. Fung has used a post-production trick he developed, known as the “rainbow technique” to add colored contour lines to his images. This enhances the 3D effect.
His approach to radiology doesn’t stop with medical imagery. He has partnered with Dr. Gary Yeoh to produce 3-D CT images of flowers and biological specimens.
Dr. Fung’s art career has blossomed. His amazing diagnostic images have been awarded, exhibited and published. His CT and MR scans are more than just psychedelic images, they are “4-D visualizations” that help surgeons visualize the changing perspectives and relative relationships of various anatomical structures.
