Three-Dimensional Photography Assisting Plastic Surgeons

Research from the College of Medicine indicates that three-dimensional (3D) photography can help plastic surgeons plan surgery and measure its outcomes.

"This photography accurately records the problem, identifies areas of reconstruction, and shows results. It is an excellent tool for data acquisition," explains Donald MacKay, M.D., associate professor of surgery and pediatrics, and acting chief of plastic surgery at Hershey Medical Center.

This experimental, portable system being used by MacKay and his team consists of a digital camera to capture an image as a separate flashlight projector casts a light pattern over the subject. A second digital camera is used to obtain a color, textured image of the subject. Both images are obtained with just one exposure.

The images are then downloaded to a computer, which generates the three-dimensional picture. Pre- and post-operative images are stored in a database. Digital storage will allow an easy comparison of changes in volume and shape over time.

"We are able to put the images on a computer within a few minutes. Having this pre-operative data helps with surgical planning and is also an excellent educational tool. Post-op images are used to assess outcomes," says MacKay.
