New technology is bringing the power of augmented reality into clinical practice.

The system, called ProjectDR, allows medical images such as CT scans and MRI data to be displayed directly on a patient’s body in a way that moves as the patient does.

“We wanted to create a system that would show clinicians a patient’s internal anatomy within the context of the body,” explained Ian Watts, a computing science graduate student and the developer of ProjectDR.

The technology includes a motion-tracking system using infrared cameras and markers on the patient’s body, as well as a projector to display the images. But the really difficult part, Watts explained, is having the image track properly on the patient’s body even as they shift and move. The solution: custom software written by Watts that gets all of the components working together.

ProjectDR was presented last November at the Virtual Reality Software and Technology Symposium in Gothenburg, Sweden.
