A “Holographic” Display Test bed for Visualization of Digital 3D Data from Medical Applications Recent years have seen rapid technological development within diagnostic imaging and other medical applications using visual information. Standard medical imaging technologies such as CT, MR and 3D ultrasound all generate 3D volume data sets. Over the last years there has been a rapid development on improved presentations on high resolution 2D screens. By using these methods, radiology departments can handle more patients with the same staff; improve diagnosis, patient safety and quality of care.
