Case Study: Observing a Volume Rendered Fetus within a Pregnant Patient

Augmented reality systems with see-through headmounted displays have been used primarily for applications that are possible with today's computational capabilities. We explore possibilities for a particular application--in-place, real-time 3D ultrasound visualization--without concern for such limitations. The question is not "How well could we currently visualize the fetus in real time," but "How well could we see the fetus if we had sufficient compute power?" Our video sequence shows a 3D fetus within a pregnant woman's abdomen--the way this would look to a HMD user. Technical problems in making the sequence are discussed. This experience exposed limitations of current augmented reality systems; it may help define the capabilities of future systems needed for applications as demanding as real-time medical visualization.
