Title
Augmented Reality Visualization of Ultrasound Images: System Description, Calibration, and Features
Abstract
We developed a system for augmented realityvisualization of ultrasound images. This system is basedon our earlier "augmented workspace" setup.The user wears a custom video-see-through head-mounteddisplay (HMD). Two color video camerasattached to the HMD provide a stereo view of the scene.A third head-mounted video camera is added for tracking.A set of markers is attached to the ultrasound transducer;a set of stationary markers can be positioned above theworkspace. The system runs at the full 30Hz video framerate with a latency of about 0.1 sec, generating a stableaugmentation with no apparent jitter visible in thecomposite images. Three SGI Visual Workstationsprovide the computing power for the system.In this paper we describe the details of the system, itscalibration with a configuration of optical markerspartially immersed in a water bath, and some systemfeatures like spatiotemporal freezing and 3D targetlocalization that promise to be helpful for practicalapplications.
