Abriss: Voreen is an open source volume rendering engine which allows interactive visualization of volumetric data sets with high flexibility when integrating new visualization techniques. It is designed with minimal overhead, so that, even for difficult processing networks, high rendering speeds can be achieved. While Voreen is well-equipped to display Cartesian volumes, volumes in polar coordinates, such as raw ultrasound beam data, have to be interpolated and converted to Cartesian coordinates to be displayed. This is highly time-consuming on a CPU while interpolation and volume rendering can be done on a graphics card in real-time. We have added the functionality to display volumetric data in polar coordinates, where the volume is sampled along rays with a common center point and two angles of direction. Raycasters for 3d ultrasound volumes have been implemented as Voreen processors. In this way they can be used inside the Voreen framework and combined with other processors of the framework. We have also implemented a TCP/IP volume source which can receive volumetric streaming data via Ethernet and provide it to Voreen. In this way the visualization of live ultrasound data becomes possible. Screening for Parkinson's disease has been identified as a possible application for our work. Physicians look for hyperechogeneic regions in the mesencephalon. This task is greatly simplified when the ultrasound volume is supplemented by an MRI scan which features much higher spatial resolution and clarity. To show the functionality of the extension we have created an application which displays a static MRI head volume and the output of a GE Vivid 7 Dimension 4D ultrasound station with interactive (>20fps) frame rates.
