Visualization of volumetric multicomponent data sets is a high-dimensional problem, especially for color data. Medical 3D ultrasound (US) technology has rapidly advanced during the last few decades and scanners can now generate joint 3D scans of tissues (B-mode) and blood flow (power or color Doppler) in real time. Renderings of such data sets have to(More)
Opacity transfer function (OTF) generation for direct volume rendering of medical image data is an intensely discussed subject. Several automatic methods exist for CT and MRI data, which are not apt for ultrasound data, mainly due to its low signal-to-noise ratio. Furthermore, ultrasound (US) imaging is able to produce time-varying 3D datasets in real time(More)
Acknowledgment The authors would like to acknowledge the contributions of Armin Schoisswohl of GE Medical Systems Kretztechnik, Zipf, Austria, in providing the 3DUS data sets and valuable discussions. Abstract Sometimes real world data exhibits characteristics cumbersome to model. If so, segmentation turns out to be a tricky task. This is especially true(More)
