“…Like shell rendering, the shear-warp method can be used in both surface and volume mode. The speed of its surface mode is about the same as that of shell rendering in surface mode, but its volume mode is faster (about 2 times) than shell rendering [51], although the shear-warp method requires about 6-8 times more storage space than shell rendering. We have developed a new method, called shear-warp shell rendering, which combines the advantages of both methods [51] to achieve the speed of shear-warp and storage efficiency close to that of shell rendering.…”

“…These are more difficult to parallelize and implement than Type 1 operations. Examples of such operations are various surface and volume rendering methods, particularly those that use some sort of a front-to-back or back-to-front splatting/projection strategy, such as shell and shear-warp rendering methods [46,49,50,51]. We label those CAVA operations, which require each slice/chunk to be accessed more than once to complete the operation as Type 3.…”

The Medical Image Processing Group (MIPG) at the University of Pennsylvania has been developing and distributing medical image analysis and visualization software systems for a long period of time. Our most recent system, 3DVIEWNIX, was first released in 1993. Since that time, a number of significant advancements have taken place with regard to computer platforms and operating systems, networking capability, the rise of parallel processing standards, and the development of open source toolkits. The development of CAVASS by our group is the next generation of 3DVIEWNIX. CAVASS will be freely available, open source, and is integrated with toolkits such as ITK and VTK. CAVASS runs on Windows, Unix, and Linux but shares a single code base. Rather than requiring expensive multiprocessor systems, it seamlessly provides for parallel processing via inexpensive COWs (Cluster of Workstations) for more time consuming algorithms. Most importantly, CAVASS is directed at the visualization, processing, and analysis of medical imagery, so support for 3D and higher dimensional medical image data and the efficient implementation of algorithms is given paramount importance. This paper focuses on aspects of visualization. All of the most of the popular modes of visualization including various 2D slice modes, reslicing, MIP, surface rendering, volume rendering, and animation are incorporated into CAVASS.

The Medical Image Processing Group (MIPG) at the University of Pennsylvania has been developing (and distributing with source code) medical image analysis and visualization software systems for a long period of time. Our most recent system, 3DVIEWNIX, was first released in 1993. Since that time, a number of significant advancements have taken place with regard to computer platforms and operating systems, networking capability, the rise of parallel processing standards, and the development of open source toolkits.

Computer Aided Visualization and Analysis Software System (CAVASS) is an open-source software system that is being developed by the Medical Image Processing Group (MIPG) at the University of Pennsylvania. CAVASS is freely available, open source, integrated with popular toolkits, and runs on Windows, Unix, Linux, and Mac OS. It includes extremely efficient of the most commonly used image display, manipulation, and processing operations. Parallel implementations of computationally demanding tasks such as deformable registration are provided as well using the inexpensive COW (Cluster of Workstations) model. CAVASS also seamlessly integrates and interfaces with ITK and provides a graphical user interface for ITK as well. CAVASS can easily interface with a PACS by directly reading and writing medical images in the industry standard DICOM format and can also input and output other common image formats as well. We describe the key features, general software architecture, interface with ITK, parallel architecture, and the CAVASS build and test environment. New stereo rendering capabilities are described as well.
