  abstract =   "Volumes acquired for medical examination purposes are
               constantly increasing in size. For this reason, the
               computer’s memory is the limiting factor for visualizing
               the data. Bricking is a well-known concept used for
               rendering large data sets. The volume data is subdivided
               into smaller blocks to achieve better memory utilization.
               Until now, the vast majority of medical workstations use a
               linear volume layout. We implemented a bricked volume layout
               for such a workstation based on Java as required by our
               collaborative company partner to evaluate different common
               access patterns to the volume data. For rendering, we were
               mainly interested to see how the performance will differ
               from the traditional linear volume layout if we generate
               images of arbitrarily oriented slices via Multi-Planar
               Reformatting (MPR). Furthermore, we tested access patterns
               which are crucial for segmentation issues like a random
               access to data values and a simulated region growing. Our
               goal was to find out if it makes sense to change the volume
               layout of a medical workstation to benefit from bricking. We
               were also interested to identify the tasks where problems
               might occur if bricking is applied. Overall, our results
               show that it is feasible to use a bricked volume layout in
               the stringent context of a medical workstation implemented
               in Java.",
