A system for visualizing a 3D volume, represented by a 3D data set stored in a memory (890) as contiguous 2D slices with successive depths. A memory cache 895 provides faster access to part of the data set. A processor 860 creates a 2D representation of the volume by casting an imaginary bundle of n₁×n₂parallel rays through the 3D volume onto a corresponding rectangle of n₁×n₂ pixels. Each time sequentially n₃ samples are determined for each ray, giving a sequence of bundle blocks of each n₁×n₂×n₃ samples. An interpolation function is used to determine a 3D set of voxels contributing to the bundle block. The size of the bundle block is chosen such that the determined set of voxels fits into the cache. The set of voxels is then sampled from the cache.
