Abstract: This paper presents a fast maximum intensity projection technique based on binary shear-warp factorization. The proposed method divides the density domain into a small number of intervals, and to each interval a binary code representation is assigned. In a preprocessing step, an additional volume is created which contains for each voxel the code of the interval enclosing the given voxel density. We present an appropriate data structure for storing this volume and an efficient lookup table technique which can be used to rapidly access a voxel of a certain density code. The volume is efficiently resampled along viewing rays only in voxels where the densities reside in the interval which contains the appropriate maximum value.
