Abstract
A computer implemented method of generating a succession of two-dimensional image frames for a slab cine multi-planar reformatting (MPR) process by advancing a slab through a volume defined by a volume data set, including receiving a volume data set defining a volume; specifying a view axis with respect to the volume; advancing a slab through the volume along the view axis in incremental step sizes smaller than the slab thickness; and determining at each slab position an MPR view by: selecting a plurality of sample points along each of a plurality of rays cast through the slab, and performing a projection of the sample points on to an image plane using an a projection function, wherein at least some of the sample points used for the overlap region are re-used from the previous slab position.
