A system and method for object-order reformatting of a volume having data slices includes a coordinate transformation unit for transforming coordinates of an oblique surface through the volume from image-order to object-order, an object-order slice traversal unit for traversing the slices in accordance with the object-order of the transformed coordinates, and a slice-pair interpolation unit for interpolating voxel values of a pair of adjacent slices to render pixel values for an image of the oblique plane.
