20080246768 | Imaging Volume Data - A method and apparatus for generating a two-dimensional output image of a slab multi-planar reformatting (MPR) volume data set from a selectable view point and view direction is described. The method comprises factorising a view transform matrix into an intermediate transform matrix and a warp transform matrix. The intermediate transform matrix is such that voxels in the volume data set map to pixels in an intermediate image in which neighbouring voxels in a plane of the volume data set which is most parallel to tie plane of the output image are separated by an integer number of pixel along each of tie axes of the intermediate image. The intermediate transform matrix is applied to the data set to provide an intermediate data set. A projection of the intermediate data set along the view direction is performed according to a desired projection algorithm to provide the intermediate image. The wrap transform matrix is then applied to the intermediate image to provide the output image. | 10-09-2008 |
