Being the manner which improves the resolution of the image which is formed by the device null 3 dimensional graphics data set which improves the resolution of manner
A bandlimited 3D image data set is interpolated before being projected onto a 2D image plane to improve image resolution. The 3D MRA image data set is divided into subvolumes which are separately interpolated and projected onto the 2D image plane. Interpolation is accomplished using a discrete cosine transformation ("DCT"), zero-filling to extend the transformed subvolume and inverse transforming the zero-filled subvolume.
