Abstract

In this paper, we present a new approach to the generation and manipulation of oblique slices of MR/CT or any voxel space images. We consider the result of the voxel space as if it would be cut by a scalpel, simulating the action of a surgeon. With the intervention of a new definition of discrete 3D voxel plane, we show that this can be done in a highly efficient way and that there are very few computations to do. It is shown that the supercover of the continuous oblique plane is a 6-connected discrete plane that has many very interesting properties that can be usefully exploited. For instance, geometrical considerations avoid much of the intersection computations and once one oblique slice is generated, all the other parallel oblique slices can be generated with few further computations. These results are applied to improve the existing algorithms and provide some ideas for new ones. It should also improve the handling possibilities of oblique slices, indeed, almost all that can be done on a sagittal or axial slice can then also be done on oblique slices. An extension to 4D oblique slices is possible.
