Method for enhanced voxel resolution in MRI image |
摘要 |
<p>A method for providing an enhanced 3-D image for a volume imaging apparatus obtains 3-D volume images of an object at a first resolution and forms a 3-D matrix of voxels at a second, higher resolution. Two or more 3-D volume images that have different spatial orientations and that intersect at the voxel are registered. The voxel is mapped to the 3-D matrix. Inpainting fills in gap regions between mapped voxels in the 3-D matrix. A simulated first-resolution data value is generated according to one or more 3-D matrix values. The simulated first-resolution data value is compared with an observed first-resolution value from the 3-D volume images and, until the simulated first resolution data value is within a predetermined threshold value of the observed first-resolution value or until a predetermined number of iterations is reached, the 3-D matrix voxel values are adjusted and the simulated first-resolution data value recomputed.</p> |
