Fusion of multiple imaging planes for isotropic imaging in MRI and quantitative image analysis using isotropic or near-isotropic imaging
First Claim
1. A method of improving the resolution of medical images using a computer processing system comprising:
- obtaining a first image set of a body part relative to a first plane, the first image set comprising a first image data volume, the first image data volume having at least a first planar resolution parallel to the first plane, and a first perpendicular resolution along an axis perpendicular to the first plane, the first perpendicular resolution being less than the first planar resolution;
obtaining a second image set of the body part relative to a second plane that is different from the first plane, the second image set comprising a second image data volume;
using the computer processing system to convert the second image data volume to a common coordinate system with the first image data volume; and
combining the first and second image data volumes to form a resultant image data volume having a higher image resolution than the image resolution of the first image data volume.

Abstract
In accordance with the present invention there is provided methods for generating an isotropic or near-isotropic three-dimensional images from two-dimensional images. In accordance with the present invention the method includes, obtaining a first image of a body part in a first plane, wherein the first image generates a first image data volume; obtaining a second image of the body part in a second plane, wherein the second image generates a second image data volume; and combining the first and second image data volumes to form a resultant image data volume, wherein the resultant image data volume is isotropic or near-isotropic.
