APPARATUS AND METHOD FOR PLANNING MAGNETIC RESONANCE IMAGING
First Claim
1. A magnetic resonance imaging method comprising:
- acquiring a sparse scout image having low resolution;
reformatting the sparse scout image to generate one or more reformatted images having different coordinate systems;
determining a diagnostic imaging coordinate system based on the sparse scout image and the one or more reformatted images; and
acquiring one or more diagnostic images using space-encoding magnetic field gradients aligned with respect to the diagnostic imaging coordinate system.

Abstract
A diagnostic imaging system includes a magnetic resonance imaging scanner (10) for imaging an organ of interest, a reformatting processor (70) for constructing reformatted images corresponding to a scout image in different coordinate systems, and a graphical user interface (62) for displaying acquired images and reformatted images to an associated user An imaging processor (60) causes the scanner (10) to acquire a base sparse scout image of an organ of interest in a standard coordinate system, causes the reformatting processor (70) to generate one or more reformatted images from the sparse scout image in coordinate systems other than the standard coordinate system, determines a diagnostic imaging coordinate system aligned with the organ of interest using the base sparse scout image and the one or more reformatted images, and causes the scanner (10) to acquire one or more diagnostic images of the organ of interest in the diagnostic imaging coordinate system.
