MRI apparatus and method for generating automatically positioned 2D slice images of heart tissue from acquired 3D heart image data
First Claim
1. A magnetic resonance imaging (MRI) apparatus comprising:
- an MRI gantry having MR image data acquisition and processing circuits including at least one computer and associated memory configured with executable computer programs which when executed by said CPU, operates to;
acquire three-dimensional first image data including a heart of a subject, said first image data including a plurality of cross-sectional two dimensional images that are parallel to;
detect a first axis relating to the heart from the acquired three-dimensional first imaging data;
generate a first generated image on a plane containing the first axis and a first vector passing through the first axis from the acquired first imaging data wherein resolution of the first generated image is higher than a predetermined resolution; and
detect a second axis relating to the heart from the acquired first image data based on the first generated image.

Abstract
First magnetic resonance imaging (MRI) three-dimensional heart image data includes a plurality of two-dimensional heart image data superimposed and having a resolution in at least one direction that is different from that in two other directions. A first axis is detected in the three-dimensional heart image data. A first vector is calculated as passing through the first axis and having at least a predetermined resolution and generated image data on a plane passing through the first axis and the first vector is generated from the first imaging data. A second axis is detected relating to the heart from the generated image data, the second axis being a higher precision axis than the first axis.
