Abstract
One or more example embodiments of the present invention relates to a method for generating MR images of the heart, the method comprising acquiring and reconstructing a first set of 2D reference images of the heart during a reference heartbeat, the first set comprising a first reference image acquired along a first reference plane position thorough the heart and acquiring a second set of 2D images of the heart during a second heartbeat.
Claims20
A method for generating MR images of a heart, the method comprising:
- acquiring and reconstructing a first set of 2D reference images of the heart during a reference heartbeat, the first set comprising a first reference image acquired along a first reference plane position through the heart;
- and
- acquiring a second set of 2D images of the heart during a second heartbeat, the acquiring the second set including,
- acquiring a first image in the second set, the first image acquired along the first reference plane,
- determining, based on the first reference image and the first image in the second set, a first in-plane displacement of the heart in an image plane of the first reference plane position,
- determining a shifted plane position for a second image in the second set to be acquired perpendicular to the first image in the second set based on the determined first in-plane displacement, and
- acquiring and reconstructing the second image along the shifted plane position, wherein all images of the first set of 2D images and all images of the second set of 2D images are diagnostically relevant images.

An MR imaging system configured to generate MR images of a heart comprising:
- a control module is configured to cause the MR imaging system to,
- acquire and reconstruct a first set of 2D reference images of the heart during a reference heartbeat, the first set comprising a first reference image acquired along a first reference plane position thorough the heart and at least a further reference image acquired at a second reference plane position perpendicular to the first reference plane position, the further reference image representing a defined anatomical region of the heart,
- acquire a second set of 2D images of the heart during a second heartbeat, which includes,
- acquire a first image in the second set acquired along the first reference plane,
- determine, based on the first reference image and the first image in the second set, a first in-plane displacement of the heart in an image plane of the first reference plane position,
- determine a shifted plane position for a second image in the second set to be acquired parallel to the second reference plane position of the heart based on the determined first in-plane displacement, and
- acquire and reconstruct the second image along the shifted plane position, wherein all images of the first set of 2D images and all images of the second set of 2D images are diagnostically relevant images.
