Abstract
A magnetic resonance imaging method involves acquisition of sets of magnetic resonance signals from several scan-volumes of an object. According to the invention different spatial approaches are taken in the scanning of the respective scan-volumes. In particular_respective scan-volumes include different numbers of scan-slices or scan slices of respective scan-volumes have different slice-thickness or scan-slices of respective scan-volumes have different fields-of-view or scan-slices of respective scan-volumes have different numbers of scanned points in k-space.

A magnetic resonance imaging method comprising the steps of:
- acquisition of sets of magnetic resonance signals from several scan-volumes of an object, wherein based upon characteristics of portions of the object to be analyzed, said portions corresponding to respective scan-volumes, a particular spatial approach of analysis of each respective scan-volume is employed, and wherein the k-space of the scan-volumes are scanned in accordance with characteristics of the portion of the object to be scanned for acquiring the magnetic resonance signals from the respective scan-volumes.
A magnetic resonance imaging system comprising:
- a receiver system for receiving sets of magnetic signals from several scan-volumes of an object, and
- a scanning system for scanning the scan-volumes, wherein
- the scanning system is arranged such that a particular spatial approach of analysis of a portion of the object, said portion corresponding to a respective scan-volume, is employed based upon characteristics of the respective scan-volume to be analyzed.
A computer program embodied on a computer-readable medium for magnetic resonance imaging comprising:
- computer readable program code means for, receiving sets of magnetic resonance signals from several scan-volumes of an object, and
- computer readable program code means for, based upon characteristics of a portion of the object to be analyzed, said portion corresponding to a respective scan-volume, a particular spatial approach of analysis of the respective scan-volume is employed.
