METHOD AND IMAGING APPARATUS FOR POSITIONING A PATIENT SLICE FROM WHICH IMAGE DATA ARE TO BE ACQUIRED

摘要

In a method for slice positioning of an examination subject in a magnetic resonance system an item of localization information describing the arrangement of the examination subject is automatically determined at least one item of alignment information is automatically determined. At least one slice positioning entry is acquired by an operator, which includes a selection of one of the items of alignment information or an item of manual positioning information. Offset information, which includes a relative slice positioning effected by the manual positioning information, is automatically determined and the slice positioning is determined as a function of the slice positioning entries and the offset information. The offset information is stored separately from the slice positioning in a magnetic resonance measurement protocol, and is used in a further configuration of a further slice positioning.

1. A method for positioning a slice within an examination object from magnetic resonance (MR) data are to be acquired with an MR apparatus comprising an MR scanner, said method comprising:
in a processor, automatically determining localization information that describes and arrangement of the object in the MR scanner with respect to a reference position; in said processor, automatically determining at least one item of alignment information from the localization information, with positioning information being individually assigned by the processor to a respective examination region of the object, with each item of alignment information comprising an item of positioning information for a slice in the respective examination region; manually making at least one slice positioning entry into said processor that includes an item of manual positioning information describing a manual positioning of the object in the MR scanner; in said processor, automatically determining offset information dependent on said at least one slice positioning entry, said offset information including a relative slice positioning of said slice effected only by said manual positioning information, with respect to said reference position; in said processor, automatically determining positioning of the object in the MR scanner dependent on said at least one slice positioning entry and said offset information in order to operate the MR scanner to acquire MR data from the slice; electronically storing the offset information separately from the positioning of the object, in a magnetic resonance measurement protocol in a form that is retrievable to automatically operate the MR scanner, using the magnetic resonance measurement protocol, to acquire said MR data from said slice; and in a different acquisition of MR data for a different slice in the object, separately retrieving the offset information and using the retrieved offset information to configure a different slice positioning for said different slice in said different MR data acquisition.
