Method and control device to operate a magnetic resonance system

1. A method to operate a magnetic resonance system to acquire magnetic resonance image data of an examination subject, said magnetic resonance system comprising a plurality of subsystems and a control device that operates the subsystems, said method comprising the steps of:

prior to operating the subsystems from the control device to acquire diagnostic magnetic resonance data from the examination subject, operating at least one of the subsystems from the control device to implement an adjustment of said at least one of said subsystems for the subsequent diagnostic data acquisition;

in the adjustment of said at least one of subsystems, making use of an adjustment volume in said control device that is associated with the adjustment, said adjustment volume comprising at least a region of a body containing the examination subject;

through the control device, establishing markings within image data of the examination subject, said markings characterizing at least of a position and orientation of the examination subject, and a dimension of the examination subject; and

based on said markings, automatically determining, in said control device, a spatial occupation and extent of said adjustment volume to implement the adjustment of said at least one of said subsystems.

2. A method as claimed in claim 1 comprising, with said markings, marking anatomically significant features of the examination subject.

3. A method as claimed in claim 2 comprising, with at least some of said markings, marking anatomical landmarks of the examination subject.

4. A method as claimed in claim 1 comprising entering at least some of said markings through a user interface of said control device.

5. A method as claimed in claim 1 comprising, with said markings, marking anatomically significant features of the examination subject and determining said anatomically significant features automatically in said control device.

6. A method as claimed in claim 1 comprising providing said control device with an overview image comprising the examination subject, and making said markings in said overview image.

7. A method as claimed in claim 6 comprising providing at least two overview images of the examination subject to the control device showing respectively different views of slices of the examination subject, and making said markings in said at least two overview images.

8. A method as claimed in claim 1 comprising, in said control device, adapting said adjustment volume to contours of the examination subject.

9. A method as claimed in claim 1 comprising, in said control unit, identifying a standard adjustment volume defined specifically for said examination subject and, in said control device, adapting at least one parameter of said standard adjustment volume to the examination subject based on said markings.

10. A method as claimed in claim 1 comprising, in said control device, determining said at least one of said position and orientation of said examination subject, and said extent of said examination subject as different adjustment volumes for different adjustments of different subsystems, all based on said markings.

11. A method as claimed in claim 1 comprising using the heart of a patient, or a portion of the heart of a patient, as said examination subject.

12. A method as claimed in claim 11 comprising marking a longitudinal axis of a ventricle of the heart with at least one of said markings.

13. A method as claimed in claim 11 comprising marking a center point of a ventricle of the heart with at least one of said markings.

14. A control device to operate a magnetic resonance system to acquire magnetic resonance image data of an examination subject, said magnetic resonance system comprising a plurality of subsystems, said control device comprising:

a processor configured to operate at least one of the subsystems, prior to operating the subsystems from the control device to acquire diagnostic magnetic resonance data from the examination subject, to implement an adjustment of said at least one of said subsystems for the subsequent diagnostic data acquisition;

in the adjustment of said at least one of subsystems, said processor being configured to make use of an adjustment volume in said control device that is associated with the adjustment, said adjustment volume comprising at least a region of a body containing the examination subject;

an input to said processor configured to establish markings within image data of the examination subject, said markings characterizing at least of a position and orientation of the examination subject, and a dimension of the examination subject; and

said processor being configured, based on said markings to automatically determine spatial occupation and extent of said adjustment volume to implement the adjustment of said at least one of said subsystems.

15. A magnetic resonance system to operate a magnetic resonance system to acquire magnetic resonance image data of an examination subject, said magnetic resonance system comprising:

a plurality of subsystems;

a control device that operates the subsystems; and

said control device comprising a processor configured to operate at least one of the subsystems, prior to operating the subsystems from the control device to acquire diagnostic magnetic resonance data from the examination subject, to implement an adjustment of said at least one of said subsystems for the subsequent diagnostic data acquisition, in the adjustment of said at least one of subsystems, said processor being configured to make use of an adjustment volume in said control device that is associated with the adjustment, said adjustment volume comprising at least a region of a body containing the examination subject, an input to said processor configured to establish markings within image data of the examination subject, said markings characterizing at least of a position and orientation of the examination subject, and a dimension of the examination subject, and said processor being configured, based on said markings to automatically determine spatial occupation and extent of said adjustment volume to implement the adjustment of said at least one of said subsystems.

16. A non-transitory computer-readable storage medium encoded with programming instructions, said storage medium being loadable into a control and processing system of a magnetic resonance imaging system, and said programming instructions causing said control and processing system to:

prior to operating the subsystems from the control device to acquire diagnostic magnetic resonance data from the examination subject, operate at least one of the subsystems from the control device to implement an adjustment of said at least one of said subsystems for the subsequent diagnostic data acquisition;

in the adjustment of said at least one of subsystems, make use of an adjustment volume in said control device that is associated with the adjustment, said adjustment volume comprising at least a region of a body containing the examination subject;

establishing markings within image data of the examination subject, said markings characterizing at least of a position and orientation of the examination subject, and a dimension of the examination subject; and

based on said markings, automatically determine a spatial occupation and extent of said adjustment volume to implement the adjustment of said at least one of said subsystems.
