Magnetic resonance system and method for control thereof
A method to control a magnetic resonance system includes at least one protocol step for measurement data acquisition with the magnetic resonance system, and at least one operator interaction step which allows an operator to enter information that affects at least one subsequent step in the control of the magnetic resonance system.
1. A method for controlling a magnetic resonance system, comprising:
in order to execute a data acquisition procedure to acquire magnetic resonance data from a subject in a magnetic resonance data acquisition unit from a control unit connected to the magnetic resonance data acquisition unit, entering, via a user interface in communication with said control unit, at least one operating protocol that defines a plurality of successive protocol steps that forms said data acquisition procedure;
in said at least one operating protocol, including at least one operator interaction step that is then built into said at least one operating protocol to occur at a predetermined time, among said plurality of successive protocol steps, during execution of said data acquisition procedure;
beginning execution of said data acquisition procedure from said control unit by operating the magnetic resonance data acquisition unit according to said operating protocol;
when said operator interaction step occurs in said operating protocol, interrupting said execution of said data acquisition protocol and displaying, at said user interface, at least one operator interaction field allowing an operator to make an entry in said operator interaction field that affects subsequent protocol steps in said operating protocol; and
after said operator makes said entry in said operator interaction step, controlling protocol steps in said operating protocol, that occur subsequent to said operator interaction step, from said control unit dependent on said entry.
2. A method as claimed in claim 1 wherein said operator interaction step comprises a planning step that allows, as said entry in said operator interaction field, an adjustment of data acquisition parameters in at least one of said protocol steps following said planning step.
3. A method as claimed in claim 1 wherein said operator interaction step comprises an evaluation step that allows, as said entry in said operator interaction field, an evaluation algorithm to be initiated by an operator to evaluate measurement data acquired in at least one of said protocol steps preceding said evaluation step to obtain an evaluation result, and to allow adjustment by the operator of data acquisition parameters for at least one of said protocol steps following said evaluation step, dependent on said evaluation result.
4. A method as claimed in claim 1 wherein said operator interaction step comprises a decision step allowing, as said entry in said operator interaction field, entry of an indication representing a decision by an operator with respect to said further execution of said procedure.
5. A method as claimed in claim 4 wherein said decision step comprises allowing the operator to add at least one additional protocol step to said plurality of protocol steps.
6. A method as claimed in claim 1 comprising allowing an operator to freely insert said operator interaction step, via said user interface, between any successive two of said protocol steps after entering said operator protocol into said control unit.
7. A method as claimed in claim 6 comprising, in addition to insertion of said operator interaction step, allowing an operator to insert a pause step in said data acquisition procedure.
8. A method as claimed in claim 1 comprising embodying said at least one user interaction step in said at least one operating protocol before entry of said at least one operating protocol into said control unit.
