Abstract
A prescan is automated to the greatest extent practicable, allowing acquisition of a favorable image irrespective of skills of an operator, as well as minimizing the time related to the prescan. For a plurality of image types in imaging tasks, a comprehensive FOV including all FOVs respectively of a plurality of image types is set, and for the comprehensive FOV, it is determined whether or not an item adjusted by the prescan satisfies an allowable condition for each image type, and the prescan is executed to make an adjustment appropriate for the image type with the strictest condition, on the item not satisfying the allowable condition.
Claims15
A magnetic resonance imaging apparatus comprising,
- an imaging unit configured to acquire an NMR signal according to a predetermined imaging sequence,
- a processing unit configured to process the NMR signal acquired by the imaging unit, and
- a control unit configured to control operations of the imaging unit and the processing unit, wherein
- the control unit comprises,
- an accepting unit configured to accept one or more types of imaging tasks,
- an adjustment item determiner configured to determine an adjustment item necessary for executing the imaging task accepted by the accepting unit, and
- a prescan condition setter configured to set a prescan condition including execution or non-execution of a prescan based on a result of the adjustment item determiner, and
- the control unit controls the imaging unit so as to perform the prescan and the imaging task, according to the prescan condition determined by the prescan condition setter.
A control method of a magnetic resonance imaging apparatus for executing a prescan as advance imaging adjustment, automatically or semi-automatically, comprising,
- setting a comprehensive FOV including FOVs of respective image types in a plurality of imaging tasks,
- determining whether or not an item to be adjusted by the prescan satisfies a condition allowable for each image type in the comprehensive FOV, and
- controlling to execute the prescan on the item not satisfying the allowable condition, so as to make an adjustment that is appropriate for the image type with the strictest condition.
A computer-readable storage medium storing a control program of a magnetic resonance imaging apparatus for causing a computer to execute a process comprising,
- setting a comprehensive FOV including FOVs of respective image types in a plurality of imaging tasks,
- determining whether or not an item to be adjusted by the prescan satisfies a condition allowable for each image type in the comprehensive FOV, and
- listing items not satisfying the allowable condition, and
- setting a prescan condition for making an adjustment of the item being listed, the adjustment being appropriate for the image type with the strictest condition.
