METHOD AND DEVICE FOR SELECTING BODY MODEL POSITIONS FOR SAR MONITORING OF A MAGNETIC RESONANCE TRANSMIT ARRAY |
摘要 |
In a method and a device for specific absorption rate monitoring in a magnetic resonance system wherein multiple transmit coils are independently charged with respective currents, a primary model point voxel and at least one auxiliary model point voxel are automatically selected from among multiple voxels that model a modeled examination subject. The primary model point voxel is that voxel in which an absolute maximum of a total field variable occurs that is produced by the respective electrical fields emitted by the transmit coils. The at least one auxiliary model point voxel is that voxel in which a relative maximum of the variable occurs. The primary model point voxel and the at least one auxiliary model point voxel are stored, and specific absorption rate monitoring of an actual examination subject in the magnetic resonance system is implemented during the acquisition of magnetic resonance data in respective voxels of the actual examination subject corresponding to the stored primary model point voxel and the stored at least one auxiliary model point voxel.
