Magnetic resonance imaging method, involves calculating current specific absorption rate value for current magnetic resonance measurement using stored data and modifying planned parameters

摘要

The method involves conducting a current magnetic resonance measurement to obtain magnetic resonance data from a subject A data representing a time curve of a radio frequency stressing experienced by the subject is stored. A current specific absorption rate (SAR) value is calculated for the measurement using the stored data and planned parameters are modified to bring the current SAR value within a preset SAR limit. An Independent claim is also included for a magnetic resonance apparatus.
