An MRI apparatus is provided. The apparatus includes a main magnet for
generating a main magnetic field in an examination region, a plurality of
gradient coils for generating gradient fields within the main field, an
RF transmit coil for transmitting RF signals into the examination region
and exciting magnetic resonance in a subject disposed therein in
accordance with a plurality of imaging parameters, the transmitted RF
signals having a SAR associated therewith, and a SAR processor for
maintaining the transmitted RF signals below a prescribed SAR level.
