Absorption distribution
The absorbed power distribution in a patient positioned in a 3 T MR system (gradient echo pulse, flip angle 90°, duty cycle 5%). The SAR values are shown in a false-colour scale ranging from 0 (blue) to 4.0 W/kg (red). (a) The SAR projected on the (right) arm and hand of a patient. (b) The SAR in a left-right plane. The SAR is highly determined by the distribution of fat, muscle and bone (bone is depicted in grey). Results taken from Van den Bergen et al. 2006, with permission.5
