Effects of Tuning Condition, Head Size and Position on the SAR of a 9.4T Dual Row Array

Mikhail Kozlov¹, Gunamony Shajan², Robert Turner¹

For an already constructed 9.4T dual row array, excited in CP and other transmit modes, we investigated peak SAR averaged over 10 grams (SAR10g) for different tuning conditions, and different head positions with three scaling factors. For a given array, the tuning condition significantly affected SAR10g, while the influence on SAR10g of head position and scaling factor was relatively small.
