We have generated a numerical model of a 64-channel receive array at 7T and analysed its influence on SAR on an 8-channel transmit array. Simulations were conducted using a finite integration technique in CST Microwave Studio to create a model of the combined Tx/Rx system on both our phantom and the Duke human body model. Each receive element was actively detuned and implemented within our 8 channel transmit array model to provide us with an improved model from which we found that there was a negligible effect on the B1+ field and a reduction in the SAR of ~20%.
