Abstract

I. Graesslin, U. Katscher, F. Schweser, M. Niemann, P. Börnert Philips Research Laboratories, Hamburg, Germany Introduction Due to the analogy between the design of spatially selective RF pulses and MR imaging [1], it is possible to adapt the methodology of parallel imaging [2, 3] for parallel transmission [4-6]. Thus, the RF pulse calculation can be performed via direct matrix inversion [4-6], which in parallel imaging has been used by, e.g., [2, 3]. On the other hand, the RF pulse calculation of parallel transmission might be performed via iterative methods [7, 8], which in parallel imaging has been used by, e.g., [9]. This paper discusses the iterative approach in some detail and compares the two approaches with respect to their running times for different scenarios.
