title = "SAR in parallel transmission",
abstract = "Parallel transmission bears the potential of compensating B1 field inhomogeneities induced by wave propagation effects in (ultra) high field whole body MR imaging. However, with increasing field strength, the RF power deposition and the associated local specific absorption rate (SAR) represent an important attention point with respect to patient safety. This paper presents simulations of a 3T whole body eight-channel transmit/receive body coil loaded with a human bio-mesh model. Phantom SAR simulations were carried out and validated by temperature measurements. A good correlation between SAR simulations and measured temperature was obtained, so that the FDTD method can be considered to be a valuable tool in determining (local) SAR for patient safety in multi-channel transmission MRI systems.",
