Method for in situ characterization of radiofrequency heating in parallel transmit MRI
Magnetic Resonance in Medicine, 07/05/2012
Alon L et al. – This study shows that the information needed to characterize radiofrequency (RF) heating in parallel transmission is contained within a local power correlation matrix. Building upon a calibration scheme involving a finite number of magnetic resonance thermometry measurements, this work establishes a way of estimating the local power correlation matrix.
