 Abstract: To achieve a sufficient dynamic range for single channel B1+ mapping required for calibration of multi-channel transmit arrays two distinct solutions have been suggestion recently: (1) Bloch-Siegert effect based B1+ mapping and (2) B1+ mapping using linear combinations of transmit channels. In this work, both approaches are combined and interferometric Bloch-Siegert B1+ mapping is introduced. This approach is cross-validated against two recently introduced interferometric B1+ mapping methods based on actual flip angle imaging (AFI) and a multi flip-angle pre-pulse method as well as against single-channel AFI based B1+ mapping.
