摘要: The authors describe a method for accurate in vivo multislice imaging of the active component B1 field which is based on previously proposed method, uses signal intensity ratio two images measured with different excitation angles, and repetition time TR 5 > or = T1. new essentially reduces scan by means an additional compensating pulse. suppression T1 effects this pulse are verified simulations measurements. Further investigations concerned influence slice selective magnetization transfer to determination. stability accuracy presented shown several phantom With described can be determined 23 cross-sections less than 6 min.
