Ultrafast B1 mapping with RF‐prepared 3D FLASH acquisition: Correcting the bias due to T1‐induced k‐space filtering effect

Purpose The traditional radiofrequency (RF)‐prepared B1 mapping technique consists of one scan with an RF preparation module for flip angle‐encoding and a second scan without this module for normalizing. To reduce the T1‐induced k‐space filtering effect, this method is limited to 2D FLASH acquisitio...
