Improving B1-uniformity by calibration procedure is crucial for the pTx imaging and commonly individual B1 coefficient estimation is conducted in the beginning of each patient scan protocol. However, B1 calibration procedure increase the scan time by approximately 10~15 mins increasing discomfort to the patient. Here we propose using global B1 coefficient template to reduce scan time while maintaining acceptable B1 profile. The approach using global B1 coefficient template is assumed to have limited inter-individual variation of B1 coefficient between subjects. We demonstrate the feasibility of scan with global B1 coefficient template and provide a perception of in-vivo scan with pTx.
