B1MapCalc
B1MapCalc[data,TR,alpha]
calculates the B1 map from a dual TR {tr1, tr2} acquisition (AFI) using magnitude data with reference angle alpha. data has dimensions {z, {tr1,tr2}, x, y}.
B1MapCalc[dataTr1,dataTr2,TR,alpha]
where dataTr1 and and dataTr2 can have any dimensions. The Output can be "Map", "MagPhase", or "Complex"}
is based on DOI: 10.1002/mrm.21120.
Details
- The following options can be given:
-
B1Output "Map" B1Output is an option for B1MapCalc. Values can be "Map", "MagPhase", or "Complex". B1Masking True B1Masking is an option for B1MapCalc. If True then values where S2 is larger than S1 are masked. B1FilterData True B1FilterData is an option for B1MapCalc. If True HammingFilterData is applied to the data before B1 calculation. ReferenceB1 None ReferenceB1 is an option for B1MapCalc. Default value is None. Can be given a numeric value in uT.
