T1 mapping maps: build using VFA method

Build quantitative T1 map from two T1-weighted and BAFI correction map.

Description

Build quantitative T1 map from two T1-weighted and BAFI correction map (complex). Using the VFA method. The inverted map will not output the quantitative T1, but an inverted version which looks like a T1-weighted, so it can be suitable to be used as input to the Morphologist T1 pipeline. This is useful for high field MRI (7T) to replace T1 weighted images, which generally contain huge inhomogeneities and signal drifts. The quantitative T1 is (more or less) free of this bias.

Parameters

T1weighted_low_angle: Raw T1 MRI ( input )

T1weighted_high_angle: Raw T1 MRI ( input )

BAFI_amplitude_map: 4D Volume ( input )

BAFI_phase_map: 4D Volume ( input )

output_t1_map: Raw T1 MRI ( output )

invert: Boolean ( input )

BAFI_smoothing: Float ( input )
