Module Description

T1 mapping estimates effective tissue parameter maps (T1) from multi-spectral FLASH MRI scans with different flip angles.

The method and equations for Variable Flip Angle T1 Mapping are available here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3620726/pdf/nihms-423474.pdf

Use Cases

  • Take multi-spectral FLASH images with an arbitrary number of flip angles as input, and estimate the T1 values of the data for each voxel.
  • Read repetition time(TR), echo time(TE) and flip angles from the Dicom header directly.
  • Prostate, brain, head & neck, cervix, breast and etc.
