Module Description

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

Use Cases

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