<div style="width: 27%; float: left; padding-right: 3%;">
<h3>Objective</h3>
* Estimate effective T1 from multi-spectral FLASH MRI scans with different flip angles
</div>
<div style="width: 27%; float: left; padding-right: 3%;">
<h3>Approach, Plan</h3>
* Create a Slicer module for T1 mapping for multiple flip angles using Python script
* Run Python script and [https://surfer.nmr.mgh.harvard.edu/fswiki/mri_ms_fitparms  Freesurfer code] on [https://dblab.duhs.duke.edu/modules/QIBAcontent/index.php?id=1  QIBA T1 phantom]
* Test the Slicer module on MGH Brain Tumor MR Data with multiple flip angles
</div>
<div style="width: 27%; float: left; padding-right: 3%;">
<h3>Progress</h3>
* Comparing the results using Python with Freesurfer and ground truth of T1
* T1 mapping results on QIBA data using Slicer+Python are almost identical to the results using Freesurfer and comparable with the ground truth
