Hi,<br> <br> I am executing the MultiResMIRegistration software with the following parameter file: <br> <br> Axialsaggre711-05082006.img<br> interpolatedPerfusion711-05082006.img<br> 0 1 2<br> 0 0 0<br> 5<br> 4 4 1<br> 8 8 1<br> 2500 2500 2500 2500 2500<br> 1e-6 1e-6 5e-6 5e-6 5e-7<br> 320<br> Reg_perfusion711-05082006.img<br> <br> I ran the same script a few times and observed that in each run the values of the Final Parameters and the Overall transform matrix in the output were quite different. The Overall Tranform set seems reasonably close though. For example: <br> <br> <span style="font-weight: bold;">Run 1: </span><br> <br> Final parameters: [-0.00351486, 0.000741038, 0.000685894, 0.999993, 0.533468, -2.82873, 1.43219]<br> Overall transform matrix: <br> 0.999998 -0.00137699 0.00147724<br> 0.00136657 0.999974 0.00703069<br> -0.00148689 -0.00702866 0.999974<br> <br> Overall transform offset: <br> [40.5209, -3.84145, -95.5383]<br>
===========================================================<br> <span style="font-weight: bold;">Run 2: </span><br> <br> Final parameters: [-0.00274307, 0.00195265, -0.000717365, 0.999994, -1.14514, -1.45365, 2.23317]<br> Overall transform matrix: <br> 0.999991 0.00142401 0.00390921<br> -0.00144543 0.999984 0.0054833<br> -0.00390134 -0.0054889 0.999977<br> <br> Overall transform offset: <br> [38.1756, -2.02425, -94.7227]<br> <br> What is the reason for this inconsitency? How can this be solved?<br> <br> Thanks a lot in advance. <br> <br> Sincerely,<br> Dhiral Phadke.<br> <p>
