Betreff: [mitk-users] Bugfix Patch for QmitkRigidRegistration Functionality
Manual Interactive Translations
Dear MITK developers,
I had a problem using the interactive manual translation of the
RigidRegistration functionality. In my case I tried to manually align two
datasets (one CT and one ultrasound dataset). To initially align the two
datasets I had to position the (much smaller) ultrasound volume at a certain
location in space which is different from 0,0,0 in x,y and z direction. This
was done by modifying the header file of the dataset.
When I tried to use the manual sliders to correct my initial alignment a bit,
an error occurred. The ultrasound volume was pushed back to 0,0,0 and then
translated just by the amount given by the slider positions. Looking at the
code I found out that it is not correct to subtract the old volume position
from the translation vector given by the sliders. This approach only works for
volumes at 0,0,0.
Please have a look at my patch, where I store the old slider values and
translate the volume by the difference between these stored values and the
current slider values.
Best wishes,
Matthias
