So sorry, everyone, I sent it to the wrong place.

Dear all,

I would like to ask some questions about the 4 methods used for IVIM maps calculation in MITK diffusion software.

1.May I ask what is the fitting algorithm for method 1 (jointly fit D, f and D*), Levenberg–Marquardt or Trust-Region algorithm or other algorithm?
2. For method 3, did it use Segmented-Unconstrained algorithm or Segmented-Constrained algorithm (D is computed by assuming that the intercept of the diffusion-related signal is equal to S0)?
3. Any reference publications for method 4?

If it is possible for you to send the specific reference publications for these 4 methods, it would be great! Thank you in advance!

Best,
Yan

Hi Raphael,

yes, this is a job for your mapper. For example, see mitkBoundingShapeVtkMapper3D.cpp (GenerateDataForRenderer()). Here, local coords are used and vtkTransforms are then used to apply the geometry. You can also work with global coords without transforms if that works better for your mapper.

Best,
Stefan

Betreff: [Extern] - [mitk-users] Custom MITK data and renderer

Dear All,

I’m trying to implement my own custom data type (based on BaseData) with its own custom mapper (based on VtkMapper).

It works fine and shows the visualisation correctly.

However, I cannot see where the geometry enters the picture. If I add an offset or a rotation to the data, the visualisation does not follow. It this a job for my mapper? I do not understand by looking at the existing codebase where the magic happens for existing MITK types and mappers.

Thanks for your help,

Raphael
