Fix the 3d+t <> diffusion-weighted image conversions
Closed, ResolvedPublic

Description

With the API changes in the diffusion-weighted images, the filter containing the conversion between 3d+t (needed by registration) and itkVectorImage layout (the format of the diffusion-weighted image) was removed.

As a consequence of this change, the HeadMotionCorrectionfilter is not producing correct result (currently the 3d+t image is passed into the output dw-image which compiles, but is wrong)

Proposed solution:

  • provide an ImageToImageFilter accepting 3d+t image and the needed header information as input and producing a dw-image ( mitk::Image with DW Properties) as output
