[Rtk-users] reading Elekta database projections

[Simon Rit]

Hi,
To read in the projections, you should create an array with the filenames
(name filenames below) and then
ImageType = itk.Image[itk.F, 3]
proj = rtk.ProjectionsReader[ImageType].New()
proj.SetFileNames(filenames)
proj.Update()
nparray = itk.GetArrayFromImage(proj.GetOutput())
This should work.
