<div dir="ltr">Hi all, I am trying to upsample an image using this example as base <a href="http://www.itk.org/Doxygen/html/Filtering_2ResampleVolumesToBeIsotropic_8cxx-example.html#_a5">http://www.itk.org/Doxygen/html/Filtering_2ResampleVolumesToBeIsotropic_8cxx-example.html#_a5</a><div>
I have MRI cine data with spacing like 1:1:8. I mounted all time frames into a 4D image and I would like to upsample on Z axis to get 1:1:1. I was wondering if I should better divide the 4D image into a vector of 3D images so the interpolator wouldn't mix different times frames or it doesn't matter. ( also because I am interested in performance). Is it ok to use the linear interpolator for MRI? Or I should use BSPline? If so, is it faster to work on 3D for the splines?? </div>
