Hi Nibabel maintainers, I did some research on how to use Kvikio + Nibabel to load .nii images into GPU directly, it helps accelerate the loading time especially on large (100MB+) images.
A solution is confirmed work:

  1. using kvikio to load .nii file as bytes from disk into gpu
  2. using nibabel to load headers of the file from disk into cpu
  3. parse bytes according to headers.

Welcome to discuss it, thanks in advance!
