This could also be an issue for other operators.
It should be possible to create them even after moving data to cuda.
Currently, you would have to move to CPU, create, move to GPU again..

Could be solved with kx_idx = repeat(torch.arange(...., device=ktraj_tensor.device).... and also in ky and kz_idx in CartesianSamplingOp
