kspace_as_real#

mrinufft.operators.autodiff.kspace_as_real(y)[source]#

View k-space data as real-valued tensor.

Converts a complex k-space tensor of shape (B, C, K) to a real-valued tensor of shape (B, C, K, 2) where the last dimension holds the real and imaginary parts.

Parameters:

y (torch.Tensor) – Complex k-space tensor of shape (B, C, K).

Returns:

Real-valued tensor of shape (B, C, K, 2).

Return type:

torch.Tensor
