- class mrinufft.operators.interfaces.torchkbnufft.TorchKbNUFFTcpu(*args, **kwargs)[source]#
Bases:
MRITorchKbNufft
MRI Transform Operator using Torch NUFFT for CPU.
This class provides a Non-Uniform Fast Fourier Transform (NUFFT) operator specifically optimized for CPU using the torchkbnufft library. It inherits from the MRITorchKbNufft class and sets the use_gpu parameter to False.
