fft#

mrinufft.extras.fft(image, dims, shape=None)[source]#

Compute n-dimensional FFT along the last dims axes.

Parameters:

  • image (NDArray)

  • dims (int) – Number of dimensions on which the fft is performed, starting from last. Required (no default): for an array with a leading non-spatial axis (e.g. coils), guessing the wrong dims silently transforms that axis too.

  • shape (tuple[int, ...], optional) – Output shape, by default same as output.

Returns:

Fourier Transform of image.

Return type:

NDArray
