fft

mrinufft.extras.cartesian.fft(image, dims=3, shape=None)

Compute n-dimensional FFT along the last dims axes.

Parameters:

• image (NDArray)

• dims (int, default 3) – Number of dimensions on which the fft is performed, starting from last.

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

Returns:

Fourier Transform of image.

Return type:

NDArray
