make_b0map# mrinufft.extras.field_map.make_b0map(shape, b0range=(-300, 300), mask=None)[source]# Make radial B0 map. Parameters: shape (tuple[int]) – Matrix size. b0range (tuple[float], optional) – Frequency shift range in [Hz]. The default is (-300, 300). mask (np.ndarray) – Spatial support of the object. If not provided, build a radial mask with radius radius=0.3*shape Returns: np.ndarray – B0 map in Hz, values included in b0range, and shape shape np.ndarray – Spatial support binary mask
