sigpy.mri.linop.ConvImage

sigpy.mri.linop.ConvImage(mps_ker_shape, img_ker, coord=None, weights=None, grd_shape=None)

Convolution linear operator with image kernel in k-space.

Parameters:

• mps_ker_shape (tuple of ints) – sensitivity maps kernel shape.
• img_ker (array) – image kernel.
• coord (array) – coordinates.
• grd_shape (None or list) – Shape of grid.
