The point spread function in the space domain for a certain collimator and source position can be calculated via a discrete fast Fourier transform. Beside the complete theoretical definition of the response of multihole collimators, this theory allows the collinators of accurate models of the geometrical response for SPECT reconstruction and it is suitable for designing new collimators.
