Abstract :
A method to compute the system function of gamma-ray multichannel collimators having a point spread which is periodic in the angle when expressed in polar coordinates is described. This is the case when the cross section of the channel distribution is hexagonal, for example. The computation is done in terms of sample of the responses to a finite number of lines.
