Abstract
A collimator is designed for use in rotational camera transaxial SPECT in which the camera head is inclined with respect to the axis of rotation. The principal ray of the collimator is offset so that the transaxial plane bisects the angle bounded by the radially outermost collimated rays (cone-beam case) or by the radially outermost fan strips (astigmatic and anamorphic cases.)
