Claim 6:
7. The SPECT scanner according to claim 1, wherein the collimator is provided with at least one rotatable pinhole body with at least one pinhole therein, wherein the at least one pinhole extends from a first opening on a first side of the pinhole body to a second opening on a second side of the pinhole body located opposite the first side,
wherein the at least one pinhole has a smallest cross-sectional part that defines the smallest cross-section for gamma radiation of the pinhole and is located at a distance from the first opening and the second opening of the pinhole, and
wherein the smallest cross-sectional part, seen in a direction between the first opening and the second opening of the pinhole, is located at a distance from the axis of rotation of the pinhole body, such that during use a distance between the smallest cross-sectional part of the pinhole and an object positioned by the object carrier is variable by selectively rotating the pinhole body with the first side thereof or the second side thereof toward the object space.
