1. A SPECT scanner for making images of an object using gamma radiation emitted by the object, comprising:
an object space with a longitudinal direction;
an object carrier configured for bringing an object into the object space in said longitudinal direction and for positioning the object in the object space;
a collimator that extends in a circumferential direction thereof at least partially around the object space, wherein the collimator comprises a set of multiple pinholes each of the set of multiple pinholes comprising a field of view with a main pass-through direction for gamma radiation emitted by the object; and
a detection device with at least one detector configured for detecting gamma radiation that is allowed to pass through from the object space by one or more of the pinholes, wherein the collimator is provided between the object space and the at least one detector,
wherein the collimator is provided with at least one rotatable pinhole body with at least one pinhole therein, the pinhole body being rotatably arranged in the collimator around at least one corresponding axis of rotation.
