ABSTRACT:
A method and device for producing nuclear images of an object under investigation which emits nuclear radiation, wherein the object is scanned along a scan axis by means of a radiation detector having a radiation detector field of view. The radiation detector field of view is masked by means of a mask field of view which partially exceeds the radiation detector field of view along the scan axis. The loss of sensitivity perpendicular to the scan axis in the parts of the mask field of view which exceed the radiation detector field of view is compensated by applying a weighting function proportional to the inverse of the incremental area along the scan axis bounded by the radiation detector field of view.
