A nuclear medicine imaging system includes a bed having a direction of translation, a detector disposed rotationally about an axis of rotation substantially parallel to the direction of translation, and a radioactive line source disposed rotationally about the bed substantially opposite the detector at a first predetermined non-zero angle to the axis of rotation and a second predetermined non-zero angle to a plane of rotation of the detector. The bed may be translated along the along the direction of translation while the detector is rotated about the axis of rotation.
