ABSTRACT:
A method of controlling quality in a nuclear medicine imaging system includes providing an extendable radioactive source in a frame of the nuclear medicine imaging system, providing a detector having a field of view above the source, extending the radioactive source, moving the detector from a first position to a second position, acquiring a plurality of images of the radioactive source with the detector during the movement, summing the plurality of images to form a flood image of the source, and assessing a quality of the detector image using the flood image. An extendable shield having a plurality of windows disposed along a length of the shield may be disposed about a line source so that the windows form an array of point sources when the source and the shield are extended.
