Abstract
The present invention relates to an apparatus for nuclear medicine imaging in which the imaging platform is attached directly to the detectors for nuclear imaging to allow for minimal constant distance between the detector(s) and the object to be imaged. As the detector moves around the object to be imaged to capture different angular views of the object, the imaging platform is rotated in a compensatory manner to maintain a its long axis perpendicular to gravity during movement of the detector. An advantage of this configuration over prior systems is the ability to obtain multiple angular projections while the distance between the detector and the object being imaged is maintained at a minimum, but the danger of detector-object collision is minimized and the necessity for orbital path calibration to preserve precision of detector movement and distance is eliminated.
