Abstract
An alignment system for use in connection with a patient handling system and a nuclear medicine gantry is provided. The alignment system includes a nuclear camera alignment fixture mountable to the nuclear detector. The nuclear camera alignment fixture includes a pair of lasers mounted in a known position relative to a center of the nuclear detector and oriented substantially toward the nuclear medicine gantry. The nuclear camera alignment fixture further includes a pair of laser targets provided on the nuclear medicine gantry. Each laser target has a fixed location with respect to an axis of rotation of the nuclear medicine gantry. The nuclear detector is moved relative to the nuclear medicine gantry until a laser beam from each laser hits a respective laser target. The alignment system is also capable of aligning the patient handling system with respect to the axis of rotation of the nuclear medicine gantry.
