ABSTRACT:
A patient bed is provided having an elevation mechanism resting on a platform and a collimator assembly, where the weight of the collimator assembly is selectively supported by one of the combination of the elevation mechanism and the platform when there is no patient laying on a mattress of the patient bed, and the platform alone when there is a patient laying on the mattress of the patient bed. The patient bed further includes first and second docking assemblies respectively mounted to a bed frame and the platform for docking the collimator assembly. The docking assemblies include self-aligning guide pins for maintaining a horizontal position of the collimator assembly and its collimators therein during docking and post-docking.
