Abstract:
A patient support comprising:a base; a first supporting arm pivotally mounted at a first end to the base, the first supporting arm comprising linkages pivotally connected together at four points which define a first parallelogram, a first side of which is fixed relatively to the base in a predetermined orientation, a second opposite side of which, at the second end of the first supporting arm, thereby being constrained to have the same predetermined orientation; a second supporting arm pivotally mounted at a first end to the second end of the first supporting arm, and comprising linkages pivotally connected together at four points which define a second parallelogram, a first side of which, at the first end of the second supporting arm, is fixed to and has the same orientation as the second side of the first parallelogram, a second opposite side of which, at a second end of the second supporting arm, thereby being constrained to have the same orientation; a support member connected to the second end of the second arm; and a patient support table coupled to the support member, means being provided for controlling the pivotal connections between the base and the first supporting arm and between the first supporting arm and the second supporting arm.
