Abstract:
1. A mobile radiography apparatus comprising: a wheeled transport frame; a sectioned vertical column mounted on the frame and defining a vertical axis and comprising, a boom apparatus to support an x-ray source; a boom transport mechanism coupled to the first movable section or the middle section, wherein the boom transport mechanism is actuable to provide vertical movement along at least a portion of the first movable section or the middle section, wherein the boom apparatus is coupled to the boom transport mechanism for positioning of the x-ray source along the vertical axis and extends outward with respect to the sectioned vertical column for positioning of the x-ray source in a direction that is orthogonal to the vertical axis, and where a mechanical advantage of the pulley configuration in the sectioned vertical column balance a weight of movable components including the first movable section, the middle section, the boom apparatus, and the boom transport mechanism to allow a substantially uniform force to adjust a height of the movable components within a height range of the movable components relative to the vertical axis.
