Abstract
A mobile radiography apparatus has a portable transport frame. A sectioned vertical column mounted on the frame defines a vertical axis and has a base section having a fixed vertical position relative to the vertical axis and at least one movable section that is translatable to a variable vertical position. A boom apparatus supports an x-ray source and extends outward from the movable section and has an adjustable height relative to the vertical axis. A counterweight is operatively coupled to the boom apparatus to support displacement of the boom apparatus to any of a plurality of vertical positions along the movable section, wherein the counterweight, in cooperation with boom apparatus movement, travels along a shaft that extends within the movable section, wherein, at one or more of the height positions of the boom apparatus, a portion of the counterweight extends upward above the shaft of the sectioned vertical column.
