Abstract
A medical imaging apparatus includes a stationary gantry and a generally spool-shaped rotating gantry (304), which rotates about an examination region about a longitudinal axis. The rotating gantry includes a first flange (320), a second flange (322), and a plurality of elongate structural elements (402) that are disposed between and couple' the first and second flanges. The first flange (320) is rotatably coupled to the stationary gantry, and the second flange (322) extends radially in a plane perpendicular to the longitudinal axis, thereby providing radial stiffness for the rotating gantry. A radiation source is affixed to the rotating gantry between the first and second flanges, and a detector array is affixed to the rotating gantry between the first and second flanges, opposite the examination region from the radiation source.
