Abstract: An imaging system (100) includes a rotating frame (106), a second frame (102, 104), and a support (108) that rotatably couples the rotating frame (106) to the second frame (102, 104). One of the rotating frame (106) or the second frame (102, 104) is compliantly coupled to the support (108) and the other of the rotating frame (106) or the second frame (102, 104) is rigidly coupled to the support (108). An imaging system includes a rotating frame (106), a tilt frame (104), and a stationary frame (102). A frame stiffener (110) provides structural support for the rotating and tilt frames (106, 104) along transverse axes. An imaging system (100) includes a rotating frame (106) and a second frame (102, 104) that rotatably supports the rotating frame (106). The rotating frame (106) is coupled to the second frame (102, 104) through a contactless bearing and controlled by a contactless mechanism. A braking component (112) selectively applies a brake to the rotating frame (106).

Abstract: A medical imaging system includes a stationary gantry and a rotating gantry that rotates around an examination region about a z-axis. An air bearing rotatably couples the rotating gantry to the stationary gantry. A radiation source is affixed to the rotating gantry and rotates with the rotating gantry and emits radiation that traverses the examination region. A detector array is affixed to the rotating gantry on an opposite side of the examination region with respect to the radiation source and detects radiation traversing the examination region. A dynamic z-axis imbalance determination system determines an imbalance of the rotating gantry in the z-axis direction directly from the air bearing, and the determined imbalance is used to position a balance mass affixed to the rotating gantry in the z-axis direction, thereby balancing the rotating gantry along the z-axis.
