Abstract

An imaging system includes a stationary frame (104) and a pivotable frame (106) that is pivotably attached to the stationary frame (104) and configured to pivot about a transverse axis (108). A rotating frame (110) is rotatably supported by the pivotable portion (106) and configured to rotate about a longitudinal axis (114) around an examination region (112) and a rotating frame balancer (118) selectively introduces a rotating frame mass imbalance. A radiation source (116) is affixed to the rotating frame (110) and emits radiation from a focal spot, wherein the radiation traverses the examination region (112). A detector array (128) detects the radiation that traverses the examination region (112) and generates a signal indicative thereof.
