FIELD: physics.SUBSTANCE: invention relates to an imaging system and method. The system includes a stationary frame and a pivoting frame which is pivotably attached to the stationary frame and configured to pivot about a transverse axis. A rotating frame is rotatably supported by the pivoting portion and configured to rotate about a longitudinal axis and around an examination region, and a rotating frame balancer selectively introduces a rotating frame mass imbalance. A radiation source is attached to the rotating frame and emits radiation from a focal spot, wherein the radiation traverses the examination region. A detector array detects the radiation which traverses the examination region and generates a signal indicative thereof. A reconstruction unit reconstructs signals generated by the detector array and generates image data.EFFECT: complete sampling of a volume of interest without artefacts.15 cl, 11 dwg |
