  • Results are mean±SD.

  • Some data are missing because of the operating room table or X-ray system obstructing the measurement position. The radiation doses were measured per rotational acquisition in terms of the personal dose equivalent, Hp(10) (µSv), using standard clinical imaging protocols (described in table 1).
