  • Note:—AP indicates anteroposterior; DRT, dose-reduction technology.

  • a The dose-reduction platform was equipped with 3 acquisition protocols in which the “full-dose” protocol reverts to the reference platform hardware and software settings (“standard” dose protocol). The programmed settings are identical for both planes in each system and for each acquisition protocol.
