DSA programmed settings for the image-receptor (detector) entrance air kerma rate for a typical patient examination with the largest FOV on both platforms^a

System	DRT	Acquisition Protocol	kV	Filtration	Focal Spot (mm)	Programmed RAKR (μGy/frame)
FD 20/20	No	Standard	80	0.1 mm Cu +1 mm Al	Large (AP/LAT: 0.7 mm)	4.0
FD 20/10	Before	Standard	80	0.1 mm Cu +1 mm Al	Large (AP: 0.7 mm; LAT: 0.8 mm)	4.0
	After	Quarter	75	0.1 mm Cu +1 mm Al	Small (AP: 0.4 mm; LAT: 0.5 mm)	0.7
		Half	78	No added filtration	Small (AP: 0.4 mm; LAT: 0.5 mm)	1.0
		Full	80	0.1 mm Cu +1 mm Al	Large (AP: 0.7 mm; LAT: 0.8 mm)	4.0

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

^aThe 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.
