Table 4.

Entrance dose rate during fluoroscopy and dose per frame during cine for different source‐image detector distances. ^a

Source—image Detector Distance (cm)	Fluoroscopy Dose Rate $(mGy/min)$	Cine Dose per Frame $(\mu \hspace{0.17em}Gy/fr)$
100	$13.04\pm 0.22$	$214.67\pm 2.52$
110	$16.09\pm 0.24$	$266.00\pm 2.00$
120	$19.69\pm 0.80$	$318.00\pm 3.00$

^aEntrance dose rate and dose per frame were measured at the patient entrance reference point in the anterior‐posterior projection (in the low fluoroscopy mode with 25 cm field of view and $15\hspace{0.17em}\text{fr}/\mathrm{s}$ for both fluoroscopy and cine)
