In plain language
In phantom bench tests of a standard cine protocol, patient radiation dose differed up to about fourfold between four cath lab X-ray systems. Staff dose was not measured, though lower patient dose generally means less scatter to the fluoroscopy team.

What it found
The Philips Allura Clarity system produced the lowest phantom radiation dose.
Key figures: average film dose 4.2±0.1 cGray; air kerma (AK) 0.310±0.002 Gray; dose-area product (DAP) 23.72±0.84 Gray*cm2
The GE Innova IGS and Siemens Artis one systems produced the highest doses, roughly three to four times the DAP of the lowest system.
Key figures: Innova IGS DAP 92.28±14.73 Gray*cm2; Artis one DAP 75.93±9.11 Gray*cm2
Differences between systems were statistically significant across all dose measures.
Key figures: P=0.011 average film dose; P=0.019 maximum film dose; P=0.033 AK; P=0.008 DAP
The older Philips Integris Allura FD20 produced intermediate dose.
Key figures: average film dose 4.4±1.1 cGray; DAP 45.18±21.90 Gray*cm2
Limits to keep in mind
Phantom bench testing with only 3 to 7 experiments per system and a single cine protocol; measures patient-entrance dose rather than staff dose, and system settings or configurations may not reflect clinical use.
