Dynamic digital flat-panel (FD) imaging technology is characterised by a higher sensitivity and image quality compared to image intensifier (II) technology. In this study, an angiography system based on II and one based on FD were compared with respect to system performance and impact of patient dose in interventional cardiology. When entrance surface air kerma rates are measured, the FD system requires a reduced dose rate, of up to 40%. For coronary angiography (CA), fluoroscopy time (FT) and dose-area product (DAP) were 4.3 +/- 5.0 min and 31.2 +/- 30.2 Gy cm2 on the II system and 4.4 +/- 3.8 min and 33.4 +/- 19.2 Gy cm2 with the FD system. For percutaneous transluminal coronary angiography, FT and DAP were 11.4 +/- 10.7 min and 52.1 +/- 45.0 Gy cm2 on II and 10.7 +/- 8.7 min and 66.9 +/- 54.4 Gy cm2 on DF. Data comparison suggests that reduced entrance dose rates do not automatically imply a reduction of patient dose in clinical practice.
