This study aimed to quantify the dose and quality of the preprogrammed imaging modes on two cardiac angiography devices (Philips Allura FD10 Clarity and Allura FD10) using a task-specific in-house phantom, and to discuss the appropriateness of the pre-programmed settings. A Figure of Merit (FOM), defined as the squared Signal Difference to Noise Ratio (SDNR) divided by Entrance Surface Air Kerma (ESAK), was calculated for phantom inserts with different sizes and concentrations of iodine, as well as tin foils. For the Allura FD10 Clarity device, the low dose fluoroscopic mode was found to be very dose efficient, while the available ciné modes should only be used for cases with high demand for contrast and temporal resolutions. For both devices, the basic beam spectrum of the low dose fluoroscopic mode should be explored for use on other imaging modes. Ciné modes for the Allura FD10 device differ only by their spatial resolution characteristics and have almost identical dose per frame. This study also found that tin may not be a suitable replacement for iodine for research purposes due to mismatching SDNR. The number of recommendations formulated for these two devices suggests that comparative dose and image quality tests of all routinely used imaging modes should be an obligatory part of the physicists’ acceptance testing.
