Wunderle KA, Rakowski JT, Dong FF. Approaches To Interventional Fluoroscopic Dose Curves. J Appl Clin Med Phys. 2016 Jan 8;17(1):342-352.

This study evaluated and compared approaches to technique factor modulation and air kerma rates in response to simulated patient thickness variations for four state-of-the-art and one previous-generation interventional fluoroscopes. The data obtained indicated vendor- and model-specic variations in the approach to technique factor modulation and reference plane air kerma rates across a range of tissue thicknesses. However, in the imaging protocol evaluated, all of the state-of-the-art systems had relatively low air kerma rates in the fluoroscopic low-dose imaging mode as compared to the previous-generation unit. Some vendors have also enhanced the radiation output capabilities of their fluoroscopes which, under specic conditions, may be beneficial; however, these increased output capabilities also have the potential to lead to unnecessarily high dose rates.
