Purpose: The main goal is to demonstrate the effects of varying imaging equipment parameters have upon patient radiation dose in modern cardiac catheterization x‐ray systems. The parameters examined include: pulse rate, Field‐of‐View (FoV), patient thickness, fluoroscopy versus record mode, SID settings and ABC programs. Method and Materials: A Siemens flat panel Axion Artis FC cardiac unit was used. The patient was simulated by sheets of acrylic varying in thickness from 10 cm to 30 cm. The exposure rate was measured at the entrance surface of the acrylic with an ionization chamber. Results: The entrance exposure rate varied with the (FoV) N where −2
