The imaging system obtains a first set of images at the first frame rate based on the first control signal. At least one parameter of a catheter procedure performed by the catheter procedure system is determined and a second control signal is generated based on the at least one parameter of the catheter procedure. The second control signal indicates a second frame rate. The second control signal is provides to the imaging system to adjust the first frame rate to the second frame rate. The imaging system obtains a second set of images at the second frame rate and displays the second set of images on a display. ## Claims ### Claim 1 A method for controlling x-ray frame rate of an imaging system for a catheter procedure system, the method comprising: generating a first control signal that indicates a first frame rate;
