A robotic catheter procedure system for performing a procedure on a patient is provided. The robotic catheter procedure system includes a bedside system and a remote workstation. The bedside system includes a percutaneous device and an actuating mechanism configured to engage and to impart movement to the percutaneous device. The remote workstation includes a user interface configured to receive a user input and a display device configured to display an image of a portion of the patient. The image includes a magnification level. The workstation also includes a control system operatively coupled to the user interface. The control system is configured to generate a control signal. The actuating mechanism causes movement of the percutaneous device in response to the control signal, and the control signal is based upon the user input and the magnification level.
