The invention comprises a virtual window system that creates a visual coherency between the image of the patient and his or her anatomy and the patient by aligning the image of the patient anatomy on the display to the patient and presenting the image to the user that feels as if the user is looking directly into the patient through the display. The invention is designed to also display medical devices, such as a minimally invasive tool. The system substantially unifies the coordinate systems of the patient, the medical device, the display, and the physician's hands. The invention creates a visual coherency between the motion of the medical device in the image and the motion of the physician's hands manipulating the device. This invention also creates a visual coherency between the motion of the image in the display and of that display.

A robotic surgical system configured for the articulation of a catheter comprises an input device, a control computer, and an instrument driver having at least one motor for displacing the pull-wire of a steerable catheter wherein the control computer is configured to determine the desired motor torque or tension of the pull-wire of a catheter based on user manipulation of the input device. The control computer is configured to output the desired motor torque or tension of the pull-wire to the instrument driver, whereby at least one motor of the instrument driver implements the desired motor torque to cause the desired pull-wire tension to articulate the distal tip of the catheter. The present embodiment further contemplates a robotic surgical method for the articulation of a steerable catheter wherein an input device is manipulated to communicate a desired catheter position to a control computer and motor torque commands are outputted to an instrument driver. The robotic system may further comprise a torque sensor. The robotic system may also incorporate closed loop feedback in which data from the torque measuring device is used to ensure that the torque in the motor or tension in the pull-wire closely matches the motor torque command from the control computer.
