Bedside controller for assessment of vessels and associated devices systems and methods

A system for evaluating a vessel of a patient, comprising:

• a bedside controller comprising a processor and a touch-sensitive display, wherein the bedside controller is in communication with an external imaging device configured to obtain an image of a patient's anatomy, and a pressure-sensing guidewire or catheter sized and shaped for introduction into a vessel of the patient's anatomy and configured to obtain pressure data of the vessel, the bedside controller configured to:
• control the external imaging device to obtain the image based on user touch input on the touch-sensitive display;
• control the pressure-sensing guidewire or catheter to obtain the pressure data based on the user touch input on the touch-sensitive display;
• receive the image from the external imaging device;
• receive the pressure data from the pressure-sensing guidewire or catheter;
• co-register the image with the pressure data to generate a co-registered image;
• calculate a first pressure ratio based on the pressure data;
• output, to the touch-sensitive display, a screen display comprising:
• the co-registered image;
• and
• a numerical value of the first pressure ratio;
• and
• modify the screen display in response to the user touch input on the touch-sensitive display.
