1. A method of performing measurements on medical images with a bedside controller, the method comprising:
receiving, through a touch-sensitive display on the bedside controller, a user measurement input on an intravascular image displayed on the display, the intravascular image obtained in real time by an intravascular imaging device within a vessel of a patient, the intravascular imaging device including at least one of an ultrasound transducer and an optical coherence tomography (OCT) component, wherein the intravascular imaging device is controlled by the bedside controller, and wherein the user measurement input includes a start point on the intravascular image defined by a point of initial contact with the touch-sensitive display and an end point on the intravascular image defined by a point of last contact with the touch-sensitive display; selecting a measurement mode from a group of measurement modes including a diameter measurement mode, an area-point measurement mode, and an area-draw measurement mode based on the user measurement input without requiring a user to select the measurement mode prior to making the user measurement input on the touch-sensitive display, wherein selecting the measurement mode includes:
determining if a distance between the start point and the end point is less than a threshold distance;selecting an area-point measurement if the distance between the start point and the end point is less than the threshold distance;determining, when the distance between the start point and the end point is greater than a threshold distance, if any intervening points along the user measurement input between the start point and the end point fall outside of a boundary threshold;selecting the diameter measurement mode if none of the intervening points fall outside of the boundary threshold; andselecting the area-draw measurement mode if at least one intervening point falls outside of the boundary threshold; calculating a measurement value associated with the user measurement input based on the selected measurement mode; and displaying the calculated measurement value on the touch-sensitive display.
