Controller user interface for a catheter lab intravascular ultrasound system

A method of performing measurements on image data with a processing unit and a bedside controller sized and shaped for both handheld use and mounting on a rail adjacent a patient table, comprising:

• receiving a first user actuation in a first region of the bedside controller to control acquisition of the image data, wherein the bedside controller includes a plurality of actuation control regions grouped based on functionality, wherein the regions include the first region having a set of imaging action controls for controlling patient image data acquisition, a second region having navigation controls, wherein the navigation controls include a touch-sensitive touchpad sensor array configured to sense a touch of a user to allow the user to control positioning and actuation of a cursor on a display in communication with the bedside controller, the touchpad sensor array being further configured to accept measurement inputs to make measurements on acquired patient image data corresponding to a selected measurement option of a plurality of selectable measurement options, and a third region having controls for reviewing the acquired image data, the third region including a measure button that provides user access to the plurality of selectable measurement options;
• receiving a second user actuation in the third region of the bedside controller, the second user actuation being actuation of the measure button to select a measurement option out of a plurality of measurement options to which the measurement button provides access;
• receiving a third user actuation in the second region of the bedside controller, the third user actuation being a user measurement input on the touchpad sensor array corresponding, to the selected measurement option;
• and
• performing measurements on the acquired image data using a processing unit in communication with and separately spaced from the bedside controller based on the user measurement input and the selected measurement option of the plurality of measurement options.
