Controller user interface for a catheter lab intravascular ultrasound system

摘要

A touchpad controller for a componentized intravascular ultrasound system is disclosed for acquisition and display of intravascular information in a catheter lab environment. The system includes a patient interface module (PIM) adapted to hold a catheter having an imaging probe located near a distal end, a control panel, a monitor for displaying images and patient data, and a processing unit. The touchpad controller facilitates use beneath a sterile drape and sensitivity to gloved touch. Furthermore, the touchpad controller is sized for handheld use during an imaging session. A rail mount facilitates easy attachment of the touchpad controller alongside a patient table.

主权项

1. A method of performing measurements on patient image data, comprising:
selecting a measurement option from a plurality of selectable measurement options of a bedside controller, the bedside controller including a housing sized and shaped for both handheld use and mounting on a rail adjacent a patient table, wherein the bedside controller further includes a plurality of actuation controls grouped into regions based on functionality, wherein the regions include a first region including a set of imaging action controls for controlling patient image data acquisition, a second region including 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 the selected measurement option of the plurality of selectable measurement options, and a third region including controls for reviewing the acquired patient image data, the third region including a measure button that provides user access to the plurality of selectable measurement options; executing a measurement on the acquired patient image data based on the selected measurement option of the plurality of selectable measurement options when the measurement input corresponding to the selected measurement option is received on the touchpad sensor array; and displaying the acquired patient image data and the measurement executed based on the selected measurement option of the plurality of selectable measurement options on a display in communication with the bedside controller.
