Abstract

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.

Claims

1-15. -15. (canceled)

16. A method of performing measurements on patient image data, comprising:

providing a multi-region control panel including;

a housing having a height between about 4 inches and about 10 inches, a width between about 6 inches and about 10 inches, and a thickness less than about 2 inches such that the control panel is sized and shaped for both handheld use and mounting on a rail adjacent a patient table;

wherein the control panel includes a plurality of actuation controls grouped into regions based on functionality, wherein the regions include a first region including a set of IVUS action controls for controlling patient image data acquisition, a second region including pointer navigation controls, wherein the pointer navigation controls comprise 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 user interface display associated with a processing unit the control panel is in communication with, the processing unit being housed separately from the control panel such that the control panel is independently positionable with respect to the processing unit, 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 a plurality of selectable measurement options;

selecting a measurement option from the plurality of selectable measurement options;

making measurement inputs through the touchpad sensor array such that measurements are made on the acquired patient image data based on the selected measurement option of the plurality of selectable measurement options.

17. The method of claim 16, wherein providing user access through the measure button to a plurality of selectable measurement options includes providing user access to at least one of a diameter measurement option, a length measurement option, and a border measurement option.

18. The method of claim 16, wherein the provided multi-region control panel is sealed and insulated to facilitate use alongside a patient on the patient table.

19. The method of claim 16, wherein the second region of the provided multi-region control panel includes a bookmark button operable to select a specific image frame to be measured out of the acquired patient image data.

20. The method of claim 16, wherein the first region of the provided multi-region control panel includes a record button operable to commence recordation of a sequence of patient image frames.

21. The method of claim 16, further including proving a mounting bracket configured to mount the provided multi-region control panel to a rail of the patient table.

22. A method of performing measurements on intravascular ultrasound (IVUS) image data with a processing unit and a multi-region medical imaging control panel sized and shaped for both handheld use and mounting on a rail adjacent a patient table, comprising:

receiving a first user actuation of a set of action controls in a workflow region of the control panel to control acquisition of the IVUS image data;

receiving a second user actuation of a measure button in the workflow region to select a measurement option out of a plurality of measurement options to which the measurement button provides access;

sensing, through a touch-sensitive touchpad controller in a navigation region of the control panel, a user measurement touch input; and

performing measurements on the acquired IVUS image data using the processing unit based on the user measurement touch input and the selected measurement option of the plurality of measurement options.

23. The method of claim 22, wherein the plurality of selectable measurement options includes at least one of a diameter measurement option, a length measurement option, and a border measurement option.

24. The method of claim 22, further including receiving the user measurement touch inputs while the control panel is mounted to a rail on the patient table.

25. The method of claim 22, wherein receiving the first user actuation includes receiving an actuation of a record button to commence recordation of a sequence of IVUS image frames being acquired by an IVUS catheter communicatively coupled to the processing unit.

26. The method of claim 25, wherein receiving the first user actuation includes receiving an actuation of a bookmark button to select a specific IVUS image frame out of the recorded sequence of IVUS image frames to be measured.

27. A method of performing measurements on patient image data with a medical imaging control panel, comprising:

receiving a first user actuation of a workflow button on the control panel to select the patient image data, the control panel being positioned adjacent to a patient table;

receiving a second user actuation of a measure button on the control panel to select a measurement option out of a plurality of measurement options to which the measurement button provides access;

receiving user measurement inputs through a controller on the control panel to perform measurements on the patient image data based on the selected measurement option of the plurality of measurement options.

28. The method of claim 27, wherein the plurality of selectable measurement options includes at least one of a diameter measurement option, a length measurement option, and a border measurement option.

29. The method of claim 27, wherein receiving user measurement inputs includes sensing user touches with a touch-sensitive touchpad controller.

30. The method of claim 29, wherein sensing user touches includes sensing user touches with the touchpad controller through a sterile drape.

31. The method of claim 29, wherein sensing user touches includes sensing the gloved touch of a user.

32. The method of claim 27, further including providing tactile feedback to a user with raised edges outlining the measurement button.

33. The method of claim 27, further including receiving, before receiving the first user actuation, a third user actuation of a record button on the control panel to commence recordation of a sequence of intravascular ultrasound (IVUS) image frames.

34. The method of claim 27, wherein the patient image data is a frame of intravascular ultrasound (IVUS) image data.

35. The method of claim 27, further including receiving the user measurement touch input while the control panel is mounted to a rail on the patient table.
