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. A multi-region control panel, for an IVUS system, through which a user controls acquisition and display of IVUS image information, the control panel including a physical interface divided into regions/sectors associated with particular workflow functionality, the regions/sectors comprising:

a first region including a set of IVUS action controls for controlling patient image data acquisition; and

a second region including pointer navigation controls, wherein the pointer navigation controls comprise a touch-sensitive touchpad sensor array.

2. The multi-region control panel of claim 1 wherein the touchpad sensor array is operable when covered by a sterile drape.

3. The multi-region control panel of claim 1 wherein the touchpad sensor array is pressure-sensitive.

4. The multi-region control panel of claim 1 wherein the touchpad sensor array supports gloved touch.

5. The multi-region control panel of claim 1 wherein the pointer navigation controls support multi-button mouse functionality.

6. The multi-region control panel of claim 1 further comprising a rapid review control for viewing a pre-selected image frame sequence.

7. The multi-region control panel of claim 1 further comprising a back and a forward button set facilitating stepping through image frames a single frame at a time.

8. The multi-region control panel of claim 1 wherein the back and forward button set facilitates scrolling rapidly through multiple image frames by holding down either one of the forward button or back button.

9. The multi-region control panel of claim 1 wherein a front face is dimensioned to facilitate handheld operation.

10. The multi-region control panel of claim 9 wherein the front face dimensions are less than about 10 inches on either side.

11. The multi-region control panel of claim 10 wherein the front face dimensions are about 8 inches by 7 inches.

12. The multi-region control panel of claim 10 wherein the control panel body has a thickness of less than about two inches.

13. The multi-region control panel of claim 1 further comprising a mounting bracket for mounting to a rail of a patient table.

14. The multi-region control panel of claim 13 wherein the mounting bracket comprises a screw clamp.

15. The multi-region control panel of claim 1 having a weight of about one kilogram or less.
