Abstract

A method of conducting a medical workflow with a touch-sensitive bedside controller is disclosed. The method includes initiating a medical workflow using a graphical user interface on the bedside controller, positioning an imaging tool within a patient'"'"'s body based on images captured by the imaging tools and displayed on the bedside controller, controlling the commencement and termination of a recordation of images captured by the imaging tool using the graphical user interface on the bedside controller, navigating through the recorded images to identify an image of interest using the graphical user interface on the bedside controller, and performing measurements on the image of interest using the graphical user interface on the bedside controller.

Claims

1. A method of conducting a medical workflow with a touch-sensitive bedside controller, the method comprising:

initiating a medical workflow using a graphical user interface on the bedside controller;

positioning an imaging tool within a patient'"'"'s body based on images captured by the imaging tools and displayed on the bedside controller;

controlling the initiation and termination of a recordation of images by the imaging tool using the graphical user interface on the bedside controller;

navigating through the recorded images to identify an image of interest using the graphical user interface on the bedside controller; and

performing measurements on the image of interest using the graphical user interface on the bedside controller.

2. The method of claim 1, wherein the initiating includes selecting the medical workflow out of a plurality of medical workflows presented as selectable options within the graphical user interface.

3. The method of claim 2, wherein the plurality of medical workflows includes two or more of an intravascular ultrasound (IVUS) imaging workflow, an intravascular photoacoustic (IVPA) imaging workflow, an optical coherence tomography (OCT) workflow, a forward looking IVUS (FL-IVUS) workflow, a fractional flow reserve (FFR) workflow, a coronary flow reserve (CFR) workflow, and an angiography workflow.

4. The method of claim 1, wherein the performing measurements includes touching and releasing portions of the image of interest as it is displayed on the bedside controller to make one of an area measurement and a diameter measurement.

5. The method of claim 4, wherein the touching and releasing includes making one of the area measurement and the diameter measurement without first selecting a measurement mode corresponding one of the area measurement and the diameter measurement.

6. The method of claim 1, wherein the initiating, positioning, controlling, navigating, and performing are performed on the bedside controller in a sterile field.

7. The method of claim 1, wherein navigating through the recorded images includes navigating through a condensed view of all of the recorded images.

8. The method of claim 1, wherein navigating through the recorded images includes performing navigation-type gestures on the touch-sensitive display.

9. The method of claim 1, wherein performing measurements includes annotating the image of interest with the measurements.

10. The method of claim 9, further including saving to a processing system the image of interest with the measurement annotations thereon.

11. The method of claim 1, wherein the imaging tool is a sensor disposed on a catheter within a vessel of the patient.

12. The method of claim 11, wherein the controlling includes coordinating the recordation with a pullback of the catheter.

13. The method of claim 1, wherein controlling the initiation and termination includes selecting a record option in the graphical user interface to initiate the recordation.

14. The method of claim 1, further including receiving haptic feedback in response to performing measurements on the image of interest using the graphical user interface.

15. The method of claim 1, wherein the images captured by the imaging tool are associated with one of intravascular ultrasound (IVUS), intravascular photoacoustic (IVPA), optical coherence tomography (OCT), forward looking IVUS (FL-IVUS), fractional flow reserve (FFR), coronary flow reserve (CFR), and angiography.

16. A bedside controller, comprising:

a housing;

a touch-sensitive display disposed within a surface of the housing and configured to display images and receive user input on the surface;

a processor disposed within the housing;

a communication module disposed within the housing, communicatively coupled to the processor, and configured to transmit and receive medical data; and
