Abstract

A mechanical ventilation device comprising at least one electronic controller is configured to receive images of lungs of a patient undergoing mechanical ventilation therapy with a mechanical ventilator, the images being acquired over time and having timestamps; process the images to generate timeline images at corresponding discrete time points; and display a timeline of the timeline images on a display device.

First claim

The invention claimed is:

1. A mechanical ventilation device comprising at least one electronic controller configured to:
receive images of lungs of a patient undergoing mechanical ventilation therapy with a mechanical ventilator, the images being acquired over time and having timestamps;
process the images to generate timeline images at corresponding discrete time points;
display a scrollable timeline of the timeline images in a time window on a display device; and
receive a user input from a user to dynamically adjust the time window; wherein the displayed scrollable timeline further includes a selectable option to receive a user input to select a stiffness degree of an image registration between adjacent images in the timeline.

2. A mechanical ventilation method comprising, with at least one electronic controller:
receiving images of lungs of a patient undergoing mechanical ventilation therapy with a mechanical ventilator, the images being acquired over time and having timestamps;
processing the images to generate timeline images at corresponding discrete time points;
displaying a timeline of the timeline images on a display device, wherein the displayed timeline is a scrollable timeline including the timeline images in a time window;
wherein the timeline further includes a selectable option to receive a user input to select a stiffness degree of an image registration between adjacent images in the timeline.

3. The device of claim 1 , wherein the at least one electronic controller is configured to process the images to generate the timeline images by operations including one or more of:
aligning the images to a reference viewpoint;
normalizing grayscale values of the images;
performing deformable image registration (DIR) of the images; and
interpolating the images to generate the timeline images at discrete time points separated by a predetermined fixed time interval.

4. The device of claim 1 , wherein the at least one electronic controller is further configured to:
receive a user selection of a timeline image of the displayed timeline via a user input device; and
in response to the user selection, display an image of the received images whose timestamp is closest to the discrete time point of the user-selected timeline image.

5. The device of claim 1 , wherein the at least one electronic controller is further configured to:
receive values of at least one ventilator setting of the mechanical ventilation therapy as a function of time; and
annotate the displayed timeline images on the display device with the values of the at least one ventilator setting corresponding in time to the displayed timeline images.

6. The device of claim 1 , wherein the timeline includes an endpoint, and the at least one electronic controller is programmed to:
receive a user input of a future discrete time point on the timeline that is past an endpoint of the timeline;
generate an extrapolated image for the future discrete time point; and
display the extrapolated image at the future discrete time point on the displayed timeline.

7. The device of claim 6 , further comprising a database storing treatment data of historical patients, wherein the extrapolated image is generated using the treatment data.

8. The device of claim 1 , wherein the display of the timeline includes a slider displayed on the display device, the slider configured to receive the user input.

9. The method of claim 2 , wherein the processing the images to generate timeline images at corresponding discrete time points includes the at least one electronic controller performing one or more of the following:
aligning the images to a reference viewpoint;
normalizing grayscale values of the images;
performing deformable image registration (DIR) of the images; and
interpolating the images to generate the timeline images at discrete time points separated by a predetermined fixed time interval.

10. The method of claim 2 , further comprising the at least one electronic controller:
receiving a user selection of a timeline image of the displayed timeline via a user input device; and
in response to the user selection, displaying an image of the received images whose timestamp is closest to the discrete time point of the user-selected timeline image.

11. The method of claim 2 , further comprising the at least one electronic controller:
receiving values of at least one ventilator setting of the mechanical ventilation therapy as a function of time; and
annotating the displayed timeline images on the display device with the values of the at least one ventilator setting corresponding in time to the displayed timeline images.

12. The method of claim 2 , wherein the timeline includes an endpoint, and further comprising the at least one electronic controller:
receiving a user input of a future discrete time point on the timeline that is past an endpoint of the timeline;
generating an extrapolated image for the future discrete time point; and
displaying the extrapolated image at the future discrete time point on the displayed timeline.

13. The method of claim 12 , wherein the extrapolated image is generated using treatment data of historical patients.

14. The method of claim 2 , wherein the displaying of the timeline includes displaying a slider on the display device to receive the user input.
