Abstract

A system (100) includes an echocardiogram measurement tool (150) that determines a subset (152) of measurements from a list of echocardiogram measurements according to a view of an ultrasound imaging sequence (110) and a mapping (154) between the view and the subset of measurements.

First claim

The invention claimed is:

1. A method, comprising:
storing a mapping that maps each image view of a plurality of different image views to one or more types of measurements of a plurality of different types of measurements, wherein the one or more types of measurements for a particular image view of the plurality of different image views are applicable to be computed from the particular image view and represent a subset of the plurality of different types of measurements;
determining the subset of the plurality of different types of measurements for the particular image view from the mapping, wherein measurements of the plurality of different types of measurements not in the subset are not applicable to an anatomy in the particular image view;
displaying the particular image view and the determined subset of the plurality of different types of measurements with a display, wherein the plurality of different types of measurements are displayed in a user selectable list;
receiving an input selecting one of the displayed types of measurements in the list; and
computing a value for the selected type of measurement based on the anatomy in the particular image view, wherein the different types of measurements are used to one or more of monitor or diagnose one or more of a heart disease or a heart condition.

2. The method according to claim 1 , further including:
mapping each of the image views to the anatomy in the particular image view; and
displaying the particular image view, comprising the determined subset of the plurality of different types of measurements and the anatomy.

3. The method according to claim 1 , wherein the image view includes pixels that represent at least a left ventricle of a heart of a subject and the selected type of measurement is left ventricular ejection fraction.

4. The method according to claim 3 , wherein the subset of the type of measurements does not include a diameter of an inferior vena cava of the heart of the subject, wherein the particular image view does not include pixels that represent the inferior vena cava of the heart of the subject.

5. A non-transitory computer readable medium encoded with computer readable instructions, which, when executed by a processor, cause the processor to:
store a mapping that maps each image view of a plurality of different image views to one or more types of measurements of a plurality of different types of measurements, wherein the one or more types of measurements for a particular image view of the plurality of different image views are applicable to be computed from the particular image view and represent a subset of the plurality of different types of measurements;
determine the subset of the plurality of different types of measurements for the particular image view from the mapping, wherein measurements of the plurality of different types of measurements not in the subset are not applicable to an anatomy in the particular image view;
display the particular image view and the determined subset of the plurality of different types of measurements with a display, wherein the plurality of different types of measurements are displayed in a user selectable list;
receive an input selecting one of the displayed types of measurements in the list; and
compute a value for the selected type of measurement based on the anatomy in the particular image view, wherein the different types of measurements are used to one or more of monitor or diagnose one or more of a heart disease or a heart condition.

6. The non-transitory computer readable medium of claim 5 , wherein executing the computer readable instructions further cause the processor to:
map each of the image views to the anatomy in the particular image view;
display the particular image view, the determined subset of the plurality of different types of measurements, and the anatomy in the particular image view.

7. The non-transitory computer readable medium of claim 5 , wherein executing the computer readable instructions further cause the processor to:
map each of the image views to the anatomy in the particular image view;

determine anatomy in the particular image view; and
determine the subset of the plurality of different types of measurements based on the anatomy in the particular image view.

8. The non-transitory computer readable medium of claim 5 , wherein the particular image view includes pixels that represent at least a left ventricle of a heart of a subject and the selected type of measurement is left ventricular ejection fraction.

9. The non-transitory computer readable medium of claim 8 , wherein the subset of the type of measurements does not include a diameter of an inferior vena cava of the heart of the subject, wherein the particular image view does not include pixels that represent the inferior vena cava of the heart of the subject.

10. A non-transitory computer readable medium encoded with computer readable instructions, which, when executed by a processor, cause the processor to:
determine which measurements from a list of possible echocardiogram measurements are applicable to anatomy in a view of an ultrasound imaging sequence based on a mapping between the view and the possible echocardiogram measurements,
wherein the determined measurements are a subset of the list of possible echocardiogram measurements, and the measurements of the list of possible echocardiogram measurements that are not applicable to any of the anatomy in the view are not included in the subset;
display the determined subset of measurements in a user selectable list and the view of the ultrasound imaging sequence on a user interface displayed on a display device; and
in response to an input selecting one of the displayed subset of measurements, measure an aspect of a heart in the view according to the one selected displayed subset of measurement, wherein the different types of measurements are used to one or more of monitor or diagnose one or more of a heart disease or a heart condition.

11. The non-transitory computer readable medium of claim 10 , wherein executing the computer readable instructions further cause the processor to:
map a first sub-mapping from the view to portions of the heart within the view; and
map a second sub-mapping from the portions of heart anatomy within the view to the subset of measurements.

12. The non-transitory computer readable medium of claim 10 , wherein executing the computer readable instructions further cause the processor to:
display only the determined subset of measurements in the selectable list and not display a remainder of the list of measurements in the selectable list.

13. The non-transitory computer readable medium of claim 10 , wherein executing the computer readable instructions further cause the processor to:
determine the view from an analysis of the ultrasound imaging sequence.

14. The non-transitory computer readable medium of claim 10 , wherein executing the computer readable instructions further cause the processor to:
store the list of echocardiogram measurements as a lookup table that comprises elements representing different measurements according to corresponding views.

15. The non-transitory computer readable medium of claim 14 , wherein executing the computer readable instructions further cause the processor to:
order the displayed subset of measurements according to usability statistics.

16. The non-transitory computer readable medium of claim 10 , wherein executing the computer readable instructions further cause the processor to:
select and apply at least one measurement of the subset of measu
