Abstract

The systems and methods described herein generally relate to automatically determining an anatomical measurement of an ultrasound image. The systems and methods identify a view characteristic of an ultrasound image. The ultrasound image including one or more anatomical features. The systems and methods select a diagnostic measurement (DM) tool based on the view characteristic, on a graphical user interface (GUI), which is generated on a display. The systems and methods receive a first selection at a first position within the ultrasound image, and automatically determine an anatomical measurement, to be performed upon the ultrasound image utilizing the DM tool, based on the first position.

First claim

What is claimed is:

1. A computer implemented method, comprising:
identifying a view characteristic of an ultrasound image, wherein the ultrasound image includes one or more anatomical features;
receiving a first selection at a first position within the ultrasound image;
automatically identifying a select contextual indicator based on the view characteristic and the first position;
selecting a diagnostic measurement (DM) tool based on the select contextual indicator which is generated on a display;
automatically determining an anatomical measurement, to be performed upon the ultrasound image utilizing the DM tool, based on the select contextual indicator and wherein the contextual indicator corresponds to one or more characteristics of an ultrasound image relative to the first selection.

2. The computer implemented method of claim 1 , wherein the DM tool has an associated set of contextual indicators that correspond to different types of anatomical measurements, the determining operation including identifying a select contextual indicator indicating a type of anatomical measurement to be obtained from the first selection.

3. The computer implemented method of claim 2 , wherein the select contextual indicator includes at least one of i) a first anatomical feature proximate to the first position, ii) the view characteristic, or iii) a phase in a cardiac cycle at which the ultrasound image was obtained.

4. The computer implemented method of claim 1 , further comprising receiving a second selection at a second position within the ultrasound image subsequent to the first selection, the select contextual indicator automatically identified based, in part, on a relation between the first and second selections.

5. The computer implemented method of claim 4 , further comprising calculating a distance between the first and second positions, wherein the distance is indicative of a length anatomical measurement or an area anatomical measurement, wherein the area anatomical measurement is indicative of a non-linear trace.

6. The computer implemented method of claim 4 , further comprising identifying a first anatomical feature proximate to the first position and a second anatomical feature proximate to the second position, wherein the determining operation identifies the anatomical measurement when the first and second anatomical features are the same.

7. The computer implemented method of claim 1 , wherein the determining operation includes identifying the first position relative to the first anatomical feature.

8. The computer implemented method of claim 1 , further comprising selecting the DM tool from a set of DM tools based on the first position.

9. The computer implemented method of claim 1 , further comprising generating an anatomical measurement label indicative of the anatomical measurement, and displaying the anatomical measurement label concurrently with the ultrasound image on a display.

10. The computer implemented method of claim 1 , wherein the view characteristic comprises a characteristic vector that represents an array of information that describes at least one of a group of pixels or a group of voxels.

11. A medical imaging system comprising:
an ultrasound probe configured to acquire ultrasound data of an anatomical structure;
a display; and
a controller circuit configured to:
identify a view characteristic of an ultrasound image, wherein the ultrasound image includes one or more anatomical features;
receive a first selection at a first position within the ultrasound image;
automatically identify a select contextual indicator based on the view characteristic and the first position;
select a diagnostic measurement (DM) tool based on the select contextual indicator which is generated on the display;
automatically determine an anatomical measurement, to be performed upon the ultrasound image utilizing the DM tool, based on the select contextual indicator and wherein the contextual indicator corresponds to one or more characteristics of an ultrasound image relative to the first selection.

12. The medical imaging system of claim 11 , wherein the DM tool has an associated set of contextual indicators that correspond to different types of anatomical measurements, the determining operation including identifying a select contextual indicator indicating a type of anatomical measurement to be obtained from the first selection.

13. The medical imaging system of claim 12 , wherein the select contextual indicator includes at least one of i) a first anatomical feature proximate to the first position, ii) the view characteristic, or iii) a phase in a cardiac cycle at which the ultrasound image was obtained.

14. The medical imaging system of claim 11 , wherein the controller circuit is configured to receive a second selection at a second position within the ultrasound image subsequent to the first selection.

15. The medical imaging system of claim 14 , wherein the controller circuit is configured to calculate a distance between the first and second positions, wherein the distance is indicative of a length anatomical measurement or an area anatomical measurement, wherein the area anatomical measurement is indicative of a non-linear trace.

16. The medical imaging system of claim 14 , wherein the controller circuit is configured to identify a first anatomical feature proximate to the first position and a second anatomical feature proximate to the second position, wherein the controller circuit is configured to identify the anatomical measurement when the first and second anatomical features are the same.

17. The medical imaging system of claim 11 , wherein the controller circuit is configured to identify the first position relative to the first anatomical feature.

18. The medical imaging system of claim 11 , wherein the controller circuit is configured to select the DM tool from a set of DM tools based on the first position.

19. The medical imaging system of claim 11 , wherein the controller circuit is configured to generate an anatomical measurement label indicative of the anatomical measurement, and display the anatomical measurement label concurrently with the ultrasound image on a display.

20. The medical imaging system of claim 11 , wherein the view characteristic comprises a characteristic vector that represents an array of information that describes at least one of a group of pixels or a group of voxels.

21. A computer implemented method, comprising:
identifying a view characteristic of an ultrasound image, wherein the ultrasound imaging includes one or more anatomical features;
receiving a first selection at a first position within the ultrasound image and a second selection at a second position within the ultrasound image;
automatically identifying a select contextual indicator based on the view characteristic, the first position and the second position;
selecting a diagnostic measurement (DM) tool based on the select contextual indicator wherein the DM tool has an associated set of contextual indicators that correspond to different types of anatomical measurements;
identifying a select contextual indicator indicating a type of anatomical measurement to be obtained from the first and second selections;
automatically determining an anatomical measurement, to be performed upon the ultrasound image utilizing the DM tool, based on the select contextual indicator and wherein the contextual indicator corresponds to one or more characteristics of an ultrasound image relative to the first selection.
