Abstract

An ultrasound device acquires ultrasound image data corresponding to a plurality of volume frames of an object and applies morphing or motion compensation to the acquired ultrasound image data to track a particular region of the object. The ultrasound device compounds the motion compensated ultrasound image data that corresponds to the tracked particular region of the object within the plurality of volume frames of the object. The ultrasound device generates a stationary single three dimensional (3D) volume of the tracked particular region of the object. The ultrasound device acquires the ultrasound image data over at least a portion of a movement cycle. The ultrasound device generates motion tracking information and speckle tracking information from the acquired ultrasound image data for the tracked particular region of the object and group pixels corresponding to the tracked particular region of the object based on the generated motion tracking and speckle tracking information.

First claim

What is claimed is:

1. A method, comprising:
acquiring ultrasound image data corresponding to a plurality of subsequent volume frames of an object;
applying motion compensation to said acquired ultrasound image data to track, or align between frames, any particular region of said object within said plurality of volume frames of said object;
compounding said motion compensated ultrasound image data that corresponds to said tracked particular region of said object within said plurality of volume frames of said object; and
generating a stationary single three dimensional (3D) volume of a plurality of said tracked particular regions of said object.

2. The method according to claim 1 , comprising acquiring said ultrasound image data over at least a portion of a movement cycle corresponding to said plurality of volume frames of said object.

3. The method according to claim 1 , comprising generating motion tracking information from said acquired ultrasound image data for said tracked particular regions of said object.

4. The method according to claim 3 , comprising generating speckle tracking information from said acquired ultrasound image data for said tracked particular regions of said object.

5. The method according to claim 4 , comprising grouping pixels corresponding to each of said tracked particular region of said object based on said generated motion tracking information, and based on said generated speckle tracking information.

6. The method according to claim 5 , comprising combining said grouped pixels corresponding to said each of said tracked particular region of said object.

7. The method according to claim 6 , wherein said combining utilizes one or more of an averaging function, a median filtering function, and a maximum and minimum values function.

8. The method according to claim 6 , comprising displaying said stationary single three dimensional (3D) volume of said tracked particular region of said object based on said combined grouping of said pixels corresponding to said tracked particular region of said object.

9. The method according to claim 6 , comprising rendering a three dimensional (3D) visualization of said tracked particular region of said object based on sliced portions of said grouped pixels corresponding to said tracked particular region of said object.

10. A system, comprising:
an ultrasound device, said ultrasound device be operable to:
acquire ultrasound image data corresponding to a plurality of volume frames of an object;
apply motion compensation to said acquired ultrasound image data to track, or align between frames, a particular region of said object within said plurality of volume frames of said object;
compound said motion compensated ultrasound image data that corresponds to said tracked particular region of said object within said plurality of volume frames of said object; and
generate a stationary single three dimensional (3D) volume of a plurality of said tracked particular regions of said object.

11. The system according to claim 10 , wherein said ultrasound device is operable to acquire said ultrasound image data over at least a portion of a movement cycle corresponding to said plurality of volume frames of said object.

12. The system according to claim 10 , wherein said ultrasound device is operable to generate motion tracking information from said acquired ultrasound image data for said tracked particular region of said object.

13. The system according to claim 12 , wherein said ultrasound device is operable to generate speckle tracking information from said acquired ultrasound image data for said tracked particular region of said object.

14. The system according to claim 13 , wherein said ultrasound device is operable to group pixels corresponding to each of said tracked particular region of said object based on said generated motion tracking information, and based on said generated speckle tracking information.

15. The system according to claim 14 , wherein said ultrasound device is operable to combine said grouped pixels corresponding to said each of said tracked particular region of said object.

16. The system according to claim 15 , wherein said combining utilizes one or more of an averaging function, a median filtering function, and a maximum and minimum values function.

17. The system according to claim 15 , wherein said ultrasound device is operable to display said stationary single three dimensional (3D) volume of said tracked particular region of said object based on said combined grouping of said pixels corresponding to said tracked particular region of said object.

18. The system according to claim 15 , wherein said ultrasound device is operable to render a three dimensional (3D) visualization of said tracked particular region of said object based on sliced portions of said grouped and compounded pixels corresponding to said tracked particular region of said object.

19. A non-transitory computer readable medium having stored thereon, a computer program having at least one code section, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
acquiring ultrasound image data corresponding to a plurality of volume frames of an object;
applying motion compensation to said acquired ultrasound image data to track, or align between frames, a particular structure in said object within said plurality of volume frames of said object;
compounding said motion compensated ultrasound image data that corresponds to said tracked particular structure in said object within said plurality of volume frames of said object; and
generating a stationary single three dimensional (3D) volume of said tracked particular structure in said object.

20. The non-transitory computer readable medium according to claim 19 , comprising morphing at least a portion of said plurality of volume frames of said object to track said particular structure in said object, wherein said morphing is based on motion tracking information and speckle tracking information generated from said acquired ultrasound image data.
