Abstract

Methods and systems for ultrasound data processing are provided. One method includes acquiring channel ultrasound data from a plurality of channel connected to a plurality of elements of an ultrasound probe and storing the channel ultrasound data from the plurality of channels. The method further includes generating ultrasound images based on processing of the acquired channel ultrasound data and displaying the ultrasound images. The method also includes performing additional processing on the stored channel ultrasound data while the ultrasound images are displayed and displaying updated ultrasound images generated by the additional processing.

First claim

What is claimed is:

1. A method for forming images from ultrasound data, the method comprising:
acquiring channel ultrasound data from a plurality of channels connected to a plurality of elements of an ultrasound probe;
storing the channel ultrasound data from the plurality of channels;
generating first ultrasound images by processing the stored channel ultrasound data, wherein the processing comprises of performing partial beamforming of at least some of the stored channel ultrasound data;
displaying the first ultrasound images during acquisition of the channel ultrasound data;
performing additional processing on the stored channel ultrasound data; and
generating and displaying updated ultrasound images generated by the additional processing, the updated ultrasound images having a higher image quality or resolution as compared to the first ultrasound images displayed before performing the additional processing,
wherein the additional processing comprises of at least performing additional beamforming on the partially beamformed stored channel ultrasound data that was used to generate the first ultrasound images.

2. A method in accordance with claim 1 , wherein the first ultrasound images comprise images having a basic image quality that is lower than higher image quality or resolution.

3. A method in accordance with claim 1 , wherein the stored channel ultrasound data comprises a plurality of image frames and generating the first ultrasound images comprises processing a portion of the plurality of image frames, and performing the additional processing comprises processing additional frames of the plurality of image frames not previously processed and further comprising displaying incrementally updated ultrasound images based on the additional processing performed using the additional image frames.

4. A method in accordance with claim 1 , further comprising storing the acquired channel ultrasound data in a long term memory while processing the acquired channel ultrasound data copied to a short term memory, and further performing a different type of processing on the channel ultrasound data stored in the long term memory.

5. A method in accordance with claim 1 , wherein the additional processing is further performed during display of cine images.

6. A method in accordance with claim 1 , wherein the processing of the stored channel ultrasound data to generate the first images comprises hardware processing and the additional processing comprises software processing.

7. A method in accordance with claim 1 , wherein the processing of the stored channel ultrasound data to generate the first ultrasound images comprises software processing and the additional processing comprises software processing.

8. A method in accordance with claim 1 , wherein the additional processing comprises processing operations exceeding a real-time processing capability of an ultrasound system.

9. A method in accordance with claim 1 , wherein the processing to generate the first ultrasound images comprises a basic beamforming technique that is less advanced than an advanced beamforming technique, and the additional processing comprises the advanced beamforming technique allowing generation of the updated ultrasound images having the higher image quality or resolution.

10. A method in accordance with claim 1 , wherein the additional processing is performed when a processing utilization of an ultrasound system is below a predetermined level.

11. A method in accordance with claim 1 , wherein the displaying updated ultrasound images comprises generating the updated ultrasound images through the additional processing of the stored ultrasound data, wherein the updated ultrasound images relate to the stored ultrasound data.

12. A method for forming images from ultrasound data, the method comprising:
acquiring channel ultrasound data from a plurality of channels connected to a plurality of elements of an ultrasound probe;
storing the channel ultrasound data from the plurality of channels;
forming a pixel image from the stored channel ultrasound data, wherein the pixel image is formed by performing partial beamforming of at least some of the stored channel ultrasound data;
displaying the pixel image;
performing additional processing on the stored channel ultrasound data;
generating an updated ultrasound image by performing the additional processing, the additional processing comprising additional beamforming on the partially beamformed stored channel ultrasound data; and
displaying the updated ultrasound image, wherein the updated ultrasound image has a higher image quality or resolution as compared to the pixel image.

13. A method in accordance with claim 12 , wherein the displaying an updated ultrasound image comprises generating the updated ultrasound image through the additional processing of the stored channel ultrasound data, wherein the updated ultrasound image relates to the stored ultrasound channel data.

14. A method for forming images from ultrasound data, the method comprising:
acquiring channel ultrasound data from a plurality of channels connected to a plurality of elements of an ultrasound probe;
storing the channel ultrasound data from the plurality of channels;
generating ultrasound images based on processing of the acquired channel ultrasound data, wherein the generating comprises performing partial beamforming of at least some of the stored channel ultrasound data;
displaying the ultrasound images;
performing additional processing on the stored channel ultrasound data while the ultrasound images are displayed, wherein the additional processing comprises performing additional beamforming on the partially beamformed stored channel ultrasound data;
generating updated ultrasound images by the additional processing; and
displaying the updated ultrasound images generated by the additional processing.

15. A method in accordance with claim 14 , wherein the ultrasound images comprise images having a first image quality.

16. A method in accordance with claim 14 , wherein the updated ultrasound images comprise images with a second image quality having an increased quality or resolution in relation to the first image quality.

17. A method in accordance with claim 14 , further comprising displaying incrementally updated ultrasound images based on the additional processing performed on additional image frames of the channel ultrasound data.

18. A method in accordance with claim 14 , further comprising performing the processing during a live scanning mode and the additional processing during a replay mode of operation.

19. A method in accordance with claim 14 , further comprising performing a different type of processing on the stored channel ultrasound data.

20. A method in accordance with claim 14 , wherein the additional processing is performed during display of cine images.

21. A method in accordance with claim 14 , wherein the processing of the channel ultrasound data comprises hardware processing and the additional processing comprises software processing.

22. A method in accordance with claim 14 , wherein the processing of the channel ultrasound data comprises software processing and the additional processing comprises software processing.

23. A method in accordance with claim 14 , wherein the additional processing comprises processing operations exceeding a real-time processing capability of the ultrasound system.

24. A method in accordance with c
