Abstract

A method and apparatus for providing a “just-in-time” localizer image of an object of interest from which a high resolution image can be based is disclosed herein. The “just-in-time” localizer image is acquired based on at least one of a default localizer image of the object of interest, a precursor image of the object of interest, and a representation of a three-dimensional volume data set associated with the object of interest. The “just-in-time” localizer image and the high resolution image are prescribed, acquired, and displayed within a single graphical prescription environment.

Claims

1. A method for generating a clinically useful image having a desired image acquisition plane in a short time frame, the method comprising the steps of:

prescribing a second image relative to at least one of a default second image, a first image, and a representation of a three-dimensional volume data set;

acquiring the second image;

displaying the second image;

prescribing the clinically useful image relative to the second image;

acquiring the clinically useful image; and

displaying the clinically useful image,

wherein the second image and the clinically useful image are prescribed, acquired, and displayed within a single graphical prescription environment included in an imaging system.

2. The method of claim 1, wherein the default second image is an image acquired at an operator specified default location and orientation within an object of interest or at a landmark position within the object of interest.

3. The method of claim 1, wherein an image resolution associated with the clinically useful image is greater than an image resolution associated with the second image.

4. The method of claim 3, wherein the image resolution associated with the second image is greater than an image resolution associated with the first image.

5. The method of claim 1, wherein the first image is an image acquired in real-time and updated continuously within the single graphical prescription environment.

6. The method of claim 1, wherein the acquisition of the second image and the first image are interleaved with each other.

7. The method of claim 1, wherein prescribing a second image includes prescribing a localization image acquisition plane associated with the second image.

8. The method of claim 7, wherein prescribing the clinically useful image includes prescribing the desired image acquisition plane of the clinically useful image, wherein the desired image acquisition plane and the localization image acquisition plane are identical to each other.

9. The method of claim 1, further comprising acquiring a plurality of second images based on the first image, the first image including a point and a plurality of image acquisition planes being associated with the plurality of second images.

10. The method of claim 9, wherein the point on the first image is an intersection point of the plurality of image acquisition planes associated with the plurality of second images.

11. The method of claim 9, wherein at least one of the image acquisition planes is non-intersecting with respect to another of the image acquisition planes.

12. The method of claim 1, wherein prescribing a second image includes prescribing a two-dimensional slice within the representation of the three-dimensional volume data set.

13. The method of claim 12, wherein acquiring the second image includes reformatting the two-dimensional slice, the reformatted two-dimensional slice being the second image.

14. An imaging system for generating a clinically useful image having a desired image acquisition plane in a short time frame, the system comprising:

means for prescribing a second image relative to at least one of a default second image, a first image, and a representation of a three-dimensional volume data set;

means for acquiring the second image;

means for displaying the second image;

means for prescribing the clinically useful image relative to the second image;

means for acquiring the clinically useful image; and

means for displaying the clinically useful image,

wherein the second image and the clinically useful image are prescribed, acquired, and displayed within a single graphical prescription environment included in the imaging system.

15. The system of claim 14, wherein the default second image is an image acquired at an operator specified default location and orientation within an object of interest or at a landmark position within the object of interest.

16. The system of claim 14, wherein an image resolution associated with the clinically useful image is greater than an image resolution associated with the second image.

17. The system of claim 16, wherein the image resolution associated with the second image is greater than an image resolution associated with the first image.

18. The system of claim 14, wherein the first image is an image acquired in real-time and updated continuously within the single graphical prescription environment.

19. The system of claim 14, wherein acquisition of the second image and the first image are interleaved with each other.

20. The system of claim 14, wherein the means for prescribing a second image is configured to prescribe a localization image acquisition plane associated with the second image.

21. The system of claim 20, wherein the means for prescribing the clinically useful image is configured to prescribe the desired image acquisition plane of the clinically useful image, wherein the desired image acquisition plane and the localization image acquisition plane are identical to each other.

22. The system of claim 14, further comprising means for acquiring a plurality of second images based on the first image, the first image including a point and a plurality of image acquisition planes being associated with the plurality of second images.

23. The system of claim 22, wherein the point on the first image is an intersection point of the plurality of image acquisition planes associated with the plurality of second images.

24. The system of claim 22, wherein at least one of the image acquisition planes is non-intersecting with respect to another of the image acquisition planes.

25. The system of claim 14, wherein the means for prescribing a second image is configured to prescribe a two-dimensional slice within the representation of the three-dimensional volume data set.

26. The system of claim 25, wherein the means for acquiring the second image is configured to reformat the two-dimensional slice, the reformatted two-dimensional slice being the second image.
