Abstract

An interactive user assistant for imaging processes analyzes medical image data pertaining to regions of interest. The user assistant compares displayed medical images and/or the data underlying the medical images with expected medical image data. The user assistant identifies whether or not the displayed medical image meets expectations or is plausible. The user assistant may use previously analyzed data in determining whether the displayed medical image is as expected. If the displayed medical image does not meet expectations, the user assistant determines whether or not the cause of the disagreement between the displayed and expected images is ascertainable. If the cause of the disparity between the images is ascertainable, the user assistant presents specific recommendations. If the cause of the disparity between the images is not ascertainable, the user assistant presents general suggestions.

Claims

1. A data processing system for providing an interactive user assistant for imaging processes, the system comprising:

a memory unit operable to store expected medical image data;

a processing unit operable to compare a displayed medical image and the data underlying the displayed medical image with the expected medical image data and determine if the displayed medical image is plausible; and

a user interface operable to display the displayed medical image and present information based upon the determination of whether the displayed medical image is plausible.

2. The system of claim 1, wherein if the displayed medical image is not plausible, the processing unit attempts to ascertain the reason that the displayed medical image is not plausible.

3. The system of claim 2, wherein if the processing unit ascertains the reason that the displayed medical image is not plausible, the user interface presents recommendations specific to the reason ascertained.

4. The system of claim 3, wherein the user interface is operable to alter the displayed medical image and the processing unit ascertains that the reason that the displayed medical image is not plausible is due to erroneous operation of the user interface.

5. The system of claim 3, wherein the processing unit ascertains that the displayed medical image is not plausible based upon analysis of the blood flow through a region of interest.

6. The system of claim 3, wherein the processing unit ascertains that the displayed medical image is not plausible based upon analysis of blood volume in a region of interest.

7. The system of claim 3, wherein the processing unit ascertains that the displayed medical image is not plausible based upon analysis of time to peak enhancement of a region of interest.

8. The system of claim 3, wherein the processing unit ascertains that the displayed medical image is not plausible based upon analysis of the mean transit time of a contrast agent through a region of interest.

9. The system of claim 3, wherein the processing unit ascertains that the displayed medical image is not plausible based upon analysis of one or more, or any functional combination, of the blood flow through a region of interest, the blood volume in a region of interest, the time to peak enhancement of a region of interest, and the mean transit time of a contrast agent through a region of interest.

10. The system of claim 2, wherein if the processing unit does not ascertain the reason that the displayed medical image is not plausible, the display presents general recommendations based upon the displayed medical image.

11. A data processing system for providing an interactive user assistant for imaging processes, the system comprising:

a processing unit operable to generate medical image data pertaining to internal images of a patient;

a display operable to reproduce the internal images from the medical image data; and

a user interface operable to alter the presentation of the medical image data on the display, wherein the processing unit identifies an erroneous presentation of the medical image data.

12. The system of claim 11, wherein the user interface presents a recommendation to correct the erroneous presentation of the medical image data.

13. The system of claim 12, wherein the processing unit identifies that the presentation of the medical image data is erroneous based upon analysis of blood flow through a region of interest.

14. The system of claim 12, wherein the processing unit identifies that the presentation of the medical image data is erroneous based upon the blood volume in a region of interest.

15. The system of claim 12, wherein the processing unit identifies that the presentation of the medical image data is erroneous based upon the time to peak enhancement of a region of interest.

16. The system of claim 12, wherein the processing unit identifies that the presentation of the medical image data is erroneous based upon the mean transmit time of a contrast agent through a region of interest.

17. The system of claim 12, comprising:

a memory unit operable to store expected data, wherein the processing unit compares the medical image data of a patient with the expected data to determine whether the presentation of the medical image data is erroneous.

18. The system of claim 17, wherein the user interface is operable to present graphical and textual medical information on the display, the medical information includes training instructions that facilitate learning how to operate the user interface.

19. A method for providing an interactive user assistant for imaging processes, the method comprising:

obtaining images of a region of interest after administration of a contrast agent;

generating contrast enhancement data from the images; and

automatically determining if the contrast enhancement data is plausible.

20. The method of claim 19, comprising:

determining a recommendation regarding further action if the contrast enhancement data is not as expected; and

presenting the recommendation on a display.

21. The method of claim 20, wherein the determination of whether the contrast enhancement data is plausible is based upon previously analyzed images of a region of interest.

22. The method of claim 20, wherein the determination of whether the contrast enhancement data is plausible is based upon previously analyzed data that includes data pertaining to the medical history of a patient.

23. A computer-readable medium having instructions executable on a computer stored thereon, the instructions comprising:

receiving medical image data pertaining to internal medical images of a patient;

presenting the medical images on a display;

providing a user interface operable to alter the presentation of the medical images on the display; and

determining whether the presentation of the medical images on the display is erroneous.

24. The computer-readable medium of claim 23, the instructions comprising determining that the presentation of the medical images on the display is erroneous because of erroneous operation of the user interface.

25. The computer-readable medium of claim 23, the instructions comprising determining that the presentation of the medical images on the display is erroneous based upon analysis of blood flow through a region of interest.

26. The computer-readable medium of claim 23, the instructions comprising determining that the presentation of the medical images on the display is erroneous based upon analysis of the blood volume in a region of interest.

27. The computer-readable medium of claim 23, the instructions comprising determining that the presentation of the medical images on the display is erroneous based upon analysis of time to peak enhancement of a region of interest.

28. The computer-readable medium of claim 23, the instructions comprising determining that the presentation of the medical images on the display is erroneous based upon analysis of the mean transit time of a contrast agent through a region of interest.
