Abstract

This invention provides a simple user interface and sequencing viewing method for a mammography interpretation workstation. In particular, the invention includes the method and apparatus that moves the source images and the associated data using two-level of pre-fetching and caching mechanism, sequences the reading workflow (including worklist, hanging protocol, viewing sequencing), draws markup using electronic grease pan, and automatically generates the recall forms and screening reports. The user interface operates on single button and mouse wheel style to maximize the radiologists'"'"' efficiency.

Claims

1. A mammography workstation comprising:

at least one computer display;

a computer processor connected to the at least one computer display, the computer processor also connected to a local memory storage device and a Digital Imaging and Communications in Medicine (DICOM) service;

a workstation application running on the computer processor, the workstation application configured to provide a user interface to be displayed on the at least one computer display, the user interface comprising a viewing sequence configuration interface that includes a plurality of selectable buttons, the selection of which results in a stepped viewing sequence of mammogram images arranged in hanging protocols, the stepped viewing sequence including at least one standard 4-view mammogram, at least one 2-view mammogram, at least one comparison view, and a bilateral mammogram image with an overlaid viewing mask; and

at least one input device suitable to allow a user to select desired buttons of the plurality of selectable buttons and to allow a user to step through the stepped viewing sequence of mammogram images according to the stepped viewing sequence created using the viewing sequence configuration interface.

2. The workstation of claim 1, wherein the at least one input device comprises a computer mouse with a scrolling mechanism and/or a computer keyboard.

3. The workstation of claim 2, wherein the viewing sequencing configuration interface comprises:

a viewing sequence step selection field, the viewing sequence step selection field including a plurality of selectable viewing step buttons; and

a hanging protocol selection field, the hanging protocol selection field including a plurality of mammogram image buttons, each of the plurality of mammogram image buttons displaying an associated one of a plurality of mammogram images, each of the plurality of mammogram images being arranged in a hanging protocol.

4. The workstation of claim 3, wherein the plurality of selectable viewing step buttons comprises:

an overall viewing step button, the selection by the user of the overall viewing step button causing the at least one standard 4-view mammogram to be included in the stepped viewing sequence;

an image quality assessment button, the selection by the user of the image quality assessment button causing the at least one 2-view mammogram and a quality assurance check list to be included in the stepped viewing sequence;

a current-prior comparison button, the selection by the user of the current-prior comparison button causing the at least one comparison view to be included in the stepped viewing sequence, the comparison view presenting a current mammogram and a corresponding prior mammogram simultaneously;

a systematic perception view button, the selection by the user of the systematic perception view button causing the bilateral mammogram image with an overlaid viewing mask to be included in the stepped viewing sequence;

a full resolution view button, the selection by the user of the full resolution view button causing a display of a portion of at least one mammogram in which one pixel of the mammogram is displayed by one pixel on the at least one computer display to be included in the stepped viewing sequence; and

a review and report button, the selection by the user of the review and report button enabling a user to mark areas of diagnostic concern on those images of the plurality of mammogram images that are selection for inclusion in the stepped viewing sequence, the user enable to mark those images with the at least one input device and causing the areas of diagnostic concern to be included in an automatically generated report created at the end of the viewing sequence.

5. The workstation of claim 4, wherein the plurality of mammogram image buttons comprises:

a plurality of standard 4-view mammogram image buttons;

a plurality of 2-view mammogram image buttons;

a plurality of comparison view buttons;

a plurality of bilateral view buttons, each of the plurality of bilateral view buttons including a viewing mask;

a plurality of full resolution buttons; and

a plurality of matched view buttons, each of the matched view buttons including a bilateral craniocaudal mammogram and a bilateral mediolateral oblique mammogram.

6. The workstation of claim 5, wherein each of the plurality of mammogram image buttons comprises a thumbnail view of a corresponding mammogram image associated with each mammogram image button, the selection of any of the plurality of mammogram image buttons causing the corresponding image to be included in the stepped viewing sequence.

7. The workstation of claim 6, wherein the computer processor generates the stepped viewing sequence of mammogram images after the user has completed selections using the viewing sequence configuration interface.

8. The workstation of claim 4, further comprising:

a pre-fetch manager, the pre-fetch manager accessing the DICOM service to retrieve the plurality of mammogram images and storing the plurality of mammogram images on the local memory storage device; and

a cache manager, the cache manager configured to place the plurality of mammogram images or a subset thereof on a computer cache connected to the computer processor.

9. The workstation of claim 8, wherein:

the workstation application is configured to provide a workflow navigation interface, the workflow navigation interface comprising a list of cases to be reviewed by the user;

the pre-fetch manager is configured to access, retrieve, and locally store a next plurality of mammogram images through the DICOM service, the next plurality of mammogram images being associated with a next case on the list of cases that has not been reviewed and is not being reviewed currently by the user; and

the cache manager is configured to place the next plurality of mammogram images on the computer cache before the next case is reviewed by the user.

10. The workstation of claim 1, wherein the viewing mask to be presented over a bilateral mammogram image comprises:

a mask layer, the mask layer being superimposed over the bilateral mammogram image and visually obscuring the bilateral mammogram image; and

a viewing mask window, the viewing mask window being a parallelogram that causes an area contained by the parallelogram to appear unobscured by the mask layer.

11. The workstation of claim 10, wherein the parallelogram of the viewing mask window is definable by the user in terms of an angle of orientation, geometric dimensions, and in terms of position relative to the bilateral mammogram image visually underlying the mask layer.

12. The workstation of claim 11, wherein the viewing mask window comprises an additional parallelogram if the angle of orientation defined by the user is not horizontal, the parallelogram and the additional parallelogram having corresponding geometric dimensions and being jointly positioned by the user relative to the bilateral mammogram image.

13. The workstation of claim 12, wherein the bilateral mammogram image comprises a right mediolateral oblique (MLO) view and a left MLO view, the parallelogram being superimposed over the right MLO view and the additional parallelogram is superimposed over the left MLO view.

14. The workstation of claim 13, wherein the parallelogram is aligned to the pectoral muscle in the right MLO view and the additional parallelogram is aligned to the pectoral muscle in the left MLO view.

15. The workstation of claim 14, wherein the parallelogram is moveable from the pectoral muscle in the right MLO view toward a nipple in the right MLO view and the additional parallelogram is moveable from the pectoral muscle in the left MLO view toward a nipple in the left MLO view.
