The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method comprising:
processing a medical x-ray image in digital form to detect suspected abnormalities;
creating an annotated map of suspected abnormalities detected in said processing;
wherein said map shows both locations of suspected abnormalities and values related to confidence levels that suspected abnormalities are true abnormalities;
said confidence levels being user selectable; and
displaying both the x-ray image and the annotation map to a user.
2. A method as in claim 1 comprising supplying said x-ray image on film and digitizing the film to thereby generate the x-ray image in digital form that is processed in said processing.
3. A method as in claim 1 in which said processing includes converting said digital x-ray image from one digital format to another digital format.
4. A method as in claim 1 including selecting a first threshold of said confidence level and using a first notation to show suspected abnormalities in said map detected in accordance with the first threshold.
5. A method as in claim 4 including selecting an additional, second threshold of said confidence levels, different from the first threshold, and using a second notation, different from said first notation, to show suspected abnormalities detected in accordance with the second threshold.
6. A method as in claim 5 including selecting a third threshold, different from said first and second thresholds, and using a third notation, different from said first and second notations, to show suspected abnormalities detected in accordance with the third threshold.
7. A method as in claim 1 in which said map shows said values related to confidence levels as numerical values.
8. A method as in claim 1 in which said map shows said values related to confidence levels as different colors for different ranges of values.
9. A method as in claim 1 in which said map shows said values related to confidence levels as location markers that are differently sized in accordance with said values.
10. A method as in claim 1 in which said displaying comprises displaying said x-ray image on film at a lightbox and displaying an annotated map corresponding thereto at a monitor below and adjacent the displayed film.
11. A method as in claim 10 in which said displaying comprises displaying a reduced size version of the x-ray image superimposed and registered with said map at said monitor.
12. A method as in claim 1 in which said displaying comprises displaying said x-ray image in digital form at a monitor and displaying said annotated map on the same monitor, at a location spaced from at least a selected portion of the displayed x-ray image.
13. A method as in claim 1 including printing a film version of said x-ray image in digital form and of said annotated map, wherein said displaying comprises displaying said film version at a lightbox, with said annotated map spaced from a display of at least a selected portion of the displayed x-ray image.
14. A method as in claim 1 in which said x-ray image in digital form is a mammogram.
15. A method as in claim 14 including taking a film mammogram and generating said x-ray image in digital form therefrom.
16. A system comprising:
a source of a medical x-ray image in digital form;
a processor processing said x-ray image digitally to detect suspected abnormalities therein;
said processor creating as a result of said processing an annotated map showing both locations of suspected abnormalities and values related to a likelihood that the abnormalities are true abnormalities;
a display coupled with said processor to display both the x-ray image and said annotation map.
17. A system as in claim 14 in which said display comprises a first area displaying said x-ray image and a second area, spaced at least from a selected part of said first area and displaying said annotation map.
18. A system as in claim 16 in which said source of a medical x-ray image in digital form comprises a mammography imager.
19. A system as in claim 18 in which said mammography imager comprises a film mammograph and a digitizer converting film images therefrom into digital form.
20. A system as in claim 16 in which said processor creates an annotated map that uses a first notation to show suspected abnormalities having a first threshold of likelihood that they are true abnormalities.
21. A system as in claim 20 in which said processor creates an annotated map that further uses a second notation to show suspected abnormalities having a second threshold of likelihood that they are true abnormalities.
22. A system as in claim 21 in which said processor creates an annotated map that further uses a third notation to show suspected abnormalities having a third threshold of likelihood that they are true abnormalities.
