creating an image database from a collection of images pertaining to a particular subject matter, said image database residing on a mass storage device operatively associated with a computer and including icons as display objects representing diagnoses with associated symptoms;

creating a knowledge database with other data related to the particular subject matter, wherein said knowledge database includes a plurality of findings-diagnosis links representing relationships between findings and diagnoses and is cross-referenced to said image database, for the purpose of assisting in the diagnostic process;

using the computer, including a user interface having a display and storage device accessibly by said computer and containing said image database and knowledge database, collecting from a user, through a sympticon interface adapted to a particular subject matter, a plurality of symptoms of a patient requiring diagnosis;

operating a diagnostic engine on the computer, in response to the collected symptoms, and using findings-diagnosis links, where the computer automatically generates, from a plurality of possible diagnoses included within the knowledge database, a subset including a plurality of possible diagnoses consistent with the symptoms collected from the user; and

using the subset of possible diagnoses, automatically reorganizing an information space of said image database for concurrent presentation on said sympticon interface of a plurality of images related to the plurality of possible diagnoses for user review, wherein said sympticon interface includes a display of icons representing a subset of possible diagnoses in conjunction with at least some symptoms for user review via the interface and where a plurality of symptoms are concurrently presented on the display of the sympticon interface such that a visual comparison may be made of the possible diagnoses to consider similarities and differences between symptoms for each of the possible diagnoses.

2. The method according to claim 1, further comprising adding a symptom or finding, including:

selection, on the sympticon interface, of an additional symptom or finding; and

in response to the additional symptom or finding, updating the subset of possible diagnoses to create a new subset of diagnoses and automatically reorganizing the information space of said image database for concurrent presentation on said sympticon interface of a new set of images on the sympticon interface related to the plurality of possible diagnoses consistent with all current symptoms and findings.

3. The method according to claim 2, further comprising removing a symptom or finding, including:

selection, on the sympticon interface, of a symptom or finding to be removed, and as a result creating an updated subset of symptoms or findings that eliminates the removed symptom or finding; and

in response to the removed symptom or finding, updating the subset of possible diagnoses to create an updated subset of diagnoses and automatically reorganizing the information space of said image database for concurrent presentation on said sympticon interface of a further set of images on the sympticon interface related to the plurality of possible diagnoses consistent with the updated symptoms and findings.

4. The method according to claim 1, further comprising:

representing user-entered symptoms or findings on said sympticon interface using a first display format; and

representing other symptoms associated with each possible diagnosis displayed on said sympticon interface in a different display format such that a user will visually differentiate the user-entered symptoms or findings from the other symptoms for each diagnosis displayed.

5. The method according to claim 1, further comprising initiating a dynamic interaction for at least one sympticon displayed on the sympticon interface.

6. The method according to claim 5, wherein the dynamic interaction is selected from the group consisting of:

adding the symptom or finding represented by the at least one sympticon;

removing the symptom or finding represented by the at least one sympticon;

presenting additional descriptive information for the at least one sympticon; and

presenting images representative of the symptom or finding.

7. The method according to claim 1, wherein operating a diagnostic engine on the computer includes comparing, with a processor in the computer, the finding-diagnosis links in said knowledgebase with respect to each of the diagnoses to determine those diagnoses associated with said symptoms, and creating the subset of possible diagnoses from those diagnoses.

8. The method according to claim 1, further including at least one test icon on the sympticon interface, to prompt the user to consider a test that rules a particular diagnosis in or out.

9. The method according to claim 1, further including at least one geographic icon on the sympticon interface, to indicate a geographic region with which the diagnosis has a known association.

10. The method according to claim 1, wherein a plurality of sympticons are presented as a diagnostic image stack.

11. A system to aid a user in a diagnostic process, comprising:

a computer system, said computer system including a user interface having a display and at least one storage device for storing an image database, accessible by said computer system, where said image database includes a plurality of sympticons;

a knowledge database, accessible by said computer system, cross-referenced to said image database, for the purpose of assisting in the diagnostic process, said knowledge database including a plurality of findings-diagnosis links representing relationships between findings and diagnoses;

a sympticon interface operatively associated with and controlled by said computer system to solicit, from the user, a plurality of descriptive characteristics of a sample requiring diagnosis, said sympticon interface including at least one descriptive characteristic of a sample requiring diagnosis where the characteristic is represented both as an icon and text;

a diagnostic engine operating in said computer system, responsive to said descriptive characteristics, including the characteristic from said characterization device, wherein said characteristics of the sample are employed by said engine to automatically identify, using the findings-diagnosis links, a subset including a plurality of possible diagnoses that are consistent with the characteristics; and

using the subset of diagnoses, said computer system automatically reorganizing an information space of said image database for concurrent presentation of the possible diagnoses using said sympticon interface, wherein said sympticon interface includes a display of icons representing the subset of possible diagnoses in conjunction with at least some symptoms for user review via the interface and where a plurality of symptoms are concurrently presented on the display of the sympticon interface such that a visual comparison may be made of the possible diagnoses to consider similarities and differences between symptoms for each of the possible diagnoses.

12. The system according to claim 11, further comprising adding a symptom or finding using the sympticon interface, including:

on the sympticon interface selecting an additional symptom or finding; and

updating the subset of possible diagnoses to create a new subset of diagnoses in response to the additional symptom or finding, and automatically reorganizing the information space of said image database for concurrent presentation on said sympticon interface of a new set of images on the sympticon interface related to the plurality of possible diagnoses consistent with all current symptoms and findings.

13. The system according to claim 12, further comprising removing a symptom or finding using the sympticon interface, including:

on the sympticon interface selecting a symptom or finding to be removed, and as a result creating an updated subset of symptoms or findings that eliminates the removed symptom or finding; and

updating the subset of possible diagnoses to create an updated subset of diagnoses in response to the removed symptom or finding, and automatically reorganizing the information space of said image database for concurrent presentation on said sympticon interface of a further set of images on the sympticon interface related to the plurality of possible diagnoses consistent with the updated symptoms and findings.

14. The system according to claim 11, further comprising:

presenting user-entered symptoms or findings on said sympticon interface using a first display format; and

presenting other symptoms associated with each possible diagnosis displayed on said sympticon interface in a different display format such that a user will visually differentiate the user-entered symptoms or findings from the other symptoms for each diagnosis displayed.

15. The system according to claim 11, wherein said sympticon interface further enables a user to initiate a dynamic interaction with at least one sympticon displayed on the sympticon interface.

16. The system according to claim 15, wherein the dynamic interaction is selected from the group consisting of:

adding the symptom or finding represented by the at least one sympticon;

removing the symptom or finding represented by the at least one sympticon;

presenting additional descriptive information for the at least one sympticon; and

presenting images representative of the symptom or finding.

17. The system of claim 11, wherein a plurality of sympticons are presented as a diagnostic image stack.

18. A computer system for reducing diagnostic uncertainty using cross-referenced knowledge and image databases stored in an accessible storage device, comprising:
