Abstract

A computer database for medical imaging stores and manipulates multimedia data from various sources and reduces misidentification of data. A unique identifier is generated and linked to each data object, preferably at the time the image is generated. A graphical representation of the identifier is incorporated into the image or text when displayed or printed. A detector may be used to read the representation, allowing the identifier to be read and identify the data.

Claims

1. A database management system for a database of multimedia data objects visually presentable to a user in hard copy form, wherein each of the data objects includes pixel values and has an associated unique identifier, comprising:

an encoder responsive to signals corresponding to the unique identifier associated with a data object for generating an array of pixel values corresponding to a bit map of a machine readable identifying indicia representative of the unique identifier;

an adder for adding the pixel values corresponding to a bit map of the machine readable identifying indicia to the pixel values of the data object to integrate the machine readable identifying indicia with the data object;

a hard copy generator for generating a hard copy of the data object and the integrated machine readable identifying indicia;

a detector device for generating signals indicative of the bit map of the integrated machine readable identifying indicia from the hard copy; and

a decoder responsive to the signals indicative of the bit map of the integrated machine readable identifying indicia.

2. The management system of claim 1, further comprising a converter for converting data objects into a format compatible with each of the other data objects.

3. The management system of claim 1, further comprising a memory for storing the data objects.

4. The management system of claim 3, wherein the memory provides the data object in response to the decoded integrated unique identifier.

5. The management system of claim 1, further comprising a communications link for electronically transmitting data objects to a remote location.

6. The management system of claim 1, further comprising an editor for selecting portions of a first data object and portions of a second data object to create a third data object comprising at least one of the selected portions.

7. The management system of claim 1, wherein the hard copy of the data object is comprised of film.

8. The management system of claim 1, wherein the hard copy of the data object is comprised of reflective paper.

9. The management system of claim 1, further comprising a scanner for scanning a hard copy of information and creating data objects based on the information.

10. The management system of claim 9, further comprising a converter connected to the scanner for converting data from the scanner into a format compatible with the formats of other data objects.

11. The management system of claim 1, wherein the associated unique identifier is based at least in part on information relating to the data object.

12. The management system of claim 1, wherein the data object includes analog data, and further comprising a digitizer for digitizing the analog data.

13. The management system of claim 1, further comprising:

a memory for storing each data object at an address; and

a directory for storing each unique identifier, wherein the directory links the unique identifier in the directory with the memory address of the corresponding data object.

14. The management system of claim 1, wherein the machine readable representation of the identifier includes a gray scale component.

15. A database management system for a database of multimedia data objects generated by at least one medical imaging device, wherein the data objects are visually presentable in hard copy form, include pixel values, and are associated with a unique identifier, comprising:

a computer, including;

an encoder responsive to signals representative of the unique identifier for generating pixel values corresponding to a bit map of machine readable indicia representative of the unique identifier;

an adder for adding the pixel values corresponding to the bit map of the machine readable encoder values to the pixel values of the data object to integrate the machine readable indicia with the data object; and

a decoder responsive to signals indicative of the bit map of the indicia for deriving the corresponding unique identifier from the machine readable indicia;

a hard copy generator for generating a hard copy representation of the data object and the machine readable indicia representative of the unique identifier;

a detector device for generating signals indicative of the bit map of the machine readable indicia in the hard copy representation; and

a scanner for generating additional data objects in the database from hard copy representations.

16. The management system of claim 15, wherein the unique identifier is assigned at approximately the same time the data object is generated.

17. The management system of claim 15, wherein the computer further comprises a memory for storing data objects.

18. The management system of claim 17, wherein the memory provides data objects in response to detected unique identifiers.

19. The management system of claim 15, wherein first and second unique identifiers relating to first and second data objects are related to facilitate correlation of the first and second data objects.

20. The management system of claim 15, wherein a first unique identifier is assigned to a pixel data component and a second unique identifier is assigned to a textual data component, wherein the first and second unique identifiers are related to facilitate correlation of the textual data component to the pixel data component.

21. The management system of claim 15, further comprising a communications link for electronically transmitting data objects to a remote location.

22. The management system of claim 15, further comprising an editor for selecting portions of the data objects to create a further data objects comprising at least one of the selected portions.

23. The management system of claim 15, wherein the hard copy of the information is comprised of film.

24. The management system of claim 15, wherein the hard copy of the information is comprised of reflective paper.

25. The management system of claim 15, further comprising a converter connected to the scanner for converting data from the scanner into a format compatible with other data objects in the database.

26. The management system of claim 15, wherein the unique identifier is assigned based at least in part on information relating to the corresponding data object.

27. The management system of claim 15, wherein a data object includes analog data, and further comprising a digitizer for digitizing the analog data.

28. The management system of claim 15, further comprising:

a memory for storing each data object at an address; and

a directory for storing a plurality of the unique identifiers, wherein the directory links each unique identifier in the directory with the memory address of the corresponding data object.

29. The management system of claim 15, wherein the bit map representative of the unique identifier includes a gray scale component.
