Abstract

A method for providing centralized anatomic pathology services. A plurality of regional pathology laboratories is provided, each laboratory servicing a defined geographic region. A master storage (e.g., database) of pathology information is maintained, the storage being accessible by pathologists associated with any regional laboratory via a communications link. Tissue samples requiring pathology processing are collected from a medical entity located in a first geographic region by a regional pathology laboratory. The tissue is processed, and a tissue slide is created. A digital, diagnostic quality image of the tissue slide is created and stored in the master storage. A pathologist, who may be remotely located with respect to the first geographic region, is provided with access to the stored diagnostic image via the communications link, to enable diagnosis by the pathologist without physical possession of the slide. The digital, diagnostic quality image may be compressed before it is stored in the master storage. The diagnosis may be a primary or a secondary diagnosis. In the case of a secondary or supplemental diagnosis, the pathologist is provided with access to any prior analysis and annotations, stored in the master storage, relating to the diagnostic image. A system for implementing the method is also disclosed.

7. The method of claim 5, wherein the analysis and annotations includes an annotated overlay for the digital image.

8. The method of claim 1, wherein the pathologist is remotely located with respect to the first geographic region.

9. The method of claim 1, wherein the diagnosis is a primary diagnosis.

10. The method of claim 1, wherein the diagnosis is a secondary diagnosis.

11. The method of claim 10, further comprising providing access to prior analysis and annotations, stored in the memory, relating to the diagnostic image to the pathologist to enable the secondary diagnosis by the pathologist.

12. The method of claim 1, wherein the memory storing pathology information includes diagnostic treatment information.

13. The method of claim 12, further comprising providing diagnostic treatment information relating to the diagnosis to an authorized user.

14. The method of claim 1, wherein the geographic region serviced by the regional laboratory includes areas within a radius of approximately one-hundred miles from the regional laboratory.

15. The method of claim 1, wherein the step of creating a digital, diagnostic quality image of the tissue slide includes combining optical magnification and non-empty digital magnification.

16. The method of claim 1, wherein the step creating a digital, diagnostic quality image of the tissue slide includes capturing multiple images of the tissue slide, each of which is in focus for a particular depth of field range.

17. The method of claim 16, wherein the step of creating a digital, diagnostic quality image of the tissue slide further includes digitally combining the multiple images of the tissue slide to create a single image that is in focus at every depth of field range.

18. The method of claim 1, further comprising providing simultaneous access to the diagnostic quality, digital image to two or more pathologists via the communications link to enable simultaneous diagnosis by the pathologists without physical possession of the slide.

19. A system for providing centralized anatomic pathology services comprising:

a scanning device for creating a digital, diagnostic quality image of a tissue slide;

a database configured to store pathology information, including the digital, diagnostic quality image;

a processor configured to compress the digital, diagnostic quality image prior to storage in the database and provide access to pathology information, including the image, to an authorized user to enable diagnosis by the user without physical possession of the slide; and

a communications link connecting a plurality of regional pathology laboratories and other authorized users to the server computer, where each laboratory services a defined geographic region.

20. The system of claim 19, wherein the pathology information stored in the database further includes diagnostic treatment information.

21. The system of claim 19, wherein the processor is further configured to provide diagnostic treatment information relating to the diagnosis to an authorized user.
