Abstract

A system is disclosed for providing pathology diagnostic opinions to physicians at sites remote from where the consulting pathologist is physically located. The system includes a robotically controlled microscope at the remote site equipped with a video camera means for collecting video signals from the microscope. The system also uses a bidirectional communication means to link the microscope with a pathologist workstation. The workstation includes a monitor for viewing images received from the video camera means and control means for generating control signals which are sent over the bidirectional communication means to thereby remotely control the microscope. Preferably, the system also includes means for electronically storing the X, Y, and Z microscope stage coordinates for particular points of the specimen viewed by the pathologist together with means for storing electronically and reproducing photographically the images viewed.

Claims

1. A telepathology diagnostic system which allows a pathologist located at a diagnostic center to render pathology diagnostic opinions in connection with specimens located at a site which is remote from the diagnostic center, which system comprises:

a microscope located at the remote site including robotic means for adjusting the relative position of a specimen to the lens, the magnification of the specimen, and the focus of the specimen;

video camera means for collecting video signals from the microscope;

bidirectional communication means for communicating signals between the remote site and the diagnostic center;

a pathologist workstation located at the diagnostic center and comprising a monitor for viewing the video signals collected by the video camera means which signals are sent over the bidirectional communication means, and further comprising microscope control means by which the pathologist generates control signals which are sent over the bidirectional communication means to the robotic means of the microscope so that the pathologist can thereby remotely adjust the relative position of the specimen to the lens, the magnification of the specimen, and the focus of the specimen; and

means for determining and storing coordinates corresponding to the relative position of the specimen to the lens of selected microscopic fields of interest;

whereby the system provides the pathologist located at the diagnostic center with the ability to remotely adjust the relative position of the specimen to the lens, the magnification of the specimen, and the focus of the specimen to thereby make observations of various microscopic fields on the specimen necessary for rendering a pathology diagnostic opinion, and the ability to store the coordinates of said selected microscopic fields of interest for later reference.

2. The system of claim 1 wherein the coordinates are determined and stored in the form of X, Y and Z coordinates.

3. The system of claim 2 wherein the means for determining and storing the coordinates of selected microscopic fields includes means associated with the microscope for generating location signals in the form of X, Y and Z coordinates of microscopic fields being viewed, which location signals are continuously sent over the bidirectional communication means to the pathologist workstation and means operable by the pathologist for selecting various microscopic fields as microscopic fields of interest for which the X, Y and Z coordinates are stored.

4. The system of claim 3 wherein the means for selecting various microscopic fields as microscopic fields of interest comprise a series of buttons, each corresponding to a selected field.

5. The system of claim 4 wherein the buttons are each numbered.

6. The system of claim 4 wherein each of the buttons are configured so that, when pressed a first time for a given sample, a microscopic field of interest is selected, and so that, when pressed a subsequent time, the specimen is returned to that microscopic field of interest.

7. The system of claim 4 wherein each of the buttons light up a field has been selected with that button.

8. The system of claim 3 further comprising means for generating control signals which cause the specimen to be returned to the microscopic fields of interest previously selected by the pathologist.

9. The system of claim 8 further comprising means for generating magnification return control signals which cause the magnification of the microscope to be returned to that which was being used when said microscopic fields of interest were selected.

10. The system of claim 1 wherein the pathologist workstation further comprises means for electronically storing video images of the microscopic fields of interest.

11. The system of claim 10 further comprising means for reproducing said video images.

12. A telepathology diagnostic system which allows a pathologist located at a diagnostic center to render pathology diagnostic opinions in connection with specimens located at a site which is remote from the diagnostic center, which system comprises:

a microscope located at the remote site including robotic means for adjusting the relative position of a specimen to the lens, the magnification of the specimen, and the focus of the specimen;

video camera means for collecting video signals from the microscope;

bidirectional communication means for communicating signals between the remote site and the diagnostic center;

a pathologist workstation located at the diagnostic center and comprising a monitor for viewing the video signals collected by the video camera means which signals are sent over the bidirectional communication means, and further comprising microscope control means by which the pathologist generates control signals which are sent over the bidirectional communication means to the robotic means of the microscope so that the pathologist can thereby remotely adjust the relative position of the specimen to the lens, the magnification of the specimen, and the focus of the specimen to thereby observe microscopic fields of interest; and

means for storing video images of selected microscopic fields of interest;

whereby the system provides the pathologist located at the diagnostic center with the ability to remotely adjust the relative position of the specimen to the lens, the magnification of the specimen, and the focus of the specimen to thereby make observations of various microscopic fields on the specimen necessary for rendering a pathology diagnostic opinion, and the ability to select microscopic fields of interest and have the video image of said selected microscopic fields of interest stored.

13. The system of claim 12 further comprising means for reproducing said video images.

14. The system of claim 13 further comprising means for storing a video image of said selected microscopic fields of interest.

15. The system of claim 12 further comprising means for photographically reproducing said video images.

16. A telepathology diagnostic system which allows a pathologist located at a diagnostic center to render pathology diagnostic opinions in connection with specimens located at a site which is remote from the diagnostic center, which system comprises:

a microscope located at the remote site including robotic means for adjusting the relative position of a specimen to the lens, the magnification of the specimen, and the focus of the specimen, and means for generating locations signals corresponding to the relative location of the specimen to the lens;

video camera means for collecting video signals from the microscope;

bidirectional communication means for communicating signals between the remote site and the diagnostic center;

a pathologist workstation located at the diagnostic center and comprising a monitor for viewing the video signals collected by the video camera means which signals are sent over the bidirectional communication means, and further comprising microscope control means by which the pathologist generates control signals which are sent over the bidirectional communication means to the robotic means of the microscope so that the pathologist can thereby remotely adjust the relative position of the specimen to the lens, the magnification of the specimen, and the focus of the specimen;

whereby the system provides the pathologist located at the diagnostic center with the ability to remotely adjust the relative position of the specimen to the lens, the magnification of the specimen, and the focus of the specimen to thereby make observations of various microscopic fields on the specimen necessary for rendering a pathology diagnostic opinion, and the ability to store the coordinates of said selected microscopic fields of interest for later reference.
