Abstract

A Radiology Healthcare Network provides high quality, timely medical interpretations of radiological images on a national (e.g., across the U.S.) and regional basis. The images can include images created by conventional x-ray technology, computed radiography, magnetic resonance imaging (MRI), computed tomography (CT), ultrasound imaging, nuclear medicine, and mammography equipment. The invention includes the acquisition of these images from health care facilities, the conversion of these images to digital format, the routing of these converted images, the interpretation of these routed images, and the routing of the interpretations back to the originating facility. The images are routed (e.g., on a variety of high-speed digital and analog telecommunication networks) to the appropriate interpretation resource by an administrative site on the Network based on one or more requirements associated with the radiological study. The interpretation can be performed on high-resolution workstations and/or on films produced by film printers. The invention can include quality control measures which assure high image and interpretation quality. The control and tracking of images by the administrative site results in the production of a complete, signed interpretive report in a timely manner.

Claims

1. A method for providing interpretation of radiological images, comprising:

coupling a data processing system of an administrative site to a wide area network;

coupling a plurality of acquiring sites to the wide area network for acquiring radiological images and for generating identifying information about a radiology study, the study including one or more of the images;

coupling a plurality of interpretation sites to the wide area network for gathering information about the interpretation sites and for communicating selected information between the interpretation sites and the administrative site;

receiving the identifying information about the study from one of the acquiring sites over the wide area network and through the data processing system;

utilizing the received identifying information to determine one or more study parameters from the received identifying information;

comparing the study parameters at the administrative site with information about the interpretation sites to select an optimum interpretation site to interpret the study from the available interpretation sites and from current information gathered over the wide area network;

routing the study onto the wide area network, under the control of the administrative site, to the selected interpretation site;

receiving report information at the administrative site about an interpretation of the study from the selected interpretation site over the wide area network; and

routing the study interpretation, under the control of the administrative site, to the acquiring site from which the study identifying information about the radiology study was received.

2. The method of claim 1 wherein the step of utilizing the received identifying information to determine one or more study parameters includes the step of determining a modality of the study.

3. The method of claim 2 wherein the step of determining a modality of the study includes the step of determining whether the study includes the use of computer assisted tomography.

4. The method of claim 2 wherein the step of determining a modality of the study includes the step of determining whether the study includes the use of x-ray imaging.

5. The method of claim 2 wherein the step of determining a modality of the study includes the step of determining whether the study includes the use of magnetic resonance imaging.

6. The method of claim 2 wherein the step of determining a modality of the study includes the step of determining whether the study includes the use of nuclear medicine.

7. The method of claim 2 wherein the step of determining a modality of the study includes the step of determining whether the study includes the use of ultrasound imaging.

8. The method of claim 2 wherein the step of determining a modality of the study includes the step of determining whether the study includes the use of computed radiography.

9. The method of claim 1 wherein the step of utilizing the received identifying information to determine one or more study parameters includes the step of determining a suspect pathology of the study.

10. The method of claim 1 wherein the step of utilizing the received identifying information to determine one or more study parameters includes the step of determining a geographic location of the acquiring site.

11. The method of claim 1 wherein the step of utilizing the received identifying information to determine one or more study parameters includes the step of determining demographic information about a patient which is a subject of the study.

12. The method of claim 1 wherein the step of utilizing the received identifying information to determine one or more study parameters includes the step of determining information about an anatomy of a patient which is a subject of the study.

13. The method of claim 1, further comprising the step of utilizing the administrative site for monitoring a progress of the study interpretation by the selected interpretation site.

14. The method of claim 13 wherein the step of utilizing the administrative site for monitoring comprises the further step of monitoring the selected interpretation site for timeliness.

15. The method of claim 13 wherein the step of utilizing the administrative site for monitoring comprises the further step of monitoring the selected interpretation site for requests for more patient information.

16. The method of claim 1, wherein the acquiring site comprises a hospital.

17. The method of claim 1, wherein the acquiring site comprises a diagnostic imaging center.

18. The method of claim 1, wherein the acquiring site comprises a mobile imaging facility.

19. The method of claim 1 wherein the step of comparing the study parameters further comprises the step of selecting an optimum interpretation site based upon matching the study parameters with availability of specialty and subspecialty resources at the interpretation site to provide medical coverage for one of the acquiring sites.

20. The method of claim 19 wherein the step of comparing the study parameters further comprises the step of monitoring a backlog at the interpretation site.

21. The method of claim 1 wherein the step of comparing the study parameters further comprises the step of selecting an optimum interpretation site based upon required turnaround time of the interpretation.

22. The method of claim 14 wherein the step of monitoring the timeliness comprises the further step of determining whether the interpretation site has completed the study interpretation within a predetermined amount of time.

23. The method of claim 1, further comprising the step of implementing quality control measures at the administrative site for image and interpretation quality.
