Abstract

A system for reviewing a prior medical image and a related prior medical report, including: a plurality of measurement tools configured to: receive an input medical image and information regarding a medical finding; analyze the input medical image to determine a measurement relating to the medical finding; and output the measurement relating to the medical finding; a report analyzer configured to: receive the prior medical report; analyze the prior medical report to extract first information regarding a first medical finding described in the medical report; select a first measurement tool of the plurality of measurement tools to analyze the prior medical image based upon the first extracted information; and output the first extracted information to the first measurement tool, wherein the first measurement tool analyzes the prior medical image to produce a first updated measurement of the first medical finding and the first measurement tool analyzes a new medical image associated with the prior medical image to produce a new first measurement of the first medical finding; a report generator configured to receive the new first measurement and to produce a new report based upon the new first measurement.

First claim

The invention claimed is:

1. A system for reviewing a prior medical image and a related prior medical report, comprising:
a plurality of measurement tools including at least a size measurement tool and an opacity measurement tool, the plurality of measurement tools configured to:
receive the prior medical image and information regarding a medical finding;
analyze the prior medical image to determine a size measurement relating to the medical finding using the size measurement tool;
analyze the prior medical image to determine an opacity measurement relating to the medical finding using the opacity measurement tool; and
output the measurement relating to the medical finding;

a report analyzer configured to:
receive the prior radiology report;
analyze the prior radiology report to extract first information regarding a first medical finding described in the prior radiology report;
select one of the size and opacity measurement tools to analyze the prior medical image based upon the first extracted information; and
output the first extracted information to the first measurement tool, wherein the selected measurement tool remeasures the prior medical image to produce a first updated measurement of the first medical finding and the same selected measurement tool measures a new medical image associated with the prior medical image to produce a new first measurement of the first medical finding;

a report generator configured to:
receive the new first measurement of the first medical finding and the first updated measurement of the first medical finding; and
produce a new radiology report including inserting new report text containing the first updated measurement of the first medical finding and the new first measurement of the first medical finding into the new radiology report; and

a graphical user interface configured to display the new radiology report including the inserted new report text containing the first updated measurement of the first medical finding and the new first measurement of the first medical finding, and further configured to display the prior radiology report, the prior medical image, and the new medical image.

2. The system of claim 1 , wherein the report analyzer includes a natural language processing engine and wherein the report generator includes a natural language processing engine.

3. The system of claim 1 , wherein the report generator further receives style information from the report analyzer and the new radiology report has the same style as the prior radiology report.

4. The system of claim 1 , wherein the report analyzer is further configured to:
analyze the prior radiology report to extract second information regarding a first medical finding described in the prior radiology report;
select the remaining measurement tool of the size and opacity measurement tools to analyze the prior medical image based upon the second extracted information; and
output the second extracted information to the second measurement tool,
wherein the selected remaining measurement tool analyzes the prior medical image to produce an updated second measurement of the first medical finding and the selected remaining measurement tool analyzes a new medical image associated with the prior medical image to produce a new second measurement of the first medical finding.

5. The system of claim 1 , wherein the report analyzer is further configured to:
analyze the prior radiology report to extract second information regarding a second medical finding described in the prior radiology report;
select the remaining measurement tool of the size and replacement measurement tools to use to analyze the prior medical image based upon the extracted second information; and
output the second extracted information to the second measurement tool,
wherein the selected remaining measurement tool analyzes the prior medical image to produce an updated second measurement of the second medical finding and the selected remaining measurement tool analyzes a new medical image associated with the prior medical image to produce a new first measurement of the second medical finding.

6. The system of claim 1 , wherein the first measurement tool uses one of machine learning and image processing to analyze the medical image.

7. The system of claim 1 , wherein the graphical user interface is further configured to display condition progression information.

8. The system of claim 7 , wherein the condition progression information comprises disease progression information.

9. The system of claim 1 , wherein the size measurement tool facilitates interaction with the prior medical image.

10. The system of claim 1 , wherein the size measurement tool is a CAD tool and the system is a radiology system.

11. A method for producing a new radiology report on a follow-up examination including automatically reviewing a prior medical image and a related prior radiology report, the method comprising:
receiving, by a report analyzer, the prior radiology report;
analyzing, by the report analyzer, the prior radiology report to extract first information regarding a first medical finding described in the prior radiology report;
using a size measurement tool to analyze the prior medical image based upon the first extracted information;
outputting the first extracted information to the size measurement tool;
remeasuring, by the size measurement tool, the prior medical image to produce a first updated measurement of the first medical finding;
measuring, by the size measurement tool, a new medical image associated with the prior medical image to produce a new first measurement of the first medical finding;
outputting, by the size measurement tool, both the new first measurement of the first medical finding and the first updated measurement of the first medical finding to a report generator; and
producing, by the report generator, the new radiology report including inserting new report text containing the first updated measurement of the first medical finding and the new first measurement of the first medical finding into the new radiology report; and
displaying, by a graphical user interface, the new radiology report including the inserted new report text containing the first updated measurement of the first medical finding and the new first measurement of the first medical finding, and further displaying the prior radiology report, the prior medical image, and the new medical image.

12. The method of claim 11 , wherein the report analyzer is a natural language processing engine and wherein the report generator is a natural language processing engine.

13. The method of claim 11 , wherein the report generator further receives style information from the report analyzer and the new radiology report has the same style as the prior radiology report.

14. The method of claim 11 , further comprising,
analyzing, by the report analyzer, the prior radiology report to extract second information regarding a first medical finding described in the prior radiology report;
using an opacity measurement tool to analyze the prior medical image based upon the second extracted information;
outputting the second extracted information to the opacity measurement tool;
analyzing, by the opacity measurement tool, the prior medical image to produce an updated second measurement of the first medical finding; and
analyzing, by the second measurement, a new medical image associated with the prior medical image to produce a new second measurement of the first medical finding.

15. The method of claim 11 , further comprising,
analyzing, by the size measurement to
