Computer-aided diagnosis method and system
First Claim
1. A method comprising:
- processing a medical x-ray image in digital form to detect suspected abnormalities;
creating an annotated map of suspected abnormalities detected in said processing;
wherein said map shows both locations of suspected abnormalities and values related to confidence levels that suspected abnormalities are true abnormalities;
said confidence levels being user selectable; and
displaying both the x-ray image and the annotation map to a user.

Abstract
A computer-aided diagnostic (CAD) method and system provide image annotation information that can include an assessment of the probability, likelihood or predictive value of the CAD-detected suspected abnormalities as an additional aid to the radiologist. More specifically, probability values, in numerical form and/or analog form, are added to the locational markers of the CAD-detected suspected abnormalities. The task of a physician using a CAD system is believed to be made easier by displaying two different markers representing different probability thresholds. An additional threshold can be used to display “extra view markers” as an additional aid or guide to the radiologic technician to take extra views of a patient before the patient is released or discharged. A control device is added to allow the user to select and vary the probability threshold for the display of locational markers.

16. A system comprising:
-
a source of a medical x-ray image in digital form;
a processor processing said x-ray image digitally to detect suspected abnormalities therein;
said processor creating as a result of said processing an annotated map showing both locations of suspected abnormalities and values related to a likelihood that the abnormalities are true abnormalities;
a display coupled with said processor to display both the x-ray image and said annotation map. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
