Automatic Learning of Image Features to Predict Disease
First Claim
1. A method for training a computer system for automatic detection of regions of interest in medical image data using a computer-based image processing device, comprising:
- receiving a plurality of patient records from an electronic medical records database, and for each of the received patient records;
identifying a text field and a medical image from within the patient record;
automatically segmenting the medical image to identify a structure of interest;
searching the text field for one or more keywords indicative of a particular abnormality associated with the structure of interest;
determining whether the text field indicates that the patient has the particular abnormality; and
adding the medical image to a grouping of medical images representing the particular abnormality when it is determined that the text field indicates that the patient has the particular abnormality and adding the medical image to a grouping of medical images representing the absence of the particular abnormality when it is determined that the text field does not indicate that the patient has the particular abnormality, andusing the grouping of medical images representing the particular abnormality and the grouping of medical images representing the absence of the particular abnormality to automatically train a computer system for the subsequent detection of the particular abnormality.

Abstract
A method for training a computer system for automatic detection of regions of interest includes receiving patient records. For each of the received patient records a text field and a medical image are identified from within the patient record and the medical image is automatically segmented to identify a structure of interest. The text field is searched for one or more keywords indicative of a particular abnormality associated with the structure of interest. The medical image is added to a grouping representing the particular abnormality when the text field indicates that the patient has the particular abnormality and the medical image is added to a grouping representing the absence of the particular abnormality when the text field does not indicate that the patient has the particular abnormality. The groupings of medical images are used to automatically train a computer system for the subsequent detection of the particular abnormality.

16. A computer system comprising:
-
a processor; and a program storage device readable by the computer system, embodying a program of instructions executable by the processor to perform method steps for training a computer system for automatic detection of regions of interest, the method comprising; receiving a plurality of patient records from an electronic medical records database, and for each of the received patient records; identifying a text field and a medical image from within the patient record; automatically segmenting the medical image to identify a structure of interest; determining whether the text field indicates that the patient has a particular abnormality associated with the structure of interest; and adding the medical image to a grouping of medical images representing the particular abnormality when it is determined that the text field indicates that the patient has the particular abnormality and adding the medical image to a grouping of medical images representing the absence of the particular abnormality when it is determined that the text field does not indicate that the patient has the particular abnormality, and using the grouping of medical images representing the particular abnormality and the grouping of medical images representing the absence of the particular abnormality to automatically train a computer system for the subsequent detection of the particular abnormality. - View Dependent Claims (17, 18, 19, 20)
