Reconstructor and contrastor for medical anomaly detection

A system for diagnosing a patient condition, the system including:

• a medical imaging device for generating an anatomical image;
• an image patch extractor to extract portions of an anatomical image and partially masking the portions to generate partially masked image patches;
• a reconstructor to reconstruct the anatomical image by reconstructing the partially masked image patches of the anatomical image to be a healthy representation of the portions;
• an image merging module to merge the healthy representations into the original image to generate a reconstructed image;
• a contrastor to contrast the anatomical image with the reconstructed image to generate an anomaly map indicating locations of difference between the anatomical image and the reconstructed image;
• an anomaly tagging device to tag the locations of difference as anomalies corresponding to anatomical abnormalities in the anatomical image;
• and
• a diagnosis system to automatically administer a medication is response to a tag corresponding to the anatomical abnormality.
