This invention describes a system that automatically processes medical images, specifically comparing images taken before and after a contrast agent is injected into a patient. It uses rules, which a doctor can customize or create, to identify and highlight areas of interest, like lesions, in different colors. Once taught with sample images, the system applies these specific rules for that doctor to all subsequent images, saving time and effort.
Why it matters: Filed before the rise of advanced machine learning. The claims describe a rules-based system, but today, AI could learn and apply doctor preferences for contrast image analysis with far greater sophistication and accuracy.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
