With a total of six patents to her name, she has developed innovative methods that enhance the detection and analysis of medical images, particularly in the context of lung abnormalities.
Latest Patents
Among her latest patents are two groundbreaking inventions: a method and system for the automated temporal subtraction of medical images, and a computerized detection system for lung nodules. The first patent focuses on obtaining three-dimensional images from CT scans, utilizing a gray-level thresholding technique to select sections containing anatomical features like the lungs. This method employs rotation correction and cross-correlation techniques for initial registration, followed by local matching for improved accuracy. The final output enhances the visibility of interval changes, such as tumor size alterations and newly developed pleural effusions.
The second patent presents a sophisticated approach for the computerized detection of lung abnormalities. This system involves generating difference images from standard and soft-tissue digital chest images, identifying candidate abnormalities, and extracting features to analyze and eliminate false positives. The logical OR operation of detected abnormalities from both images results in an impressive detection sensitivity of over 90%, with a minimal false positive rate.
