With a total of 15 patents to his name, MacMahon has developed innovative methods and systems that enhance the accuracy and efficiency of medical diagnoses.
Latest Patents
Among his latest patents is an automated method and system for the evaluation of disease and registration accuracy in the subtraction of temporally sequential medical images. This invention involves an apparatus, method, and computer program product designed for performing computer-aided diagnosis on temporal subtraction images of objects. The process identifies a mode of a gray-level histogram and establishes a gray-level threshold at a predefined fraction of this modal value. Pixels with gray levels below this threshold within lung regions remain 'on,' while others are set to zero. This method imposes area and circularity requirements to eliminate false-positive regions, allowing for the presentation of pathologic changes as outlines in the subtraction image or highlighted regions in the original radiographic image.
Another notable patent focuses on a method, system, and computer-readable medium for the two-dimensional and three-dimensional detection of lesions in computed tomography scans. This invention automates the detection of lung nodules in CT image scans by generating two-dimensional segmented lung images and combining them into three-dimensional segmented lung volume images. It identifies structures that meet a volume criterion, derives features from lung nodule candidates, and detects lung nodules by analyzing these features to eliminate false-positive candidates.
