System and method for automatically detecting pulmonary nodules in medical images

摘要

A system and method for automatically segmenting a CT image of a patient's lung. The method includes segmenting a CT image to obtain one or more lung field regions and generating a mask region including a high signal region corresponding to an anatomy in the lung field region. Thresholding the region with signal strength, calculating a Euclidean distance map of the mask region, performing watershed segmentation of the Euclidean distance map to generate one or more subregions, respectively Identifying a seed point for each sub-region, expanding a candidate region from the seed point of each sub-region, and determining one or more candidate regions for pulmonary nodules based on one or more geometric features of the candidate region Classifying as: [Selection] Figure 1
