PULMONARY NODULE DETECTION USING CARTWHEEL PROJECTION ANALYSIS

摘要

A method for automatic detection of lung nodules in high-resolution multi-slice CT images by using cartwheel projection analysis is disclosed. The projection analysis employs weighted area curves obtained from a series of 2-dimensional cutting planes (201) rotated around a defined axis (202) in the volume of interest. Nodules are detected if the shape analysis of the weighted area curves meets a set of test-criteria (313, 314).
