CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) PHANTOM FOR COMPUTED TOMOGRAPHY (CT) AND METHODS OF USING THE SAME

摘要

An imaging system (10)analyzes airways of a patient. The system (10) includes a hardware phantom (50) including tubes (54) representative of airways. The tubes (54) include different lumen sizes and/or wall thicknesses. The system further includes an imaging scanner (12) for scanning a region of interest (ROI), including the airways, and the hardware phantom (50) to create raw image data. At least one processor (32) is programmed to at least one of: (1) correct measurements of walls of the airways based on measurements of lumen size and/or wall thickness of the tubes (54) and known lumen size and/or wall thickness of the tubes (54); and (2) generate an image of the ROI in which color and/or opacity of the airways are based on a comparison of images or maps of the tubes (54) and images or maps of the airways. A corresponding method is also provided.
