Design of Synthetic 3-D Pulmonary Phantoms Using 2-D Graphical User Interface

Analysis of pulmonary artery or vein tree has utmost importance in the study and clinical diagnosis of Chronic Obstructive Pulmonary Diseases (COPD). Due to difficulty in acquiring real life patient data and highly complex structure of artery/vein tree, design of imitated/approximate digital pulmonary phantoms for experimental purposes is an active research area. In this work, we discuss theory and methods of designing 3-D mathematical phantoms based on real pulmonary data using a custom made Graphical User Interface (GUI). These approximate phantoms are made using 3-D spheres as the basic unit which are placed in 3-D space using cubic Bezier curves. Results and design steps are explained using appropriate 3-D rendering of digital phantoms developed by our GUI.
