window of ROI, image analysis, lung segmentation, active shape model, asymmetry detection
The concept - window of lung fields - is introduced in this paper. Definition and automatic calculation methods are also included. Using this concept, four applications are discussed: initial parameters setting of Active Shape Model (ASM) algorithm, a widely used algorithm in medical image analysis; auto focusing, which can be used in radiographic examination; asymmetry detection of lung fields and image compressing. All these applications are nice and easy provided that windowing technique is implemented, especially the automatic segmentation of lung fields: experiment results show that in most cases, only a few iteration steps are needed to find contours of lung fields. Other applications are also discussed and analyzed.
