| Abstract(in English) | In picture archiving and communications systems(PACS) or digital archiving systems, the information on the posteroanterior(PA) and lateral views for chest radiographs is often not recorded or is recorded incorrectly. However, it is necessary to identify the PA or lateral view correctly for quantitative analysis of chest images for computer-aided diagnosis. Our purpose in this study was to develop a computerized method for correctly identifying either PA or lateral views of chest radiographs. Our approach is to examine the similarity of a chest image with templates that represent the average chest images of the PA or lateral view. By use of a template matching technique, correlation values were obtained for determining whether a chest image is either a PA or a lateral view. Either PA or lateral view of all 1357 cases tested were identified correctly and automatically by examining the correlation values of a chest image with a number of templates in two steps. |
