Abstract (in Japanese) (See Japanese page) 
(in English) High resolution medical imaging modalities, such as MRI, CT and so on, generate more than several hundreds CT images per person. This increase in the amount of image data is an important problem to consider. For that reason, Computer Aided Diagnosis (CAD) systems have been developed. We developed a positional classification method which applies training CT images to PCA, generates eigenspace and projects test CT images on the space. We are able to apply automatically classified results to a corresponding CAD system. The purpose of this research is to develop as automatic positional classification of body parts. In this report, we describe this using an appearance-based classification method.As the results, we could estimate about 82% mean accuracy rate.
