Relationship Analysis Between Cephalometric Radiograph Shape and Swallowing Ability Using SOM² and CCA-SOM

Abstract

In this paper, we propose a method of a relationship analysis between cephalometric radiograph shape data and swallowing ability data. In order to acquire new knowledge of the relationship, the shape should be represented without missing features. In addition, a method of the relationship analysis between two data sets which are observed by different ways, an X-ray image and swallowing ability tests. Quantization and correspondence of points by SOM² are employed for shape representation. A common map of CCA-SOM are employed for the relationship analysis method. The propose method provides relationships between cephalometric radiograph shape and swallowing ability.
