Abstract

The malignancy rate of GGN is different according to the presence and the size of a solid component. Thus, it is important to differentiate part-solid GGN with a variable sized solid component from pure GGN. In this paper, we propose a method of classifying the GGNs according to presence or size of solid component using multiple 2.5- dimensional deep CNNs. First, to consider not only intensity but also texture, and shape information, we propose an enhanced input image using image augmentation and removing background. Second, we proposed GGN-Net which can classify GGNs into three classes using multiple input images in chest CT images. Finally, we comparatively evaluate the classification performance according to different type of input images. In experiments, the accuracy of the proposed method using multiple input images was the highest at 82.76% and it was 10.35%, 13.79%, and 6.90% higher than that of using three single input image such as intensity-based, texture- and shape-enhanced input images, respectively.
