The aim of our study was to develop a phantom of lung adenocarcinoma for use in a comparative evaluation of image quality among various chest X-ray systems. In this study, we developed type A, B, and C phantoms of lung adenocarcinoma according to Noguchi's classification. The shape of lung adenocarcinoma was assumed to be spherical with a different density in the core. The shapes of the phantoms were obtained by calculating equivalent thickness to X-ray transmission, leading to the same shadow as the sphere in order to perform practical visual evaluation using a chest lung phantom to which the phantoms were attached. The phantoms were tough water phantoms made by Kyoto Kagaku Co., Ltd. The performance of the phantoms was validated for chest radiographs of the phantoms attached to the surface of the chest lung phantom. The results of visual evaluation of tumor detectability by 13 radiologists and technicians showed generally good agreement with previous clinical data.
