Enlarged cardiothoracic ratio (CTR) in chest X-ray is related to cardiac dysfunction. We developed a software program that provided an automated measurement of CTR from chest X-ray image files. With high accuracy, CTR was calculated from chest X-ray images taken in outpatient clinics. It may be helpful for physicians to reduce routine work and to detect latent heart disease.
