概要

• 論文の詳細を見る

• A new imaging system for chest radiography which has higher sensitivity in the mediastinum area than in the lung area has been developed. Through use of this new system for routine clinical examinations, the mediastinum area and lung areas are simultaneously displayed with a single exposure in optimal contrast. We investigated the fundamental physical properties of this system by comparing such items as its relative speed, modulation transfer functions (MTFs), density dependence on X-ray spectra, and low-contrast signal detections, with those of the conventional standard screen-film system.
