In recent years, many kinds of displays and recording systems for X-ray medical images have been used. In this paper, the sharpness of various medical imaging systems are analyzed and compared, such as the wet type and dry type photo printers using a silver halide material, high accurate monochrome CRT and LCD monitors, and the exclusive film and glossy paper by medical inkjet printer. The Gans’ method is modified to calculate the MTF with accuracy. It was well correlated between the MTF and observer rating value. From here, we consider the proposed method is effective.
