Abstract—Objective To evaluate the influence of monochrome one pare observer performance using the same brand of
LCDs with different resolutions on the detection performance of medical monochrome LCDs with different resolutions for the
pulmonary nodules. Materials and Methods 93 chest images were detection of pulmonary nodules. Full consideration was given
