| Research Abstract |
In this study, for the reduction of patient dose in radiologicexaminations, we investigated a relationship between degradation of diagnostic accuracydue to the increase of image noise and the reduction of exposure dose for the examination. Because the use of real X-ray images obtained from the patient by changing exposure dosewere prohibited, we developed a new method to simulate low-dose X-ray images by use ofthe original X-ray images and established the method for evaluating clinical utility ofsimulated low-dose images by use of receiver operating characteristic (ROC) analysis.
