| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Objective evaluation, e.g. using MTF or NPS, of X-ray imaging system may not correctly correspond to subject evaluation, e.g. using ROC. Moreover, it is difficult to measure MTF or NPS from clinical images. Therefore, we introduced MTF fractal dimension to X-ray imaging system. The MTF fractal dimension includes frequency properties of human eyes in addition to quantitative complexity. In this study, we conducted an observer performance study using chest X-ray images with subtle simulated nodules, and also measured MTF fractal dimension from the same images. The measurement results of MTF fractal dimension tended to be similar to the results of observer performance study. Therefore, we consider that MTF fractal dimension may become an index of image quality in medical X-ray imaging system. | |
