内容記述タイプ | Abstract | |||||
内容記述 | In this paper, we have studied the improvement method of the Computed Radiography(CR) images. The picture quality of CR image degrades with scattered radiation. This problem can be sett1ed using a grid, but a dose is increase. We examined the signal processing fi1ters which substitutes for the grid. We tried a Kasvand-type unsharp masking which combined the Kasvand operator with the conventional unsharp masking. We could improve a picture quality of CR images which cannot be improved by a conventional unsharp masking. | |||||
