Purpose : In sponge quality of the material in digital radiography environment coating because do positioning blocks two that do not become coating done positioning block and sponge quality of the material to testing bench image artifact's difference compare. Method of study : In digital radiography environment positioning block of different two products same sunshine or e伴ect that image and positioning block artifact gets in image analyze, the target used positioning block 2 when examine hand, rib and examination condition did each differently according to used positioning block, reflex compared picture that do image and verify that examine first time. Result - 1. In sponge quality of the material coating in done product artifact appear. Did not appear in product that do not become coating. 2. Can know coating's existence, that artifact according to radish happens. 3. Quality of the material coating's existence, there was difference of slippage according to radish Conclusion : Quality of the material coating phenomenon that done positioning block can prevent that slide but artifact of image appears show. This can become factor of image deterioration. When buy positioning block thus, it may have to be considered that use after estimate degree that get in image.
