| Abstract: | After we investigated the condition of 66 viewboxs used in hospitals, we discovered that none of them are up to the standard. The maximum brightness of them is 1305 Lx, the minimum is 160LX, and the average is 760 Lx. It is far lower then the standard of Ministry of Health (the brightness of viewbox must not be lower than 1350 cd/m2, i.e. 1350 Lx). The brightness of the viewboxes is so insuff icient that it has directly had influence on the diagnosis quality.For this reason. it must be corrected imme diately. |
