Web17 de mai. de 2008 · For high kV technique, the greater tissue density leads the bone to have greater rate of radiation absorption. It means, fewer photons reach the image receptor and construct less image receptor exposure. That is why bones appear whiter on radiograph. Also the high kV needed to penetrate the bones. WebHigh kilovoltage radiography had its beginning with super-voltage technique and is presently accomplished with the 350 KV chest x-ray system. The physical reasons to explain the improved visibility with this technique are: (1) absorption coefficients of bone and soft tissue, (2) more uniform bone visibility, (3) x-ray spectrum, (4) visual responses, and (5) …
