Web8 de jun. de 2024 · using high kV technique is shorter exposure time [1]. The higher the energy, the more photons will penetrate the body, the less that are absorbed. Although this reduces patient dose, image quality is compromised due to reduced contrast of a preferentially forward scattered radiation [2], [3]. 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) …
