A study has been made of CT contrast for iodine as a function of X-ray energy from 80 to 140 kV constant potential. The EMI CT 1010 scanner was used for phantom measurements of contrast signal, noise, artefact and dose. The results show that optimum detectability occurs at 80-100 kV, with the close efficiency being somewhat better at 80kV.
针对80至140 kV恒电位下作为X射线能量函数的碘CT造影进行了一项研究。使用EMI CT 1010扫描仪对造影剂信号、噪声、伪影和剂量进行体模测量。结果表明，在80 - 100 kV时可获得最佳可检测性，在80 kV时接近效率略高。
