Abstract

The beam and performance characteristics of a new orthovoltage X-ray unit, the Pantak DXT-300 have been evaluated. Data were collated for four qualities: 3.27 mmAl, 7.15 mmAl, 1.65 mmCu and 3.51 mmCu half value layer (HVL) (SE = 0.04 mm). Parameters which were investigated included beam quality, central axis depth dose, relative output, backscatter factors, field uniformity, peripheral dose and head leakage. The calibration procedure and the performance of the dosimetry system have also been described.

摘要

对一款新型正电压X射线装置——潘塔克DXT - 300的射线束和性能特征进行了评估。整理了四种品质的数据：3.27毫米铝、7.15毫米铝、1.65毫米铜和3.51毫米铜半值层（HVL）（标准误差 = 0.04毫米）。所研究的参数包括射线束品质、中心轴深度剂量、相对输出、反向散射因子、射野均匀性、周边剂量和头部泄漏。还描述了校准程序和剂量测定系统的性能。
