摘要 剂量学验证是放射治疗中质量保证的重要一环,也是调强适形放射治疗(IMRT)应用于临床时必不可少的一个步骤,随着放射物理技术的发展,新设备和新方法在不断应用,为临床放射治疗提供了更好、更便捷的质量保证与控制手段。二维电离室矩阵(MatriXX)是一种快速的剂量测量系统,是目前较先进的调强治疗实时二维验证系统之一,它可以测量照射野的剂量分布和强度分布,在剂量学验证中,可以极大地简化验证工作量,提高验证效率。 Dosimetry verification is an important ring in quality assurance for intensity-modulated radiation therapy (IMRT) and is an indispensable procedure in clinlic, with the development of radiation physics technique, new devices and new methods have been applied constantly. They provide us to do the better and more convenience in quality assurance for IMRT, two dimensional ionization chamber array (MatriXX) is a quick dose measurement system, and one of the most advanced two dimensional dose verificatiou system in IMRT at present. It may measure dose distribution and intensity distribution in field size. It may reduce workload and raise efficiency of dosimetry verification in IMRT.
