模拟定位机影像工作站在适形挡铅制作与质量控制中的作用

摘要

Objectivt:To study on the role of simulator image workstation in making and quality assurance of low melting-point blocks.Methods:The blocks were fabricated according to the outline drawn.The simulator was used to verify the blocks and the errors were found at image workstation.Results:The error of 500 lead blocks were measured at image workstation and 398 blocks were qualified and the others unqualified.Conclusion:Simulator image workstation can convenientey make blocks and improve quality of blocks.%目的:研究模拟定位机的影像工作站在放射治疗适形挡铅的制作与质量控制中的作用.方法:在影像工作站上勾画挡铅轮廓,制作挡铅,然后在模拟定位机上验证挡铅,利用影像工作站测量挡铅的误差.结果:随机选取500块挡铅进行分析,通过模拟定位机验证,有398块合格(79.8%);有 102块不合格(20.2%).结论:模拟定位机的影像工作站,可以方便挡铅的制作,提高挡铅的质量.
