摘要
目的:研究模拟定位机图像工作站在二维适形挡块制作和验证中的应用。方法:获取患者图像,放疗医师在图像上勾画铅挡块轮廓,传输到自动切割机制作挡块,将制作完成的挡块在模拟定位机下验证合格后再在直线加速器上拍片验证。结果:1371块铅挡块中,在模拟定位机上初次验证合格的有1107块,合格率80.7%;经模拟定位机验证合格后,1371块铅挡块在直线加速器上拍片验证,合格的有1345块,合格率98.1%。结论:模拟定位机的图像工作站可提高挡块的制作效率,减少挡块制作的误差环节。
Objective To apply simulator image workstation to making and verification of integrated blocks. Methods The outline of blocks drawn by doctors at simulator image workstation were transferred to the auto-cutting machine. The blocks were fabricated and were verified by the simulator. Then the qualified ones were verified by the linear accelerator. Results Of 1 371 blocks selected to verify by the simulator, 1 107 （80.7%） blocks were qualified; Of 1 371 blocks qualified by the simulator, 1 345 （98.1%） blocks were qualified by the linear accelerator. Conclusion Simulator image workstation can improve efficiency and reduce the error in making blocks.
