摘要
Abstract
Objective To verify the feasibility and reliability of using solid phantom for absorbed dose measurement and analyze the measurement result. Methods The dosimeter was used to measure the absorbed dose of Varian23EX medical linear accelerator in solid phantom and standard water phantom at the depth of calibration,and the correction factor of solid phantom versus standard value was given. Results The ratio of absorbed dose measured by home-made solid phantom and standard water phantom was betwcen 0.980-1.010. Conclusion The ABS resin home-made solid phantom, which is easily used and less complicated to operate and with a good repeatability, can be used to measure absorbed dose with the use of correction factor for the measurement correction.[Chinese Medical Equipment Journal , 2011 , 32 ( 4) : 16-18]关键词
