Physical performance testing of Mobetron 2000 mobile intraoperative radiotherapy system
摘要
Abstract
Objective To execute physical performance testing of Mobetron 2000 mobile intraoperative radiotherapy system.Methods Mobetron 2000 mobile intraoperative radiotherapy system had its indexes measured according to TG51 protocol such as percent depth dose (PDD),output dose,beam energy,field flatness and symmetry,X-ray pollution,dose linearity and repeatability.Three-dimensional water phantom was used for verification and acceptance when the measurement was executed,while the calimator end was tangent to the water surface and the nominal ource-skin distance was 50 cm.Results All the indexes of the system met the desired requirements except 12 MeV beam energy.Conclusion The system can be promoted clinically for safe,reliable and efficient treatment.关键词
