摘要
本文报道北京地区191台医用诊断 X 射线机的、与影像质量有关的基本参数的测试结果。并对影响这些性能参数的原因进行了分析。结果表明,北京地区现有 X 射线机的性能及运行状况存在着不少问题,为了保证 X 射线影像质量及诊断效果,减少受检者剂量,必须对医用诊断 X 射线机进行质量控制。
In this paper,the results of test for their essential parameters concerned in image quality of191 X-ray diagnostic equipments used in hospitals of Beijing were reported and an analysis of factorshaving influence on these performance was given.The results show that for these X-ray diagnosticequipments,there are several problems in their performance and operation.In order to assume the qual-ity of images and reduce the dose to patients,the quality control must be implemented for these X-raydiagnostic equipments.
