Since July 2001, the Belgian law requires a yearly quality control measurement on all medical radiological equipment. The medical physicists of the AV Controlatom are certified experts in Belgium and perform these quality control measurements, including a patient dosimetry study. In this study, patient dosimetry results since January 2002 are presented for the following examinations: chest PA and LAT, abdomen and pelvis. Since conventional film-based imaging is currently being replaced by phosphorplate technology, a comparison between both technologies is made. In some radiology departments, digital imaging is already in use. These dosimetry results are also analysed. Dose reductions of >70% can be achieved. For the chest examinations, several departments still use fluoroscopy for positioning the patient. Results show that about half of the patient dose is due to the fluoroscopy. A comparison between the dose results and the European Diagnostic Reference Levels (EDRL) is made.
自2001年7月起，比利时法律要求对所有医用放射设备进行年度质量控制测量。AV Controlatom的医学物理师是比利时的认证专家，负责进行这些质量控制测量，包括患者剂量学研究。在本研究中，给出了2002年1月以来以下检查的患者剂量学结果：胸部正位和侧位、腹部和骨盆。由于传统的基于胶片的成像目前正被磷光板技术所取代，因此对这两种技术进行了比较。在一些放射科，数字成像已经在使用。这些剂量学结果也进行了分析。可以实现超过70%的剂量降低。对于胸部检查，几个科室仍使用荧光透视来为患者定位。结果表明，约一半的患者剂量是由荧光透视造成的。将剂量结果与欧洲诊断参考水平（EDRL）进行了比较。
