Patient dosimetry measurements in 50 radiology departments in Belgium.

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.
