QUALITY CONTROL IN INTERVENTIONAL DIAGNOSTIC RADIOLOGY &#8212 ; EXTERNAL DOSIMETRY &#8212 ; DIGITAL DOSIMETERS

The measurements we wish to present were performed according to new dosimetric philosophy concept where radiation exposure is recognised as a private/or group hazard of each person involved in the procedure of evaluation of diagnostic radiology images/diagnosis. The important quality elements of the diagnostic radiology imaging process are the diagnostic quality of the radiographic image, the radiation dose to the patient and the choice of the radiographic technique. This depends on the X-ray unit (tube) radiation quality, image processing quality and finally, image evaluation quality. If seen during the interventional radiology procedures these elements are to be considered with a different weight as in common diagnostic. A team performing the intervention is directly occupationally exposed and the radiologist is the person who has to fulfil the diagnostic-evaluation of diagnostic radiology images in real time. Real time means that the decisions depend just on considering the real time diagnostic image on the X-ray equipment monitor. In this paper we will show how the Quality Control measurements and the use of digital dosimeter with direct readout and memory options for external dosimetry/environmental monitoring can be used to establish the occupational dose delivered to the staff and dose delivered to the patient for the known diagnosticinterventional procedure. The private/group hazard will be discussed and methodology of introducing the measurements in radiographers daily work will be introduced
