Quality control in diagnostic radiology - patient dosimetry

Abstract

In order to establish the Quality Criteria for diagnostic radiographic images in the radiology departments in Republic of Croatia we have started the several Quality Control projects on the field. The measurements are performed according to some methodology recommendations in our law but the methodology, measurement principles, measurement equipment, phantoms, measurable parameters for the good use by radiographers, statistical and numerical evaluation, dosimetric philosophy etc. where first recognized 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 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 final image evaluation quality. In this paper we will show how the Quality Control measurements can be easily connected to the dose delivered to the patient for the known diagnostic procedure and how this can be used by radiographers in their daily work. The reproducibility of the x-ray generator was checked before the service calibration and after the service calibration. The table of kV dependence and output dose per mAs was calculated  More>>

The reproducibility of the x-ray generator was checked before the service calibration and after the service calibration. The table of kV dependence and output dose per mAs was calculated and the ESD (entrance surface dose) was measured/calculated for the specific diagnostic procedure. After the phantom calculation were made and the dose prediction for the given procedure was done, measurements were done on the patients (digital dosemeters, TLD and film dosemeter combinations). We are claiming that there is no need to measure each patient if the proper Quality Control measurements are done and the proper table of ESD for each particular x-ray tube in diagnostic departments is calculated for the radiographers daily use.
