[en] There are two main approaches to the establishment of reference doses for digital fluoroscopy/fluorography equipment. One involves the measurement of dose/image and dose rate when a suitable patient-equivalent phantom is placed in the primary beam. The other is based on the analysis of the results of a series of patient dose measurements for different examinations. Both methods have their advantages and disadvantages. The former can be incorporated into a programme of quality assurance measurements and facilitates comparison between different digital fluoroscopy units. Unfortunately there is no international scientific agreement on measurement protocols or standards, and the measured values are also critically dependent on the settings used by the automatic exposure control. Patient dosimetry measurements can be performed and have the advantage that risk and detriment can be determined for specific individuals. However, the effect of patient variability in terms of size and composition makes comparisons difficult. The results of a regional survey of digital fluoroscopy/fluorography equipment is presented and discussed in relation to the overall context of the meeting objectives (i.e. reference doses and quality assurance).
