While patient entrance surface dose rate is an important indicator of dose
performance for fluoroscopic units, there has been no standardized approach
to measuring this. Since results are strongly dependent on the type of pha
ntom used and the relative positions of the X-ray tube, intensifier and pha
ntom, comparisons of the performance for different units are difficult to m
ake. This document sets out a protocol for making these measurements using
a standard phantom and standard configurations for different types of X-ray
unit. Values of dose rates which might be expected are given.
