Abstract

A modification of the Nationwide Evaluation of X-Ray Trends (NEXT) survey procedure has been used to collect data on technique and exposure values for the A/P abdomen and A/P lumbosacral spine projection for a fixed patient size. Through the use of a sample set of patient radiographs and a phantom, technique factors and entrance skin exposure (ESE) are related to a radiograph of acceptable density. An analysis of 139 surveys demonstrates the wide range of techniques and exposures associated with each projection and suggests that ranges of typical techniques and exposure values can be defined.
