X-raying the entire spinal column in the standing position in a single exposure (mainly the AP projection) is an often-used chiropractic radiography procedure which has also found some application in medical scoliosis screening program. Aside from any controversy of clinical objectives or medical necessity, the primary agreed-upon requisite for such procedure is twofold; achieving the best possible film image quality with the least amount of radiation exposure to the patient. A popular method of accomplishing this objective is by the use of collimator-attached devices designed to selectively filter the primary x-ray beam in accordance with regional variations of body thickness and/or density. This study was conducted to evaluate the use of a new lead-acrylic filter system (a prior model of which had previously been evaluated for its use in medical radiography) under specialized chiropractic conditions. In comparison to other available systems, it was concluded that this new system; a) is generally equivalent in its radiation dose reduction capabilities; b) is capable of producing full spine radiographs with good to above average image quality; and c) is appreciably easier to use.
在站立位单次曝光（主要是前后位投照）对整个脊柱进行X线检查是脊椎按摩疗法中常用的一种放射照相程序，在医学脊柱侧弯筛查项目中也有一定应用。除了临床目标或医学必要性方面的任何争议外，这种程序首要的、大家公认的必要条件有两个方面；在使患者接受最少辐射暴露的情况下获得尽可能好的胶片图像质量。实现这一目标的一种常用方法是使用带有准直器的装置，该装置设计用于根据身体厚度和/或密度的区域差异选择性地过滤初级X线束。本研究旨在评估一种新型铅丙烯酸滤光系统（其先前型号曾在医学放射照相中进行过使用评估）在特殊脊椎按摩疗法条件下的使用情况。与其他现有系统相比，得出的结论是，这种新系统：a）在辐射剂量降低能力方面总体相当；b）能够生成图像质量良好至高于平均水平的全脊柱X线片；c）使用起来明显更简便。
