Abstract

The position and form of the image layer in rotational panoramic radiography vary from one manufacture to another. A method utilizing a digital computer to calculate the position, form, and relative thickness of the image layer from data obtained from two test radiographs is described. The image layer analysis permits the performance of different rotational panoramic radiographic units to be compared independent of various parameters such as beam width and magnification. The image layers for several commercially available units are illustrated.

摘要

旋转全景X线摄影中影像层的位置和形态因制造商而异。本文描述了一种利用数字计算机根据从两张测试X线片获得的数据来计算影像层的位置、形态和相对厚度的方法。影像层分析可独立于诸如射束宽度和放大率等各种参数来比较不同旋转全景X线摄影设备的性能。文中展示了几种市售设备的影像层。
