前言近年来,X 射线检测又有所发展,建立三维 X 射线图象也是其内容之一。CT 装置可说是这方面工作的一个代表。然而,该装置较为复杂,价格又昂贵,限制了它的应用。这里介绍的一种方法,只要运用常规X光机(当然有一定要求)和一些简单装置即可获得三维 X 射线图象。 Foreword In recent years, X-ray detection has been developed, the establishment of three-dimensional X-ray images is also one of its contents. CT device can be said to be a representative of this work. However, the device is more complicated and costly, limiting its use. One of the methods presented here, as long as the use of conventional X-ray machine (of course, have certain requirements) and some simple devices to obtain three-dimensional X-ray images.
