Radiographic stereoplotting is a method for taking three-dimensional measurements from a pair of x-ray films. The x-ray technique is described, as is the stereoplotter. Using this machine it is possible to locate any point within the patient and measure the distance between that point and any other point. From this information it is possible to compute areas, volumes, and angles with great accuracy, which hitherto has been impossible using noninvasive techniques. It is planned to take measurements of the spinal canal in normal backs and in patients with nonspecific back pain, in order to try to define some of these syndromes on a structural basis. It is likely that stereoplotting has some useful application in most branches of clinical medicine, since the x-ray technology is available in any diagnostic x-ray department.
X射线立体绘图是一种从一对X光片进行三维测量的方法。文中描述了X射线技术以及立体绘图仪。使用这台仪器能够确定患者体内的任何一点，并测量该点与其他任何点之间的距离。根据这些信息，可以非常精确地计算面积、体积和角度，而这在以往使用非侵入性技术是无法做到的。计划对正常背部和非特异性背痛患者的椎管进行测量，以便试图从结构基础上界定其中一些综合征。由于任何诊断性X光科室都具备X射线技术，立体绘图很可能在临床医学的大多数分支中都有一些有用的应用。
