[A new method of autotomography in cerebral angiography (author's transl)]

Acompanied with the recent advances of various techniques of cerebral angiography, the angio-tomography is now going to be recognized as one the significant techniques. But, this angio-tomography requires a special work place with tomographic equipment. Thus the applicability of the method is now limited as far as the routine use is concerned. So, the technique of autotomography is often tried as a convenient substitute for the angiotomography, because this technique is very simple and does not need any special facilities. But, as the autotomography is only possible to take the midline tomogram, it's application is strictly limited. So, we have invented a new method of the autotomography using a simple device. This device is constituted of two portions; one is a plate of rotation, and the other is a box to fasten a patient's head. By sliding the box on the plate, it is possible to move the rotatory axis to the aimed portion of the head. In this way, it is possible to take an arbitrary tomographic plane. As our device is simple and it's use is very easy, this method of the autotomography is possible to apply in a routine examination. This report describes the principle and the method of the use of our new device and demonstrates several films taken by this method.
