Only a few years following its original development by the English physicist G.N. HOUNSFIELD, cranial computerized tomography has proved to be of revolutionary importance for the diagnosis of brain disorders. This is reflected not l~ast by the almost immediate and worldwide ac- ceptance of this diagnostic method. Meanwhile, computerized tomography has in addition led to a considerably improved diagnosis of lesions within the orbital region. With the technically advanced systems of the second generation that will soon be available, the method can also be applied to the study of pathological processes of the facial region of the skull and the neck as well. Finally, although at present still at the stage of clinical investigation, the whole-body scanning system will enable investigation of all parts of the body. Stimulated by the successful 1st and 2nd Internalional Symposium on Computerized Tomography held in Hamilton, Bermuda, in ~'arch 1975 and in San Juan, Puerto Rico, in April 1976, we organized a meeting on cranial computerized tomography which took place in ~unich, June 10 to 12, 1976.
It was the aim of this symposium to provide basic informa- tion as well as to exchange the experiences with the new method.
