Abstract
As we have an old fashioned roentgenographic apparatus (Toshiba kxo-8 x-ray apparatus), we always find some difficulties to take craniographs and pheumoencephalographs. That is the reason why we decided to make convenenient device making use of an old operation table. Though this device could be made inexpensively, it found to save us much time. One of the advantages is for us to be able to take basis craniography easily and accurately.
