[Computed tomographic stereotaxy: development of a new system].
We present a newly developed stereotactic apparatus for use with conventional roentgenograms and computed tomography. The geometrical dimensions and proportions of the apparatus render a calculation of target coordinates redundant. It incorporates all the required safety and precision. Two independent targeting devices can be mounted to the headholder. Thus the apparatus encompasses, to a large extent, present and future developments towards efficient and less invasive brain operations.
