Modification of the Talairach Stereotactic System for CT-Compatibility: Technical Note

Summary

A modification of the Talairach stereotactic system is described which is able to incorporate CT data and provides both co-ordinate calculations, directly from the CT console screen and by a fiducial reference system. The device maintains the original base plate, thus allowing its interfacing with all the accessories of the early apparatus and its direct use in the stereotactic operating room. The instrument has shown great reliability in the localisation of brain lesions and considerable flexibility in many stereotactic operations such as biopsy procedures, brachytherapy, radiosurgery and stereotactically assisted resections.
