Hospital staying considered the time necessary for any procedures related to treatment, not only the biopsies. Stereotactic surgery or stereotaxy is a minimally invasive form of surgical intervention which makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablationbiopsylesioninjection, stimulationimplantation, radiosurgery SRSetc.

The application accuracy of stereotactic frames.

The software used for neuronavigation was Cranial Navigation v. However, target motion requires larger treatment margins around the target to compensate for the positioning uncertainty. We did a retrospective analysis of two groups: Accepted 29 July There are four cases of frame-based biopsies not ceebral on this table: In humans, the reference points, as described above, are intracerebral structures which are clearly discernible in a radiograph or tomograph.
