Traditional Cerebral Stereotaxy is cumbersome, slow, and expensive. Image guided "Frameless Stereotaxy" units require expensive intra-operative workstations, image/patient registration and computer knowledge. The Anatomics solution for stereotaxis is simple and cost-effective, allowing accurate biopsy of cerebral lesions, surgical navigation, and the delivery of Brachytheraphy. Biomodel guided stereotactic surgery uses a solid BioModel replica of a patient to provide the anatomical data needed for trajectory planning. This concept forms the basis of a method of stereotaxy that can be performed using a number of different apparatus.

The method is as follows:

1. The patient undergoes CT scanning and a biomodel is manufactured.
2. An apparatus is attached to definable points on the replica.
3. The apparatus is used to create an operative plan so that interventional co-ordinates are able to be saved (e.g. a trajectory is defined to localise a target).
4. The apparatus is transferred and attached to the patient via common definable points.
5. The intervention is repeated on the patient using the saved co-ordinates.

This original method has been validated by the use of different apparatus in phantom studies and actual patient studies. The techniques use resection templates or the Anatomics Stereotaxy Frame. Each approach is described in the links below:
