Stereotactic Headring

Overview

Overview
The Stereotactic Headring is an invasive stereotactic fixation system. It prevents the patient's
head from moving and minimizes errors during patient setup. Only one screw needs to be
loosened to adjust the headring for the patient's anatomy.
The Stereotactic Headring is a hardware component that is used for invasive patient
immobilization with highest positioning accuracy. It is used for CT or x-ray scan procedures as well
during single fraction radiotherapy or radiosurgery treatments. The main frame of the Headring is
fixed to the patient's head in a rigid position by fixation pins which are screwed against the skull.
The Stereotactic Headring is for single fraction treatments only. It is not intended for multi-
fractional treatment.
Do not use the Stereotactic Headring in an MR, PET, or SPECT environment.
Do not use the headring on patients under eight years of age.
