This material is used to create a means for reproducibly positioning the head prior to the scan. This material is perforated so that the patient can see outside the mask. The mask does not cover the mouth or the nose, so that breathing is not impeded. The Scan With the mask in place the scan is obtained. No attachments to the skin are made.
All hardware is external to the patient, without incisions, anesthesia or drugs.
This means that the location of the frame is shown on the scan along with the intracranial tumor. Therefore, both the frame and the brain tumor can be simultaneously visualized and precisely localized for the subsequent treatment planning and treatment of the brain tumor. This special device is dedicated to the treatment planning for radiosurgery. No hospitalization is necessary for this non-invasive procedure. After the simulation the treatment planning begins.
