A stereotactic frame is a rigid medical frame used to help locate targets inside the brain with high precision. It is attached to the patient’s head and used with imaging to create a three-dimensional coordinate system. Neurosurgeons can then guide instruments, electrodes, probes, or radiation toward a planned target. Stereotactic frames are used only by trained teams in specialized neurosurgical or radiation therapy settings.
read more about stereotactic frame ...A stereotactic frame is used when a brain target needs to be reached or treated with very precise localization. It may be used for brain biopsy, deep brain stimulation lead placement, stereotactic radiosurgery, lesioning procedures, or drainage of selected brain lesions. The frame helps match imaging coordinates with the patient’s head position during the procedure. The exact use depends on the diagnosis, target location, and treatment plan.
The frame creates a fixed reference system around the head. Imaging such as MRI, CT, or angiography is used to map the target in relation to the frame coordinates. Planning software or measuring systems then calculate the safest route to the target. During the procedure, the frame helps keep the patient’s head stable and guides instruments along the planned path.
The frame is usually secured to the skull with pins after the skin is numbed with local anesthetic. Some patients may also receive sedation depending on the procedure. Once the frame is attached, imaging is performed and the treatment plan is finalized. The frame is removed after the procedure or treatment session is complete.
A stereotactic frame can cause pressure, pin-site pain, bruising, bleeding, swelling, or skin irritation. Rare complications include infection or skull injury at the pin sites. The frame improves targeting accuracy, but it does not remove all surgical or radiation risks. Some modern procedures use frameless navigation instead, depending on the clinical goal and equipment.
Placement can cause pressure or brief discomfort, but local anesthetic is used at the pin sites. Patients should tell the team if pain becomes strong or continues.
No. A stereotactic frame is physically attached to the head, while frameless navigation uses imaging, markers, cameras, or tracking systems without a rigid head frame.
Imaging maps the target in relation to the frame so the team can calculate coordinates and plan a precise path.
It usually stays on only for the imaging and procedure or treatment session. The timeline depends on the planned procedure.
