What is stereotactic frame?
A stereotactic head frame is employed to provide reference points for targeting. At the beginning of the procedure, the frame is attached to the patient’s head using local anesthetic to numb the scalp. An indicator box is then attached to the head frame, and an MRI or CT scan is obtained.
What is stereotactic image guidance?
Stereotactic image-guided surgery uses 3-D imaging technology to locate tumors and lesions in the spine and fix their location for optimum placement of surgical instruments.
How do you use stereotaxic frames?
Mount the animal onto the stereotaxic apparatus by placing the ear bars into the ear canal and tightening into place. First mount one ear bar in the ear canal, and then hold it in place and slide in the other ear bar. You know you are in the correct location when the head can no longer be moved side to side.
What is a stereotaxic apparatus used for?
A stereotaxic device uses a set of three coordinates that, when the head is in a fixed position, allows for the precise location of brain sections. Stereotactic surgery may be used to implant substances such as drugs or hormones into the brain.
What is stereotactic localization?
Stereotactic mammography is used to ensure accurate needle placement when localizing non-palpable breast lesions. Once the localization needle is inserted into the breast, it is recommended that its position should be checked with a further stereo-image film. The interpretation of these check films can prove difficult.
What is stereotactic craniotomy?
This technique requires the use of a frame placed onto the skull or a frameless system using superficially placed markers or landmarks on the scalp. When either of these imaging procedures is used along with the craniotomy procedure, it is called stereotactic craniotomy.
Is stereotactic and stereotaxic same?
stereotaxic surgery, also called stereotactic surgery or stereotaxy, a three-dimensional surgical technique that enables lesions deep within tissues to be located and treated using cold (as in cryosurgery), heat, or chemicals.
How is a stereotactic biopsy done?
Stereotactic mammography pinpoints the exact location of a breast abnormality by using computer analysis of x-rays taken from two different angles. Using the calculated computer coordinates, the radiologist inserts the needle through a small cut in the skin, then advances it into the lesion and removes tissue samples.
Who performs stereotactic radiosurgery?
The radiation therapist will position you with guidance from the radiation oncologist based on these x-rays. The radiation therapist will then deliver the treatment. Sometimes, x-rays or a CT scan will be taken during the treatment to monitor the position of the tumor. Treatment can take up to one hour or more.
What is Sabre treatment?
Stereotactic ablative radiotherapy (SABR), also known as stereotactic body radiation therapy (SBRT), is a highly focused radiation treatment that gives an intense dose of radiation concentrated on a tumor, while limiting the dose to the surrounding organs.
