Computed tomography guidance for stereotactic localization

What is a stereotactic CT scan?
The term “stereotactic” refers to the use of a three-dimensional coordinate system combined with an imaging technique, such as computed tomography (CT) scanning or magnetic resonance imaging (MRI), to precisely locate targets deep within the brain..
What is Stereotaxic lesion localization?
Stereotactic localization requires a fixed coordinate system.
The breast is placed between a compression plate and back breast support to keep the lesion in a fixed position during the procedure..
Stereotaxis is an improved method of catheter ablation that helps doctors have control over the movement of the catheter.
This non-surgical treatment for arrhythmia uses a remote magnetic navigation system to create three-dimensional images to help map out the artery and heart tissue to be treated.

CT stereotactic guidance systems of modern design provide the neurosurgeon with a precise methodology in approaching intracranial targets. These systems eliminate the potential inaccuracy of freehand approach, no matter how skilled the neurosurgeon.

Stereotactic localization using computerized tomography (CT) is increasingly employed to guide neurosurgical procedures in crucial areas of the brain such as the brain stem. This technique allows the surgeon to resect a lesion in its entirety while sparing critical areas of the brain.

The N-localizer is a device that enables guidance of stereotactic surgery or radiosurgery using tomographic images that are obtained via computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET).
The N-localizer comprises a diagonal rod that spans two vertical rods to form an N-shape and permits calculation of the point where a tomographic image plane intersects the diagonal rod.
Attaching three N-localizers to a stereotactic instrument allows calculation of three points where a tomographic image plane intersects three diagonal rods.
These points determine the spatial orientation of the tomographic image plane relative to the stereotactic frame.

Medical procedure

Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
