Stereotactic systems are a type of medical technology used for targeting precise locations within the body for diagnostic or therapeutic purposes. The term “stereotactic” refers to the use of three-dimensional coordinates to locate a specific point within the body.
Stereotactic systems can be used for a variety of medical applications, including neurosurgery, radiation therapy, and biopsy procedures. These systems typically use a combination of imaging technology (such as MRI or CT scans) and specialized instruments to accurately target the desired location within the body.
The basic components of a stereotactic system include a frame or platform that is attached to the patient’s body, imaging equipment to generate images of the target area, and specialized instruments (such as a biopsy needle or surgical tool) that can be precisely guided to the target location.
There are several different types of stereotactic systems, each with its own unique features and applications. Some of the most commonly used systems include:
- Frame-based stereotaxy: This type of system uses a rigid frame that is attached to the patient’s skull or other part of the body. The frame serves as a reference point for the imaging equipment and allows for precise targeting of the desired location.
- Frameless stereotaxy: This type of system uses a non-invasive imaging technique (such as MRI or CT) to create a virtual 3D model of the target area. This model is then used to guide specialized instruments to the target location without the need for a rigid frame.
- Robotic stereotaxy: This type of system uses robotic arms to guide specialized instruments to the target location. The robotic arms are controlled by a computer system that can be programmed to perform precise movements with high accuracy.
Stereotactic systems have revolutionized many areas of medicine, particularly in the fields of neurosurgery and radiation therapy. By allowing for precise targeting of specific areas within the body, these systems can help to minimize damage to surrounding tissues and improve patient outcomes.
