Study Notes
Stereotactic Irradiation Overview
- Stereotactic irradiation consists of techniques that utilize multiple non-coplanar photon radiation beams.
- It delivers a precise dose of ionizing radiation to targeted lesions that are pre-selected and localized stereotactically.
Equipment Used in Stereotactic Radiosurgery
- Stereotactic Frame: Establishes a fixed coordinate system to accurately locate and deliver treatment to the planning target volume (PTV).
- Imaging Equipment: Includes CT, MRI, and Digital Subtraction Angiography (DSA) for visualizing, defining, and localizing structures, lesions, and the PTV.
- Target Localization Software: Works with the stereotactic frame and imaging equipment to calculate the coordinates of the target within the stereotactic reference system.
- Treatment Planning System: Computes the three-dimensional dose distribution and overlays it onto the patient's anatomical data.
- Radiation Source: Requires appropriate sources and techniques for performing radiosurgery.
Radiosurgery Techniques
- Gamma Knife Machines: Primary tool used for stereotactic radiosurgery.
- Modified Isocentric Linacs: Also significant in conducting radiosurgical procedures.
- CyberKnife: Features a miniature linear accelerator (linac) mounted on a robotic arm for advanced precision in treatment.
- CyberKnife has been in clinical use since the mid-1990s, with over 50 machines operational worldwide by 2005.
Target Localization
- Target localization crucially employs imaging modalities like CT and MRI to ensure accuracy in targeting lesions for treatment.
