Stereotactic radiosurgery (SRS) is a non-invasive medical procedure that utilizes advanced technology to deliver a concentrated dose of radiation to a specific area within the cranial cavity. This technique is particularly effective for treating a single, simple cranial lesion, which may include tumors or other abnormal growths. The procedure employs various forms of radiation, including particle beams, gamma rays, or linear accelerators, to target the lesion with high precision. The primary goal of SRS is to minimize damage to surrounding healthy tissue while effectively treating the lesion. The use of a rigid stereotactic frame is essential, as it secures the patient's head in a fixed position, ensuring that the radiation beams are accurately directed at the lesion. Prior to the treatment, detailed imaging studies such as three-dimensional MRI or CT scans are performed to visualize the lesion and assess its characteristics, including its location and volume. This meticulous planning is crucial for determining the appropriate radiation dose and for evaluating the potential risks to adjacent structures. Stereotactic radiosurgery is a sophisticated procedure that exemplifies the integration of imaging technology and radiation therapy, providing a targeted approach to managing cranial lesions.
