Stereotactic Radiosurgery (SRS) and Stereotactic Radiotherapy (SRT) are highly advanced radiation techniques designed to deliver extremely precise, high-dose radiation to tumors with sub-millimeter accuracy. These techniques focus intense radiation beams directly on the tumor while minimizing exposure to surrounding healthy brain or body tissues.
SRS is typically delivered in a single session, whereas SRT is given in multiple carefully planned sessions. Both approaches are non-invasive and do not require surgical incisions, making them effective alternatives to conventional surgery in selected cases.
The treatment process begins with detailed imaging using advanced CT, MRI, or PET scans to accurately map the tumor location. Specialized planning software is used to design a customized radiation plan that ensures maximum dose delivery to the target while protecting critical structures.
During treatment, patients are positioned carefully to maintain accuracy and comfort. Image-guided verification is performed to ensure precise radiation delivery. Most patients can resume normal activities shortly after the procedure.
SRS and SRT represent modern, high-precision radiation oncology solutions that provide effective tumor control with minimal side effects, offering safe and targeted treatment for complex brain and small body tumors.
