Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
Gamma knife surgery is a form of radiotherapy, more specifically radiosurgery that uses beams of gamma rays to deliver a certain dosage of radiation to the tumor. Gamma knife surgery is incredibly effective at treating neurocytoma and maintaining tumor control after the procedure when a complete excision has been performed.
The Gamma Knife relied on a stereotactic frame screwed into the patient's skull as an external surrogate to triangulate the location of the subject's tumor; Adler instead wanted to rely on recent medical imaging advancements and internal anatomical structures to guide the beam. Dr. Adler also sought to eliminate the costs to secure and ...
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.
It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy , and has been used before, during, and after chemotherapy in susceptible cancers.
During treatment, the image guidance system captures 3D images, tracks the movement of tumors, and guides the robotic arm to accurately aim the treatment beam at the moving tumor. [2] The system is designed for stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT).
