Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT)
The concept of Stereotactic Radiation Therapy (SRS) and Stereotactic Body Radiotherapy (SBRT) is state-of-the-art technology in radiotherapy and is one of the most advanced, sophisticated technologies of its type in the world.
The concept is to destroy tumors inside the body with the accuracy of a knife blade, almost like cutting them out but using a non-invasive method.
- Allows delivery of radiation therapy to the region of abnormality with unprecedented submillimetre accuracy
- SRS uses multiple beams of radiation that all converge on a single point, or an area says tumor and ablation it.
- SRS or SBRT delivers one to five stereotactic radiation treatments to tumors within the brain, spine, and elsewhere in the body.
- All inoperable tumours and patients who are not fit for surgery can still be cured with this high dose of ablative radiation treatments.
- A 4-dimensional cone beam CT scanner mounted on the treatment machine assists in accurately delineating tumors that move during the treatment time.
Symmetry planning software is a new approach to the treatment of thoracic tumors. It aids to reduce margins by using unique, automatically correlated 4D image guidance. It gives volumetric visualization of respiratory motion and enables radiation oncologists to reduce margins and increase the dose without compromising safety. It also helps to deliver a ‘plan of the day’ customized to the tumor’s movement.
6-dimensional couch allows delivery of this state-of-the-art treatment with unprecedented accuracy.
