Clear AdvantagesIn addition to its very high success rate, radiosurgery with the Gamma Knife has many clear advantages:
- The Gamma Knife is a FDA approved radiosurgical device to treat metastatic brain cancer.
- The Gamma Knife offers tremendous technical accuracy, so a high dose of radiation can be delivered to a target with minimal risk to nearby tissues and structures.
- There is very little patient discomfort. The patient may be lightly sedated, but is awake throughout the procedure.
- Gamma Knife radiosurgery is an outpatient procedure and the cost is often 25 to 30 percent less than traditional neurosurgery.
Neoplastic and functional disorders represent the majority of Gamma Knife procedures. But Gamma Knife surgery also offers new hope for a variety of lesions that were often unsuccessfully treated by conventional surgery, chemotherapy or radiation therapy. The Gamma Knife's ability to create conformal and irregular dose plans makes it ideal for small brain tumors and vascular lesions that are irregular, as well as to treat multiple tumors on one treatment session. Gamma Knife treatment can be used as an alternative to open cranial-surgery or in addition to conventional surgery, microsurgery, chemotherapy, and other forms of radiation treatment.
The new Leksell GammaPlan PFX is a sophisticated treatment planning software package. It now allows virtually unlimited ability for sculpting the dose distribution, enabling composite shots and dynamic shaping with absolute accuracy. Because of this, the treatment plan effectively wraps the dose around the most complex shapes while limiting the dose to surrounding brain tissue and critical structures and deliver treatment to multiple targets seamlessly during a single session. The treatment machine sectors containing multi-source collimators are automatically positioned to use the correct collimator sizes and plugging for each target. And because of this, the treatments are more precise. For the patients, the seamless delivery of all treatments allows for shorter treatment times and increased comfort.
