Leksell Gamma Knife – Perfexion

Elekta perfects the art and science of stereotactic radiosurgery

Pioneered by Elekta, stereotactic radiosurgery involves delivering a single, high dose of radiation to a small and critically located target in the brain. This principle defines Gamma Knife surgery and it has dramatically widened treatment possibilities for physicians and patients.

Exceeding expectations

Leksell Gamma Knife is specifically designed for non-invasive procedures. Gamma Knife surgery provides pinpoint accuracy, unmatched efficiency and outstanding results. Patients benefit from fast, painless treatment, often conducted in an outpatient surgical setting without the need for general anesthesia or even convalescence. Over 1 million patients have undergone Gamma Knife surgery.

Setting the standard for radiosurgery

This integrated system provides full cranial reach. The system is built to deliver outstanding patient and staff comfort and better dosimetry performance than any other radiosurgical system.

Leksell Gamma Knife Perfexion the system that fuses the skills of the physician with the science of radiosurgery

The ultimate intracranial radiosurgical tool

Leksell Gamma Knife® Perfexion™ is preferred for its extreme accuracy, efficiency and outstanding therapeutic response. Today, cranial radiosurgery with Perfexion is performed in hundreds of leading hospitals and clinics around the world. Perfexion is a fully integrated system and complete solution. Every feature reflects patient and staff safety and comfort.

Proven Accuracy in Every Step

The gold standard in radiosurgery

• Guaranteed radiological accuracy of 0.50 mm¹ boosts quality of life and clinical outcomes
  ¹ With a valid service agreement
• A single robotic system with three collimators allows collimator size to automatically change, according to the treatment plan
• True stereotactic system using the Leksell® Coordinate Frame for patient immobilization

The ultimate cranial radiosurgical tool Leksell Gamma Knife® Perfexion™

Leksell Gamma Knife is consistently regarded as the best non-invasive treatment for brain disorders. So how did we make the best even better? By
listening to experts in radiosurgery and then creating Leksell Gamma Knife
Perfexion.

One-button automation

The system offers physicians a fully automated, single push-button approach to operations that translates into dramatic time savings. The cutting-edge design radically expands treatment reach to cover a wider range of anatomical structures.

Full reproducibility

Leksell Gamma Knife Perfexion offers protocol reproducibility with full backward compatibility to existing Gamma Knife surgery protocols. That means building on the treatment experience of over 1.2 million patients and close to 3,000 peerreviewed papers.

Robotic efficiency

With Leksell Gamma Knife Perfexion, the multiple helmets of the previous Leksell Gamma Knife models have been replaced by a single robotic system with three collimator sizes. Because the collimator size automatically changes according to the treatment plan, treatment times are radically reduced.

Improved workflow speeds radiosurgery

The system comes complete with Leksell GammaPlan®, the dedicated treatment planning system designed to take full advantage of the features and intelligence incorporated in Leksell Gamma Knife Perfexion. Composite Shots enable sculpting the dose distribution, which is then delivered with the unmatched accuracy associated with Gamma Knife surgery.

Unrivalled radiation protection

Every feature of Leksell Gamma Knife Perfexion reflects patient and staff safety and comfort. The system provides radiation shielding that is up to 100 times better than
alternative technologies. Room radiation levels are low enough to allow for a window into the treatment room and the system can be accommodated within a normalsized room.

Gamma Knife surgery preferred for a reason

Treatment planning Images are used to create a tailormade treatment plan to enable an optimal radiation dose to the target. The treatment plan is then transferred to the Gamma Knife system.

Treatment Targets are automatically irradiated according to the plan. Throughout the treatment procedure the patient is monitored via the intercom system.

Follow-up The effect of radiosurgery takes place over time.

With very few exceptions, Gamma Knife surgery is given on a single occasion and without general anesthesia. After Gamma Knife surgery the patient normally leaves the hospital on the same day or the day after, making it a very cost-effective alternative to open surgery.

During the procedure, 192 radiation beams from cobalt-60 sources converge with high accuracy on the target. Each individual beam has low intensity and therefore does not affect the tissue it passes through on its way to the target. The beams converge in an isocenter where the cumulative radiation intensity becomes extremely high.

By moving the patient’s head in relation to the beams’ isocenter, the radiation dose can be
optimized in relation to the shape and size of the target. The extreme precision of Leksell Gamma Knife better than 0.5 mm—makes it possible to administer a high radiation dose to the lesion with minimal risk of damaging healthy tissue.
