The collimator arrangement and the patient positioning system also allow shorter patient transit times, reducing unwanted radiation exposure during movement between isocenters. No other non-invasive treatment method in this field has greater clinical acceptance.

Series of 28 Cases. This site uses cookies. Despite increasing the treatment range, the average source-to-focus distance is still kept very close to previous ggamma due to an improved design of the collimator system of LGK PFX. You could not be signed in. The docking of the patient into the PPS is done by means of a frame adapter that attaches to the standard stereotactic Leksell G frame with the help of three clips.

pervexion Before exposing the films to radiation, the films were punched with a needle. The primary and secondary collimators of previous models have been replaced by a single large mm thick tungsten collimator array ring. Related articles in Google Scholar.

System without compromise Icon is specifically designed for intracranial radiosurgery and has unique dosimetrical capabilities. Pathologies previously inaccessible in the head and neck are now treatable due to the increased volume of the radiation cavity. Design and performance characteristics are compared with previous models of the gamma knife in a clinical setting.


IOP Publishing Ltd; The perfexkon is improved image quality for better image guidance.

The Leksell Gamma Knife Perfexion and comparisons with its predecessors.

Each GammaKnife contains about Co radioactive sources that are used to non-invasively deliver a high dose of radiation to treat brain disorders.

Today, cranial radiosurgery with Perfexion is performed in hundreds of leading hospitals and clinics around the world.

Different sector colors indicate different collimator size used: Non-uniform output from the sectors will affect the isodose pattern during irradiation but such an effect will not be accounted perfexxion by the Leksell GammaPlan software, which assumes output from each sector to be uniform.

Keeping a high score of PCI indicates good conformity of a treatment plan and keeping a low value of GI indicates low dose to the surrounding tissue.

The PPS provides a more comfortable position for the patient during treatment. Icon is the only technology with microradiosurgery capabilities allowing for the treatment of virtually any target in the brain with ultrahigh gammw. Leksell Gamma Knife Icon is the most precise radiosurgery device on the market, limiting radiation dose to healthy tissue.

Performance-related features in the design of the new radiosurgical system are described, and the ability to create complex shapes of isodose volumes even with a perfexioh isocenter is demonstrated. Perfexion is a fully integrated system and complete solution.


First clinical experience with the automatic positioning system and Leksell gamma knife model C, Technical knire. Such a composite shot allows for optimized dose distribution shape for the individual shots.

Leksell Gamma Knife® Perfexion™

A patient can now be positioned on the treatment couch and then imaged without moving from one device to another.

Stereotactic radiosurgery of the brain using the lekesll United States cobalt source gamma knife. Lower dose to healthy tissue times lower dose to healthy lekxell and lowest dose to rest of body compared to other SRS modalities 2 2 Ma L, Nichol A, Hossain S, et al. The beam size for each region is changed automatically by moving 24 sources over selected collimator set. Sunnybrook Health Sciences Centre- A distributed and efficient method to treat multiple mets.

From Simple Decompression to Sling Transposition. This results from the enhanced ability to shape isodose volumes, even for single isocenters. Fully automated treatment delivery allows for small teams and high throughput regardless of treatment volume.
