Highest Accuracy - 0.15 mmLeksell Gamma Knife® Perfexion™ combines a patented collimator design with a revolutionary new positioning system to e!ectively wrap dose around the most complex shapes while limiting dose to surrounding tissue and critical structures. Dose delivered by each individual beam falls from 80% to 20% in about 1 mm, creating a penumbra that dramatically illustrates how Leksell Gamma Knife Perfexion is able to deliver highly e!ective treatments. "e average accuracy of a Leksell Gamma Knife is 0.15 mm during its lifetime.*

User Satisfaction: Leksell Gamma Knife® Perfexion™ had the highest overall rankings by a 10 point margin. The 2011 KLAS Radiation Oncology and TPS report.
Treats brain disorders with a high dose of radiation delivered with surgical precision.
Radiation unit
20ton
With the treatment planning software, Leksell GammaPlan, the shape and amount of radiation is decided to give an optimal treatment.
Leksell Gamma Knife Perfexion is fully automated. The radiation unit is housed inside of the machine itself. The radiation beams are shaped exactly around the tumor. Several tumors can be treated in one session.
The patient can communicate via video camera and an intercom at all times. The treatment time varies between 20 minutes and several hours depending on the complexity of the treatment.
Perfexion is designed to treat patients with di!erent types of brain disorders.
A stereotactic frame is attached to the patients
head and interlocked to the Gamma Knife unit. This to ensure maximum precision.
Ionizing gamma radiation is emitted from
192 cobalt-60 sources whose beams converge on a precise selected area of the brain. The accuracy is about 0.5 mm. There is minimal e!ect on the surrounding healthy tissue.
