Complement your competence with Leksell Gamma Knife
Lars Leksell created the Gamma Knife while searching for an alternative to open surgery for functional indications. Designed with the neurosurgeon in mind it delivers the necessary submillimeter accuracy and low dose to healthy brain tissue when treating intracranial indications. These days it is considered a proven, reliable and efficient tool which expands the treatment options for many patients.
Case studies

Essential Tremor
Bilateral thalamotomy with Leksell Gamma Knife for Essential Tremor
The outcome after the two treatments was 100% improvement in both hands

Essential Tremor
Leksell Gamma Knife® radiosurgery for medically refractory essential tremor
Gamma Knife radiosurgery allows us to treat older and more fragile patients (av. age 78 years) or patients with co-morbidity who are not suitable for surgery.

Trigeminal Neuralgia
Leksell Gamma Knife® radiosurgery for trigeminal neuralgia associated with multiple sclerosis
In this case, a 39-year-old male patient with a history of multiple sclerosis had experienced right-side facial pain for two years. Seventeen months after treatment, the patient’s quality of life is significantly improved.

With Karolinska Hospital, Sweden, about the imaging and treatment planning benefits of Leksell Vantage for Gamma Knife
Learn why
Queen Square National Hospital decided to use Vantage for Gamma Knife
The targeting accuracy of the Vantage frame is sub-millimeter, which gave us the confidence to proceed to clinical implementation of the frame for Gamma Knife treatments.
