Gamma Knife Radiosurgery

What is the Gamma Knife?

Gamma Knife is a state-of-the-art, non-invasive neurosurgical technology that has redefined the landscape of brain treatment. Unlike traditional surgical methods, Gamma Knife does not require any incision, providing a highly precise and targeted approach to address various neurological conditions.

The system utilises a multitude of highly focused gamma-ray beams to converge at a specific point within the brain. This convergence is exceptionally precise, allowing for the treatment of intricate brain conditions without affecting the surrounding healthy tissue.



Gamma Knife is a proven technology and is considered the gold standard for brain radiosurgery.


Why Gamma Knife?

1: Precision: Gamma Knife Esprit ensures sub-millimeter accuracy, targeting specific areas with minimal impact on surrounding healthy tissue. 

2: Single Session Treatment: Gamma Knife treatment is completed in a single session that allows swift recovery. 

3: Non-Invasive Surgery: There is no need for any incision, which reduces the risk of complication. 

4: Versatility in Action: Gamma Knife serves as a versatile solution for a spectrum of neurosurgical needs such as benign and malignant tumours, vascular malformations, and functional disorders.



Outcomes of Gamma Knife Treatment:

1: Unmatched Tumour Control: Gamma Knife can achieve unmatched tumour control and halts tumour growth effectively. 

2: Safe and Accurate Treatment: Due to its high precision, Gamma Knife radiosurgery is a safe and accurate treatment option. 

3: Improvement in Quality of Life: Personalised treatment plans enhance overall well-being, and result in improved quality of life.

  • Is a Gamma Knife suitable for all brain conditions?

    Gamma Knife is highly versatile, addressing various conditions such as tumors, trigeminal neuralgia, and arteriovenous malformations.

  • How long does a Gamma Knife procedure take?

    While treatment duration varies, the actual radiation delivery is typically completed in a single session and takes few minutes.

  • What is the recovery time after Gamma Knife treatment?

    Recovery is generally swift, with many patients resuming normal activities the next day.

  • Is Gamma Knife safe?

    Yes, Gamma Knife is a proven and gold standard technology with minimal side effects, owing to its precise targeting.

  • Is Gamma Knife effective for multiple brain metastasis?

    For multiple brain metastasis patients usually undergo whole brain radiation under conventional LINAC that can cause damage to normal brain tissues whereas, Gamma Knife is highly precise and hence, adjacent tissues remain safe. Also, multiple brain metastasis can be treated by Gamma Knife in a single session. Even in LINAC based radiosurgery it’s difficult to treat more than 4 metastasis.

  • Can Gamma Knife treatment be given more than once?

    Yes, Gamma Knife can be repeated multiple times either for the same tumor if required or for another metastasis which may come up later. Because of its precision, there is minimal radiation surrounding normal tissue and hence repeat treatments are not only possible but safe as compared to other technologies.
