Reproducibility and geometric accuracy of the fixster system during hypofractionated stereotactic radiotherapy

Radiation Oncology, 2008
Background Hypofractionated radiotherapy has been used for the treatment of AVMs and brain metastases. Hypofractionation necessitates the use of a relocatable stereotactic frame that has to be applied on several occasions. The stereotactic frame needs to

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Stereotactic Irradiation of GH-Secreting Pituitary Adenomas

International Journal of Endocrinology, 2012
Radiotherapy (RT) is often employed in patients with acromegaly refractory to medical and/or surgical interventions in order to prevent tumour regrowth and normalize elevated GH and IGF-I levels. It achieves tumour control and hormone normalization up to

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Is Proton Therapy Superior to Gamma Knife Radiosurgery for Sporadic Vestibular Schwannoma?

The Laryngoscope, EarlyView.
With changing practice patterns, radiation therapy for vestibular schwannomas has become an increasingly utilized treatment modality with high tumor control rates. Gamma‐Knife radiosurgery remains a well‐established and readily accessible option with good rates for tumor control, cranial nerve preservation, and hearing outcomes.

CyberKnife Stereotactic Radiosurgery System for Pituitary Tumors and Pulmonary Cancer Bone Metastases: Initiating a New Chapter in Stereotactic Radiotherapy

Xiehe Yixue Zazhi
The CyberKnife, an acronym for the stereotactic radiosurgery platform, represents an image-guided stereotactic radiotherapy technique. This technology precisely delivers ionizing radiation to tissues, effectively damaging tumor cells, and is suitable for
