Volume staging for arteriovenous malformation SRS treatment using VMAT
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Volume staging involves dividing the target volume into smaller parts and treating each part separately. In this study, the feasibility of volume‐staged stereotactic radiosurgery (VS‐SRS) on a linear accelerator using volumetric modulated arc therapy (VMAT) and a frameless patient positioning system is investigated.

Radiotherapy and radiosurgery for meningiomas [PDF]
Neuro-Oncology Advances, 2023 AbstractMeningiomas comprise a histologically and clinically diverse set of tumors arising from the meningothelial lining of the central nervous system. In the past decade, remarkable progress has been made in deciphering the biology of these common neoplasms.

Cancer Medicine, Volume 11, Issue 24, Page 4806-4815, December 2022., 2022 Over 65% and over 90% volume reduction of brain metastases at 6 months post‐SRT predicts good local control. Beneficial volume reduction may require increasing the dose to GTV D80 in the LQ model: α/β = 20, and inhomogeneous dose distribution may be required for SRT for brain metastases.

Analysis Of Radiation Dose Distribution Inhomogenity Effects In Gamma Knife Radiosurgery Using Geant4 [PDF]
, 2021 The Monte Carlo method is widely used in the Gamma Knife dose distribution calculations. In this study, Monte-Carlo simulation with Geant4 was applied to determine Leksell Gamma Knife dose distribution for homogeneous solid water and heterogeneous brain phantoms, and primarily focused on the differences arising from the effects of inhomogeneity.

Low‐field MRI: Clinical promise and challenges
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023 Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

Pencil‐beam scanning proton therapy for the treatment of glomus jugulare tumours
Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 456-462, December 2022., 2022 The rare locally destructive glomus jugulare tumours could be treated using pencil‐beam scanning proton therapy (an alternative to surgery). Proton therapy provides good local control and acceptable toxicity. This paper reports treatment outcomes, acute and early late toxicities of 12 patients with glomus jugulare tumours.
