Journal of Physics: Conference Series, 2017 Metastases of the spinal column are common amongst cancer patients with approximately 18,000 new cases in North America each year that require urgent treatment. Historically radiation therapy doses have been limited due to the proximity of the spinal cord.

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 ...

Journal of Medical Radiation Sciences, EarlyView.This prospective study investigated the feasibility of stabilised hyaluronic acid gel as a rectal spacer in gynaecological cancer brachytherapy. In twelve patients, the spacer was successfully inserted into the rectovaginal space without serious adverse events, had high visibility on MRI, increased the target‐to‐rectum distance compared with no spacer ...

Radiation Therapy Medical Physics Review – Delivery, Interactions, Safety, Feasibility, and Head to Head Comparisons of the Leading Radiation Therapy Techniques [PDF]
, 2017 Radiation therapy uses high energy radiation to kill cancer cells. Radiation therapy for cancer treatment can take the form of photon therapy (using x-rays and gamma rays), or charged particle therapy including proton therapy and electron therapy. Within

Dosimetric advantage of volumetric modulated arc therapy in the treatment of intraocular cancer
Radiation Oncology, 2017 Objective The purpose of this study is to investigate the dosimetric advantages of volumetric modulated arc therapy (VMAT) in the treatment of intraocular cancer by comparing it directly with three-dimensional conformal radiotherapy (CRT) and intensity ...

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...
