Quality assurance of RapidArc in clinical practice using portal dosimetry [PDF]

The British Journal of Radiology, 2011
Quality assurance data from five centres were analysed to assess the reliability of RapidArc radiotherapy delivery in terms of machine and dosimetric performance.A large group of patients was treated with RapidArc radiotherapy and treatment data recorded. Machine quality assurance was performed according to Ling et al (Int J Radiat Oncol Biol Phys 2008;

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

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 ...

Effect of variations in atelectasis on tumor displacement during radiation therapy for locally advanced lung cancer [PDF]

, 2017
Purpose Atelectasis (AT), or collapsed lung, is frequently associated with central lung tumors. We investigated the variation of atelectasis volumes during radiation therapy and analyzed the effect of AT volume changes on the reproducibility of the ...

Concurrent ANNPE and vertebral T‐cell lymphoma in a dog: A case report

Journal of Small Animal Practice, EarlyView.
Acute non‐compressive nucleus pulposus extrusion (ANNPE) is a recognised cause of peracute spinal cord injury in dogs, involving sudden extrusion of non‐degenerated nucleus pulposus with minimal compression. While often linked to vigorous activity, its triggers remain unclear.

Clinical Efficacy of an Electronic Portal Imaging Device versus a Physical Phantom Tool for Patient-Specific Quality Assurance

Life, 2022
Pre-treatment patient-specific quality assurance (QA) is critical to prevent radiation accidents. The electronic portal imaging device (EPID) is a dose measurement tool with good resolution and a low volume-averaging effect.

Transit dosimetry of stereotactic body radiotherapy treatments with electronic portal dosimetry device in patient with spinal implant

Physical and Engineering Sciences in Medicine, 2022
Abstract Aim In recent years, the use of the Electronic Portal Imaging Device (EPID) as an in vivo dosimeter has become widespread. However, reports of EPID for stereotactic body radiotherapy (SBRT) applications is scarce. There is no data on this topic especially when there are high-density materials in the radiation field.

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...
