Systematic review of physical and dosimetric criteria for managing CIEDs in radiotherapy: A medical physicist's perspective

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Aim Current radiotherapy (RT) guidelines for Cardiac Implantable Electronic Devices (CIEDs) are largely based on clinical management strategies and retrospective reports. This systematic review adopts a medical physics perspective to provide a critical, quantitative analysis of the technical evidence required for developing robust safety ...

The effect of respiratory motion on electronic portal imaging device dosimetry [PDF]

Journal of Applied Clinical Medical Physics, 2019
AbstractThere is an increasing need to develop methods for in vivo verification of the delivery of radiotherapy treatments. Electronic portal imaging devices (EPID's) have been demonstrated to be of use for this application. The basic principle is relatively straightforward, the EPID is used to measure a two‐dimensional (2D) planar exit or portal dose ...

Implementation and validation of a commercial portal dosimetry software for intensity-modulated radiation therapy pre-treatment verification

Journal of Medical Physics, 2010
Electronic portal imaging devices (EPIDs) are extensively used for obtaining dosimetric information of pre-treatment field verification and in-vivo dosimetry for intensity-modulated radiotherapy (IMRT). In the present study, we have implemented the newly

Biomaterial‐Integrated Electroporation for Therapeutic Delivery: From Gene Editing to Tumor Ablation and Immune Modulation

Small, Volume 22, Issue 45, 13 August 2026.
Biomaterial‐integrated electroporation establishes a programmable therapeutic interface that coordinates electric‐field modulation, transient or irreversible membrane permeabilization, cargo stabilization, and immune remodeling. This Review highlights how nanocarriers, hydrogels, and bioelectronic interfaces expand electroporation from conventional ...

A Review of the Australian MRI Linac Program: From Pie in the Sky to Research Milestone

Journal of Medical Imaging and Radiation Oncology, Volume 70, Issue 5, Page 477-486, August 2026.
ABSTRACT The Australian Magnetic Resonance Imaging (MRI) Linear Accelerator program (MRI linac) was a major research project that aimed to build and test a unique MRI linac prototype for cancer treatment. It aimed to improve radiotherapy anatomical targeting and explore physiological targeting. The purpose of this report is to summarise the development

Dual‐scan conformal cone‐beam CT for targeted image‐quality improvement using dynamic collimation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is routinely used for image guidance in radiation therapy, but conventional full‐field CBCT acquisition may expose anatomically irrelevant regions and generate substantial scatter, which degrades soft‐tissue contrast and limits the accuracy of target localization and adaptive radiotherapy ...
