A review on radiochromic film dosimetry in radiation therapy
Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.Abstract Radiochromic films (RCFs) are ubiquitous in radiation oncology clinical and research settings to measure the radiation dose over a two‐dimensional (2D) area due to their high spatial resolution, water‐equivalency, and relative ease‐of‐use. Upon irradiation, the constituent monomers of the active layer of RCFs undergo polymerization, leading to

Dosimetry with a fluoroscopic electronic portal imaging device [PDF]
Medical Physics, 2000 Techniques for dosimetric verification of radiotherapy treatments using a CCD camera based fluoroscopic electronic portal imaging device (EPID) are described. The dosimetric characteristics of the EPID were investigated and a method was developed to derive portal dose images (PDIs) from measured EPID images.

Feasibility of treatment planning with HyperArc stereotactic radiosurgery methods for ocular tumors
Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.Abstract Purpose/objectives Currently, ocular disease is primarily managed with COMS plaque brachytherapy. Various stereotactic radiosurgery (SRS) platforms have also been employed, yet widespread access remains a challenge. Herein, we demonstrate the feasibility of using the HyperArc SRS system to provide an additional platform for the treatment of ...

Development of a linear array for intracavitary in vivo dosimetry during external beam radiotherapy and brachytherapy. [PDF]
, 2003 We present the details of a new linear array dosimeter consisting of a chain of semiconductors mounted on an ultra-thin (50 μm thick) flexible substrate and housed in an intracavitary catheter. The semiconductors, manufactured by NMRC Cork, have not been

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.Abstract Background Brain metastases (BMs), among the most prevalent intracranial malignant tumors, frequently induce acute symptoms such as headaches and motor deficits due to elevated intracranial pressure. Although hippocampal‐avoidance whole brain radiotherapy (HA‐WBRT) has demonstrated superior preservation of cognitive function compared to ...
