Absorbed doses for patients undergoing panoramic radiography, cephalometric radiography and CBCT

International Journal of Occupational Medicine and Environmental Health, 2017
Objectives: Contemporary dental radiology offers a wide spectrum of imaging methods but it also contributes to an increase in the participation of dental radiological diagnosis in the patient’s exposure to ionizing radiation.

Development of a Polydimethylsiloxane‐Based Flexible Digital Bolus Dosimeter: From Unit‐Cell Characterization to Linear Array for Skin‐Dose Distribution Verification

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
A flexible digital bolus dosimeter platform is proposed to address the challenges of surface‐dose monitoring. The study evaluates point‐dose performance using an IDE substrate and extends this to spatial dose distributions using an fPCB‐integrated 24‐pixel array.

Dose Measurements of Parotid Glands and Spinal Cord in Conventional Treatment of Nasopharyngeal Carcinoma Using RANDO Phantom and Thermoluminescent Dosimeters [PDF]

Iranian Journal of Medical Physics, 2015
Introduction Radiotherapy is regarded as the first treatment of choice for nasopharyngeal carcinoma. Despite the advantages of radiotherapy, patients may suffer from a wide range of side-effects due to the presence of many sensitive normal tissues in ...

Assessment of dose distribution in pancreatic SABR in the presence of a metallic biliary stent using Monte Carlo modeling

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Stereotactic ablative radiotherapy (SABR) with dose escalation is increasingly used for pancreatic cancer; however, the dosimetric impact of metallic biliary stents remains poorly characterized. Self‐expanding metal stents (SEMS), commonly placed for obstructive jaundice, contain high‐density nitinol that produces computed ...

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 ...

Lighting up FLASH and beyond: TLD response across four orders of magnitude in proton dose rate

Medical Physics, Volume 53, Issue 8, August 2026.
ABSTRACT Background Thermoluminescent dosimeters (TLDs) are widely used for proton therapy dosimetry and remote audits. Yet their response under pulsed delivery and the ultrahigh dose rates relevant to proton FLASH remains incompletely characterized.

Feasibility study: Use of an optical scanning system to obtain 3D body surface images suitable for total skin electron therapy treatment dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Total skin electron therapy (TSET, also known as TSE, TSI, TSEI or TSEBT) provides an effective treatment for extensive superficial lesions such as mycosis fungoides, although the standing setups and large distances used for treatment mean that comprehensive three‐dimensional (3D) dose calculations are rarely achievable clinically ...
