Shortages of trained medical physicists persist across Africa. Needs-assessment surveys were utilized to determine trainee interest and medical physics curricular gaps to aid in design of hands-on outreach workshops for the Afric...

We evaluate the performance of a 4-channel plastic scintillator for real-time dose monitoring during VMAT total body irradiations (TBI).

To compare dosimetry audit results for 6 MV flattening-filter-free (FFF) photon beams between conventional C-arm linear accelerators (linacs) and a ring-based architecture (O-ring) linacs using IAEA/WHO postal dosimetry audit res...

Post-therapy quantitative imaging is essential for dosimetry-guided precision cancer treatment in theranostics. Although SPECT is the typical choice for post-therapy quantification, its routine clinical use is constrained by scan...

To determine the feasibility of using a high temporal resolution electronic dosimeter (NetDose+, manufactured by ThermoScientific) for patient-specific pharmacokinetic data collection and analysis for the immediate post-administr...

To evaluate long-term calibration stability and measurement uncertainty in reference dosimetry systems through systematic intercomparison analysis, establishing evidence-based quality assurance recommendations for radiation oncol...

Dose–volume histograms (DVHs) are widely used in external beam radiation therapy, but their applicability to Y-90 transarterial radioembolization (TARE) remains uncertain. In Y-90 TARE, absorbed dose maps are derived from post-th...

Measurement based QA is required in clinical practice due to the delivery complexity of IMRT. Many factors can affect measurement accuracy and QA passing rate. In this study, we aimed to investigate the impact of beam hardening a...

Small animal irradiator radiation measurements for kV x-rays typically use in-air absolute dose rate calibration and film in solid water for planar dose distributions. Using water as a medium provides a close representation of so...

While optically stimulated luminescence dosimeters (OSLD) offer advantages in reusability and efficiency, they overestimate the surface dose due to thick effective point of measurement. The aim of this study is to investigate the...

As treatment planning evolves toward patient-specific optimization, traditional static dose constraints are insufficient for distinguishing high-quality versus acceptable plans. Current planning directives rely on generic dose co...

To commission and clinically implement a modified Stanford technique for Total Skin Electron Irradiation (TSEI) using a standard TrueBeam linac, achieving consistent and high-quality skin dose coverage.

Within the range 100 keV to 15 MeV and dose higher than 500cGy, GafChromic EBT3 films exhibits very weak energy dependent. However, EBT3 films are no longer produced. In this study, EBT4 GafChromic films were used for absolute do...

To perform comprehensive dosimetric validation of a commercially available independent Monte Carlo (MC)-based secondary dose calculation engine for clinical photon radiotherapy.

To establish a practical framework for implementing spatially fractionated radiation therapy (SFRT) in clinics without existing infrastructure by developing treatment planning workflows and identifying requirements for clinical a...

An educational endeavor has been initiated to provide the diagnostic radiology (DR) community with an up-to-date resource describing the physics and clinical implementation of DR imaging physics. The resource will be widely, and...

To develop a simple protocol for dose verification of Leipzig surface HDR applicators using Gafchromic EBT3 film.

Stereotactic radiosurgery (SRS) delivered with linear accelerators requires submillimetric mechanical, geometric, and dosimetric accuracy. Although postal and remote audit programs are widely available, they do not fully capture...

The goal of this study is to develop a simple treatment planning system (TPS) to assess the dosimetry of a Y-90 source train-based treatment for intravascular brachytherapy (IVBT) using data from Monte-Carlo simulations.

To develop and evaluate a clinically practical single-isocenter stereotactic radiosurgery (SRS) planning strategy for patients with multiple brain metastases in RayStation, with the goals of establishing institutional planning gu...

To determine the dosimetric impact of 3D-printed patient-specific cylindrical templates (PSCTs) printed with Formlabs Biomed Clear (BC) resin in gynecologic (GYN) high-dose-rate brachytherapy (HDRBT), and to validate clinical int...

Aluminum (Al, 2.7 g/cc) can be used with internal lead shielding to reduce backscattered dose to superficial targets, particularly in superficial lip cancers. Cutting and molding an Al sheet to comfortably fit inside the mouth of...

To establish baseline Electronic Portal Imaging Device (EPID) data for validating dosimetric equivalence across a fleet of Varian TrueBeam linear accelerators. The primary objective was to reduce the inter-user and setup variabil...

To develop and validate a methodology for assessing SRT patient transferability from an HD MLC LINAC with the BrianLab treatment planning system (TPS) to a standard Millenium MLC (SM MLC) LINAC planned with Eclipse TPS, with the...
