Ultrasound-guided high-dose-rate (HDR) interstitial prostate brachytherapy is a technically demanding procedure requiring proficiency in imaging, catheter reconstruction, contouring, treatment planning, and quality assurance unde...

High-dose-rate (HDR) brachytherapy (BT) is characterised by steep dose gradients and high doses delivered per treatment fraction in a short time. These features, together with the numerous steps involved in treatment delivery, ma...

To share our experience with the acceptance testing of nine myQA Daily devices (IBA) and to evaluate the relevance of these tests despite the system being widely used clinically in other hospitals.

To assess different proton beam arrangements’ robustness for planning stereotactic body proton therapy (SBPT) to the liver.

The primary objective of this study was to develop and validate a machine learning (ML) model to predict gamma pass rates (GPR) for patient-specific quality assurance (PSQA), with the ultimate goal of advancing this model into an...

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...

Modern linear accelerators maintain precise control of delivery parameters during the treatment of dynamic external beam radiotherapy treatment plans; vendors provide snapshots of these parameters using trajectory log files (TLF)...

To develop and evaluate an automated, log-file–based MLC positional accuracy QA method for routine and longitudinal assessment of MLC performance on the ViewRay MRIdian MR-Linac system.

To clinically validate log file–based patient-specific quality assurance (PSQA) for IMRT and VMAT treatments as an efficient alternative to physical measurement-based methods, while maintaining compliance with AAPM recommendation...

Open-source software offers a transparent and cost-effective alternative to commercial, patient-specific quality assurance (PSQA) systems; however, clinical validation remains essential. This study aims to validate open-source Py...

To commission the SRS MapCHECK detector for patient-specific quality assurance (PSQA) of CyberKnife multileaf collimator (MLC) treatment plans and to evaluate its clinical performance across multiple disease sites using stringent...

To evaluate patient-specific quality assurance (PSQA) measurements across 18 disease sites treated with intensity modulated proton therapy (IMPT) from January 2024 through August 2025.

Setup variability in routine linear accelerator quality assurance (QA), such as daily and monthly output checks, can introduce undesirable measurement uncertainty and reduce the accuracy of QA testing. This work aims to design an...

To establish standardized, probe-specific depth of penetration baselines for protocol-specific clinical use across ultrasound transducers to support routine quality assurance (QA), enable early detection of probe degradation, and...

To establish the local diagnostic reference levels (LDRL) for low-dose CT (LDCT) using an automated dose management system and to evaluate the relative impacts of gender and body weight on radiation dose.

To compare the traditional Computed Tomography Dose Index (CTDI) and the Cone-Beam-Dose-Index (CBDI), an alternative metric that quantifies the average dose in the central region of a cone-beam CT (CBCT) scan, for imaging dose me...

To evaluate the suitability of the RTI Dose Probe for monitoring daily output constancy of SXRT machines.

This study evaluates the feasibility of an in-house Python script for analysis of routine quality assurance (QA) procedures that utilize an electronic portal imaging device (EPID) as a low-cost, efficient QA option compared to co...

To assess the long-term reliability of in-air film dosimetry approach for quality assurance (QA) of Cs-137 blood irradiators using the measured data accumulated over 5 years.

Routine imaging QA is critical for ensuring precise HDR prostate brachytherapy delivery. This study sought to verify the accuracy of the ultrasound imaging system and to identify potential improvements in quality-control processe...

HyperArc is an automated planning and delivery technique for single and multiple-target stereotactic radiosurgery (SRS) treatments that creates highly conformal plans and has potential for saving time. This study evaluates whethe...

To investigate the difference in gamma passing rate and dose profile of measurement of patient specific quality assurance (PSQA) of SBRT plans using the SNC ArcCHECK in single measurement and high-density diode merge measurement.

Increased use of portal imaging for quality assurance of SRS/SBRT plans results in a higher workload for the center detector elements compared to the peripheral elements. This study aims to evaluate the long-term stability of the...

To compare two patient-specific quality assurance measurements for trigeminal neuralgia (TN) treatments to ensure that the QA delivery matches the mechanical treatment limitations.
