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...

Contrast-enhanced single-energy CT (SECT) scans provide superior image contrast and better differentiation of the target volume and vascular structures compared to non-contrast CT scans at the cost of deteriorated dose calculatio...

To investigate whether the apparent diffusion coefficient (ADC) from diffusion-weighted imaging (DWI) acquired at a 0.35T MR-Linac can determine prostate and intraprostatic lesion changes caused by adaptive radiotherapy performed...

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...

CyberKnife stereotactic treatments are delivered using a step-and-shoot technique, with patient-specific QA verification plans for diode array measurements typically generated and evaluated in a perpendicular composite geometry....

MR-linacs enable online adaptive radiotherapy, which increases dose conformality and thus potentially improves therapeutic ratios. A recurring drawback with respect to C-arm linacs is the lack of VMAT leading to decreased efficie...

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...

Ring applicators are widely used in high-dose-rate (HDR) brachytherapy, where accurate source positioning is essential for achieving dosimetric precision. Following each radioactive source exchange, positional accuracy is routine...

Radiomics features are increasingly used for quantitative image analysis; however, their robustness to image acquisition and reconstruction parameters remains a critical concern. Field of view (FOV) variations can alter image sam...

To assess the effectiveness of SVD-based denoising on the brain Diffusion Weighted images acquired from a 0.35T ViewRay Magnetic Resonance Linac (MRL) and enhance the image quality while preserving the diffusion information.

In proton radiotherapy, layer switching time constitutes the most time-consuming procedure. By rationally reducing the total energy layers, treatment efficiency can be enhanced without compromising dose distribution or dosimetric...

To develop and evaluate a treatment planning method for the Venezia HDR applicator that utilizes interstitial needles to enhance High Risk Clinical Target Volume (HRCTV) coverage and reduce dose to organs at risk (OARs) through a...

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)...

Cone-beam CT (CBCT) is routinely used for image-guided radiation therapy (IGRT); however, in the optimal frequency of CBCT varies across patients and treatment sites, affecting imaging dose, workflow efficiency, and clinical cons...

To address the labor-intensive nature of Deformable Image Registration (DIR) QA quantitatively through the use of independent software and in-house scripting for lung and Head & Neck (H&N) sites for clinical use.

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.

Automated treatment planning can reduce manual workload and improve consistency; however, supporting new clinical indications often requires development of dedicated tools rather than reuse of existing workflows. This study descr...

Initial plan/chart review requires significant effort and can be labor-intensive, time-consuming, and error-prone. This is particularly challenging when working with non-integrated systems, such as the RayStation treatment planni...

Automating post-operative primary clinical target volume (CTV) segmentation in head and neck (H&N) cancers is challenging due to the surgical absence of the primary tumor and anatomical heterogeneity. Without the distinct radiogr...

This study investigates a model for the auto-segmentation of cranial nerves in the context of radiosurgery treatment planning for acoustic neuroma and trigeminal neuralgia. Current treatment planning systems are unable to perform...

Resin Yttrium-90 (Y-90) selective internal radiation therapy (SIRT) is a radioembolization procedure that uses Y-90 microspheres to treat metastatic liver cancer. In the procedure, liver volume and tumor volume are needed for Y-9...

As HDR Brachytherapy has the potential to increase in popularity due to changes in reimbursement models, the potential of new treatment sites for the modality can be increased through increased oargan-at-risk sparing via integrat...
