To demonstrate feasibility of three-dimensional ultrasound (3DUS) for the detection of oral squamous cell carcinoma (OSCC) and to evaluate its potential as a pre-clinical screening tool.

The 0.55T MRI offers potential advantages including reduced susceptibility artifacts and improved accessibility. Separately, HyperSight cone-beam CT on the Ethos enables direct dose calculation during adaptive radiotherapy. This...

When cervical cancer patients with a hip prosthesis undergo standard-CBCT imaging, metal artifacts are present in the image due to the prosthesis high-Z material, leading to potential uncertainty in setup or contouring/dose calcu...

To examine whether new recently reported dose volume constraints of bladder and rectum can be satisfied in clinical prostate CyberKnife SBRTs without sacrificing target coverage. Also, to use a normal tissue complication (NTCP) m...

Proton pencil beam scanning (PBS) offers excellent dose conformity but remains limited by delivery inefficiency associated with energy layer switching time. A programmable energy modulation filter (PEMF) was developed to enable s...

In order to initiate a quality control (QC) process for clinical photon-counting computed tomography (PCCT), this work evaluates the applicability of AAPM Task Group Report 299 (TG299) for multi-energy CT (MECT) systems to PCCT,...

To assess the feasibility and dosimetric performance of volumetric-modulated arc therapy (VMAT) for total body irradiation (TBI) using high-resolution multileaf collimators (HR-MLCs).

This study assessed the feasibility and dosimetric quality of uTPS (Shanghai United Imaging Healthcare, version R001) for left-sided breast cancer VMAT planning on dual-layer MLC Accelerators

While Optically Stimulated Luminescent Dosimeters (OSLDs) are widely used in clinical radiotherapy, their utility is typically limited to an accumulated dose of 10 Gy due to the filling of deep electron traps that causes sensitiv...

In an MRI-only simulation workflow, synthetic CT (sCT) are created from MR images and mimic the CT in terms of HU quality and geometric accuracy, therefore enabling dose calculation and patient setup verification. The elimination...

To evaluate sensitive organ and fetal doses for women undergoing mammography exams to determine potential risk and any justification for shielding.

To report clinical experience in commissioning Valencia surface applicators by applying published guidance and using fully film-based methods to assess source positioning, flatness/symmetry, depth dose, and output verification.

Magnetic resonance-guided radiotherapy (MRgRT) with a 1.5 T MR-Linac enables real-time tumor tracking but poses unique challenges for lung targets near the heart, where cardiac and respiratory motion coexist. This study reports t...

The upcoming AAPM Task Group 350 (TG-350) report proposes a standardized end-to-end test suite for commissioning proton pencil-beam scanning (PBS) systems. This work presents the first complete implementation of all eight TG-350...

FLASH radiotherapy (>40 Gy/s) demonstrates normal tissue sparing while maintaining tumor control, but pulse width variations systematically alter electron beam energy through waveguide loading effects, creating treatment planning...

To determine which cardiac substructures are associated with radiation-induced cardiac symptoms following radiotherapy for stage III non-small cell lung cancer (NSCLC), and to estimate the corresponding dose–response relationship...

Magnetic resonance (MR)–only radiotherapy planning requires accurate synthetic CT (sCT) generation from images acquired using standard clinical MRI simulation protocols. However, MRI acquisition protocols vary substantially acros...

Foundation models are general-purpose, adaptable deep learning models trained on vast amounts of data. Despite unprecedented performance in language and vision tasks, their utility for predicting patient outcomes remains to be ex...

To address the data scarcity bottleneck in deep learning (DL) dose prediction by establishing a foundation model-based transfer learning framework. We aim to demonstrate that adapting large-scale public priors to institutional da...

Pulmonary fluid changes often necessitate treatment replanning; however, associated mass variations compromise deformable dose accumulation (DDA) and complicate its evaluation. Accurate estimation of cumulative dose and its assoc...

High-dose-rate (HDR) tandem and ring cervical brachytherapy requires significant time and resources from implant, to imaging, planning, and treatment. The high-risk clinical target volume (HR-CTV) and organs at risk (OARs) are co...

While 30% of lung cancer patients cannot tolerate breath-hold, free-breathing(FB) proton pencil-beam-scanning(PBS) deliveries compromise target coverage from the interplay effects of large motion. This study presents a novel FB-g...

To develop and evaluate a convolutional neural network (CNN) framework that estimates portal dosimetry gamma passing rate (GPR) directly from predicted dose plane images, enabling rapid quality assurance (QA) decision support for...

A robust and routine quality assurance (QA) program for multileaf collimators (MLCs) is essential for accurate external beam radiotherapy delivery. Since the initial implementation of MLC-equipped linear accelerators (LINACs) at...
