Cherenkov imaging offers real-time visualization and verification of external beam delivery during radiation therapy. However, the relationship between beam parameters and Cherenkov photon yield per unit dose remains underexplore...

Investigate the association between neurocognitive function (NCF) and functional connectomics derived from commonly used group-level brain parcellations on patients with brain tumors.

To investigate infrared (IR) marker-based tracking for holographic patient alignment in radiation therapy and to establish quality assurance (QA) methods for the technique.

Lung nodule distribution is non-homogeneous, yet localized risk factors are poorly understood. This study aims to develop a computational pipeline to construct a 3D lung atlas, identifying population-level spatial trends to guide...

To experimentally characterize low-energy helium-4 (⁴He⁺) ion beams at subclinical energies (0.5–1.5 MeV/u) at the newly commissioned ASPIRE facility at TRIUMF using radiochromic film dosimetry, and to validate the measured dose...

To evaluate a new slot scanning technology (True2Scale (T2S), Multitom Rax, Siemens Healthcare, Germany) and compare it with conventional EOS biplane slot scanning (EOS Imaging, France) for scoliosis examinations via phantom and...

Secondary radiation from proton therapy can induce activation in beamline components, range shifters, and phantoms/patients. Rapid identification and localization of activated regions are critical for radiation safety, compliance...

To share our initial clinical experience using the Siemens MAGNETOM Free.Max low field strength (0.55T) scanner for gynecological brachytherapy, including establishing sequences, assessing geometric distortion for a titanium tand...

Radiotherapy quality assurance (RTQA) of target volume delineation is critical in clinical trials to ensure protocol adherence. Manual real-time review is resource-intensive and often limited to a subset of patients. This study e...

Measurement-based patient-specific QA is often impractical in adaptive workflows, motivating the use of complexity metrics. For tumor-site-specific class solutions [NCS 35], consistent beam characteristics allow the definition of...

Ultrasound imaging is often used for therapy guidance, including focused ultrasound procedures. There is often a discrepancy between the designs of focused ultrasound source and diagnostic imaging probes, and target visualization...

The increased attention on radiation risks and dose reduction in CT imaging presents opportunities for the presentation and discussion of institutional dose trends and factors contributing to change. The objective of this work is...

The 2018 EMBRACE II study emphasizes minimizing vaginal mucosal dose during locally advanced cervical cancer brachytherapy. While traditional organs at risk include bladder, rectum, and sigmoid, vaginal mucosa dose has gained att...

Quality assurance (QA) testing of multichannel phased-array RF coils on modern MRI scanners frequently produces images with very low background noise. While prior work has addressed bias arising from magnitude reconstruction and...

Online adaptive prostate MR-guided radiotherapy (MRgRT) is time-sensitive, and contouring with structure preparation can require upwards of 15 minutes per fraction. While vendor-TPS provided contours can be useful, performance an...

Radiation pneumonitis (RP) is a dose-limiting toxicity following thoracic radiotherapy. Existing RP prediction models have largely focused on clinical factors and conventional dose-volume histogram (DVH) metrics, with limited con...

Stereotactic ablative radiotherapy (SAbR) achieves high local control in patients with oligometastatic renal cell carcinoma (omRCC), but a subset of patients experience early progression due to occult micrometastatic disease and...

This study characterizes the spatial heterogeneity of non-small cell lung cancer (NSCLC) using intratumoral habitat radiomics and explores its predictive capability for overall survival in radiotherapy-treated patients by integra...

Survival prediction based on radiomics and deep learning may aid treatment decision-making and follow-up management. This study aims to develop and validate an integrated model integrating multimodal imaging (MRI and CT), radiomi...

To overcome barriers in Intensity-Modulated Radiation Therapy (IMRT) research caused by reliance on proprietary optimization solvers (e.g., CPLEX) and fragmented software environments. We present the integration of a voxel down-s...

Hyperpolarized Xenon imaging is a recent FDA-approved MRI technique that can measure physiological changes in ventilation, membrane uptake, and red blood cell transfer of gas throughout the lung. The scope of this work is to demo...

There are many recent advances in linear energy transfer (LET) optimized proton therapy planning, radiation biology, immune therapy, and molecular imaging with the potential to improve the efficacy of radiation oncology. The aim...

Evidence suggests a competing dynamic for radiation therapy (RT) and immunological response to tumors; while radiation-induced immune suppression (RIIS) inhibits immune processes, which may result in lower tumor control and survi...

This work focuses on implementing a GPU-accelerated multi-criteria optimization (MCO) framework for HDR brachytherapy, including advanced applicators such as Direction-Modulated Brachytherapy (DMBT), and developing a graphical us...
