Radiation-induced lymphopenia (RiL) worsens survival in glioblastoma by impairing anti-tumor immunity. Reducing dose to circulating lymphocytes (CLs) may help mitigate RiL. Because IMRT and VMAT differ in their dynamic delivery t...

To validate and deploy a complete applicator-specific phase space file library for the GMV Radiance treatment planning system, establishing the first clinically ready Monte Carlo-based treatment planning system (TPS) for electron...

Dose-optimized proton pencil beam scanning (PBS) treatments that are collimated using the Dynamic Collimation System (DCS) have greater dosimetric sparing of healthy tissue compared to uncollimated treatment plans, but difference...

Previous work suggests that automatically optimized plans were dosimetrically non-inferior to manual, interactively optimized plans based on institutional clinical goals in a retrospective paired analysis. This study aimed to ext...

Photodynamic therapy and photothermal therapy commonly rely on tetrapyrrole based photosensitizers, whose therapeutic efficacy is governed by their electronic absorption property in the visible and near infrared regions. Accurate...

Automatic treatment planning and physician’s plan preference quantification are both critical tasks in High-dose-rate brachytherapy (HDRBT) of cervical cancer for rapidly generating high-quality plans meeting physician’s intent....

PEG dependence is widely considered a consequence of head and neck re-irradiation (HN re-RT), yet PEG persistence around treatment is frequently misinterpreted as durable swallowing toxicity. We introduce a time-anchored definiti...

Brain metastases (BM) can be treated with linear accelerator (LINAC)-based stereotactic radiosurgery (SRS). Treatment planning for this modality has evolved over time; plans typically have one, two, or n isocenters, where n is th...

To develop and evaluate a structure-guided multi-task deep learning framework for synthesizing positron emission tomography (PET) images from computed tomography (CT) in patients with esophageal cancer, aiming to improve both glo...

To design and fabricate a 3D-printed anthropomorphic phantom of the lumbar spine and pelvis to evaluate and improve the quantitative accuracy of SPECT/CT imaging and dosimetry for bone marrow and vertebral body lesions.

Traditional reliability analyses of linear accelerators (LINACs) have typically focused on individual components using limited datasets, failing to exploit the comprehensive operational insights contained within service logs. Thi...

Extranodal extension (ECE) of metastatic lymph nodes is a major adverse prognostic factor in head and neck cancer and strongly influences treatment intensity. However, pre-operative identification of ECE on CT is challenging, sub...

To evaluate the reasoning capabilities of large language models (LLMs) in performing root cause analysis (RCA) of radiation oncology incidents using narrative reports from the Radiation Oncology Incident Learning System (RO-ILS),...

Redistribution of radioactive daughters following ²²⁵Ac decay is a major dose-limiting uncertainty in α-emitter radiopharmaceutical therapy (αRPT). Free daughter species may diffuse from their site of origin, yet their microscale...

To propose a Graph Neural Network (GNN) framework that explicitly models liver vessel topology to detect anatomical landmarks and reconstruct anatomically consistent segments.

A clear link has been established between exposure to neutron-producing therapies and cardiac implantable electronic device (CIED) malfunction. However, the risk of neutron-induced CIED malfunction under specific clinical conditi...
