To validate an online adaptive radiotherapy (oART) workflow for a C-arm linear accelerator (LINAC) equipped with HyperSight CBCT using Imaging and Radiation Oncology Core (IROC) anthropomorphic phantoms.
To compare and evaluate the benefit of having dual activity on LDR prostate implants as opposed to one single activity to either decrease dose in organs at risks (OARs) urethra and rectum or increase dose to inaccessible areas as...
This study aimed to evaluate the clinical feasibility of a dual-target 3D-motion tracking workflow for 0.35T MRI-guided stereotactic body radiotherapy (MRgRT) in upper abdominal targets. The focus was on implementing real-time, d...
Gravity exerts a force on the X1 causing gantry flexion, albeit small, that can be minimized to improve targeting accuracy while it is rotating. This study sought to demonstrate the mitigation of gravity-induced effects by improv...
Three-dimensional multi-organ segmentation is a critical step in preclinical micro-CT imaging for quantitative analysis and reproducibility of longitudinal studies. However, manual delineation remains time-consuming and prone to...
Adjuvant radiotherapy following breast-conserving surgery or mastectomy reduces recurrence and improves survival of breast cancer patients. Left-sided breast radiotherapy, however, increases the risk of radiation-induced heart to...
Occupational exposure during Lutetium-177 (Lu-177) radiopharmaceutical therapy depends on administration technique, shielding configuration, and staff proximity—temporal and spatial. This study quantified extremity and whole-body...
Target coverage in lung SBRT is influenced by tumor size, PTV margin, and local lung density. This study investigates target dose coverage in low‑density lung as a function of PTV margins and lung density.
Total Body Irradiation (TBI) is a crucial component prior to bone marrow transplantation. A beam spoiler is typically used to increase the dose in the high-energy X-ray buildup region to 90% of prescribed dose. This is the first...
Intravenous (IV) and oral contrast are often utilized during the CT simulation for radiation planning. Overriding contrast prior to planning and dose calculations is often a part of standard workflow. This project investigates th...
One-dimensional (1D) water tanks are widely used in clinical practice due to their efficiency and reduced setup complexity; however, measurement accuracy can be influenced by operational parameters selected during data acquisitio...
Aluminum (Al, 2.7 g/cc) can be used with internal lead shielding to reduce backscattered dose to superficial targets, particularly in superficial lip cancers. Cutting and molding an Al sheet to comfortably fit inside the mouth of...
FLASH radiotherapy (FLASH-RT), utilizing ultra-high dose rates (UHDR), orders of magnitude above those of conventional RT, is unique by its significantly reduced damage to healthy tissues (sparing effect) that do not compromise t...
To establish baseline Electronic Portal Imaging Device (EPID) data for validating dosimetric equivalence across a fleet of Varian TrueBeam linear accelerators. The primary objective was to reduce the inter-user and setup variabil...
DynamicARC is a pencil beam scanning (PBS) proton therapy technique designed to improve delivery efficiency and plan quality. This study evaluated how energy layer spacing (ELS) affects target coverage, dose homogeneity, and orga...
Electron beam therapy is widely used for the treatment of superficial tumors; however, low-energy electron beams typically deliver a surface dose that is 20% lower than the maximum dose. Although the application of a bolus can in...
Radiation therapy is a critical modality in cancer treatment, relying on medical Linear Accelerators (LINACs) to deliver precise radiation doses while minimizing exposure to surrounding healthy tissues. LINAC systems generate ext...
The proposed multimodal segmentation framework, named EPIDSeg-Net, comprises an encoder, a multi-scale feature layer, and a decoder. The encoder utilizes a dual-branch architecture: a CNN branch for extracting local texture featu...
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 develop and validate a methodology for assessing SRT patient transferability from an HD MLC LINAC with the BrianLab treatment planning system (TPS) to a standard Millenium MLC (SM MLC) LINAC planned with Eclipse TPS, with the...
To quantify the geometric accuracy of an automatic applicator anchor point placement framework for cervical cancer (CC) high-dose-rate (HDR) brachytherapy implemented in Oncentra Brachy (Elekta).
Prostate cancer is the most common form of cancer, excluding skin cancer, and results in significant genitourinary toxicity. Rectal gas buildup has exacerbated this by changing simulated patient anatomy and introducing tissue inh...
This study evaluates a beryllium oxide (BeO)–based optically stimulated luminescent (OSL) dosimetry system (myOSL, RadPro Int. GmbH) for clinical radiotherapy applications.
