Total body irradiation (TBI) is a well-established conditioning regimen prior to hematopoietic stem cell transplant (HSCT) for treatment of leukemia cancers. This study reports on a Central-Asian national referral cancer centre’s...
Single-isocenter SBRT enables efficient treatment of multiple liver metastases but limits mitigation of rotational error. This study evaluates rotational uncertainty effects on target coverage in single-isocenter liver SBRT for p...
To develop a single-setup machine QA framework for multiple tests across different gantry angles in proton therapy. Current monthly QA procedures require separate setups to verify proton beam characteristics, including output con...
Small field sizes used in stereotactic radiosurgery (SRS) pose significant dosimetric challenges due to heightened sensitivity to detector size, geometry, and response in small-beam conditions. Accurate determination of small fie...
This work introduces a framework to automate treatment planning of small-volume lattice radiotherapy applied to head and neck malignancies.
Four-dimensional cone-beam computed tomography (4D-CBCT) enables visualization of respiration-induced anatomical motion but suffers from degraded image quality due to sparse-view acquisition. This study proposes a deep learning-b...
Spatially Fractionated Radiation therapy (SFRT) and brachytherapy both have high dose heterogeneity featuring localized high-dose regions and steep dose gradients. While SFRT techniques such as GRID and Lattice intentionally crea...
Within the Joint Research Project PRISM-eBT to establish primary standards and traceable measurement methods for electronic brachytherapy devices (eBT), three different devices were spectrometrically investigated: the “Intrabeam®...
Urgent clinical electron radiotherapy for postoperative treatments (e.g., keloid) is often performed without CT-based planning. In a large hospital network with multiple treatment locations, variability in electron data and workf...
The goal of this project is to standardize and automate the QA program of a multi-location radiation oncology practice. Our practice includes eleven linear accelerators, five CT scanners, and four HDR afterloaders, across four se...
High-density metallic ports in breast tissue expanders (TE) introduce CT artifacts that cause dose calculation uncertainties for postmastectomy radiation planning. TE ports have either a titanium or stainless-steel needle guard a...
To Standardize multi-leaf collimator (MLC) leaf-end dosimetry by adjusting the physical MLC gap across multiple linacs within an enterprise.
This talk describes our organization’s CT optimization program, and how we implemented it to make efficient use of limited physicist time.
Accurate precise planning and delivery of linac-based stereotactic radiosurgery (SRS) can be technically challenging and stressful. Thus, it is important to develop a streamlined clinical workflow to increase efficiency, accuracy...
To validate the Acuros XB dose calculation algorithm for lung Stereotactic Body Radiation Therapy (SBRT) by comparing it with the Anisotropic Analytical Algorithm (AAA) and Monte Carlo calculation, and to assess the influence of...
Plan deliverability robustness was explored by identifying and gating motion-sensitive control point sequences in single-target cranial VMAT plans. A dose-informed, control-point-specific motion tolerance was tested for its perfo...
To characterize how well voluntary breath hold during imaging reduces motion-induced artifacts in HyperSight cone-beam CT (CBCT) images that make it challenging to provide adaptive radiotherapy of moving targets in the lung on th...
Sparse detector arrays commonly used for patient-specific radiotherapy quality assurance (QA) cannot provide complete spatial dose distribution measurements, leading to uncertainties particularly in high-gradient dose regions.The...
In Syed interstitial gynecologic (GYN) brachytherapy, preplanning is often used to guide applicator placement and anticipate target coverage. However, the accuracy of preplan‑based contouring relative to treatment‑day planning re...
Cycle generative adversarial network (GAN) has a difficulty in maintaining the structural integrity in a synthesized image for complex organs and tissues. In this study, we proposed a CycleGAN including multi-scale blocks and att...
To evaluate and optimize segmentation pipeline configurations for head-and-neck organ segmentation to improve accuracy, robustness, and clinical applicability.
A partial breast irradiation (PBI) VMAT technique has been implemented at our center based on clinical trial evidence that showed reduced long-term toxicity when compared with whole breast irradiation. Our use case for PBI includ...
Dynamic collimation is emerging as a next-generation energy-specific collimating technology that can drastically improve the lateral and distal conformity of Pencil Beam Scanning (PBS) proton therapy. Current treatment delivery a...
GPUMCD, a GPU-accelerated Monte Carlo dose calculation algorithm, was recently released for clinical implementation in the Elekta One Treatment Planning System (v6.2.3, EOP) for c-arm Elekta linear accelerators (linac). The purpo...
