HyperArc is an automated planning and delivery technique for single and multiple-target stereotactic radiosurgery (SRS) treatments that creates highly conformal plans and has potential for saving time. This study evaluates whethe...
The purpose of this study is to evaluate image quality, effective dose, and projected cancer risk to patients during pediatric Contrast-Enhanced Computed Tomography (CECT) procedures.
Accurate patient positioning is critical in proton therapy, where range uncertainties increase sensitivity to setup errors; therefore, cone beam computed tomography (CBCT) is routinely used for image guidance. However, it also in...
To quantify the impact of daily MR-guided adaptive replanning for prostate SBRT on protocol dose-constraint fulfillment, compared with non-adapted reference SBRT plans recalculated on daily anatomy, using both constraint-level pa...
Canon Healthcare Systems USA has recently introduced a volumetric planning scan, known as the 3D Landmark, designed to support automatic exposure control (AEC), automated anatomical landmark detection for scan planning, and patie...
Volumetric-modulated arc therapy (VMAT) plan optimization remains a challenging problem due to its non-convex character and the large dimensionality of the solution space. Commonly, the problem is split in three steps: 1) ideal f...
This study quantifies how two inverse optimization-based planning parameters: dwell time deviation constraint (DTDC) and active step size (AS) affect target coverage, dose heterogeneity, and organ‑at‑risk (OAR) doses in prostate...
To quantify the accuracy of commercial dose calculation algorithms in lung SBRT planning and evaluate how lung density variations resulting from Deep Inspiration Breath Hold (DIBH) versus 4DCT motion management techniques affect...
To evaluate the impact of patient size on cone-beam CT (CBCT) image quality using iterative reconstruction approaches on the Varian Ethos HyperSight imaging system and to assess the adequacy of attenuation and scatter correction...
To investigate the difference in gamma passing rate and dose profile of measurement of patient specific quality assurance (PSQA) of SBRT plans using the SNC ArcCHECK in single measurement and high-density diode merge measurement.
Cherenkov radiation imaging has become an increasingly more common imaging modality as a real-time beam delivery visualization aid with potential for dosimetry. Dosimetric studies require a comprehensive analysis of factors which...
Multileaf collimators (MLCs) are essential in radiotherapy, and their modeling in the treatment planning system directly affects dose accuracy. This study compares the performance of the Enhanced Leaf Model (ELM) in Eclipse v18.1...
To assess the clinical implementation, contour accuracy, and workflow efficiency of a commercially available deep learning auto-contouring system for CT-based radiotherapy planning across multiple anatomical sites.
To develop an automatable standard nomenclature for field name and description to reduce field labeling errors.
Prostate stereotactic body radiation therapy (SBRT) delivered with a full bladder protocol is commonly associated with challenges in maintaining consistent bladder filling between simulation and treatment. The bladder volume achi...
This study explored the clinical feasibility of implementing simultaneous integrated boost (SIB) GRID therapy planning technique for Spatially Fractionated Radiotherapy (SFRT).
Patient-facing AI systems are increasingly used for education, yet their performance can vary widely depending on how users communicate. This study presents the development and evaluation of an AI-based chatbot designed to delive...
To assess the performance impact of transfer-learning and layer freezing training methods on a generative adversarial network (GAN)-based CT infilling technique.
Prostate High Dose-Rate (HDR) Brachytherapy with Dominant Intraprostatic Lesion (DIL) boost is well tolerated for high-risk patients. Ultrasound-guided prostate HDR is a time-sensitive procedure with treatment planning subject to...
A system matrix (SM) was designed to incorporate the distance dependent blurring in MLEM reconstruction for SPECT.
To reduce the frequency of calibration and adjustment of Elekta linear accelerator components, including MLCs, jaws, mechanical isocenter, beam spot position, symmetry, and flatness.
X-ray angiography systems are used to diagnose and treat pediatric congenital heart disease. Among the substantial variability in this patient population is that patient weight ranges from <1 kg premature infants to large adolesc...
To investigate the effect of bolus–surface air gap on surface dose calculation for a clinical 6 MV photon beam.
To assess the effect of Monte Carlo (MC) grid resolution on dose estimation in cranial radiotherapy across different tumor types.
