MRI‑guided linear accelerators (MR‑Linacs) enable real‑time adaptive radiation therapy by allowing daily plan adaptation based on anatomical changes. In pancreatic cancer, substantial interfraction motion and proximity to gastroi...
To determine image quality performance of Accuray ClearRT as a substitute for Philips Big Bore CT Simulator.
The purpose of this study is to evaluate allowed treatment dose for a palliative treatment of spinal lesion. NCRP report 174 recommends the limit of a total dose to embryo of 0.1Gy during a course of radiation treatment. We perfo...
Due to the dose engine algorithm, there is a gap between Independent secondary dose calculation (ISDC) and the treatment planning system algorithm for small fields, inhomogeneity environment correction, and online adaptive plan Q...
MRI guided Adaptive Radiation Therapy (MRgART) allows for daily plan adaptation to the patient’s anatomy. This is achieved by imaging the patient before each fraction, editing the contours to the new anatomy, and adapting the pla...
To evaluate beamlet sequence delivery patterns in biology-guided radiotherapy (BgRT) on a linac machine with an integrated PET scanner and a binary multileaf collimator (MLC) using beamlet sequence log data from daily treatments.
To compare the traditional Computed Tomography Dose Index (CTDI) and the Cone-Beam-Dose-Index (CBDI), an alternative metric that quantifies the average dose in the central region of a cone-beam CT (CBCT) scan, for imaging dose me...
We compared denoising methods for Diffusion-Weighted Imaging (DWI) of phantoms acquired on a low-field MR-Linac to determine which method best preserves Apparent Diffusion Coefficient (ADC) accuracy and image feature detection. O...
This study evaluates the dosimetric impact and treatment delivery parameter differences between HyperArc (HA) volumetric modulated arc therapy (VMAT) and non-coplanar VMAT treatment planning for intracranial fractionated stereota...
To assess the dosimetric impact of systematic source position uncertainty along the source path during MRI-guided gynecological high-dose-rate (HDR) interstitial brachytherapy (ISBT) treatment planning.
Spine SBRT involves steep dose gradients near critical organs at risk, making treatments highly sensitive to intrafraction motion. This study evaluated the performance of immobilization devices used for LINAC-based upper spine (T...
RapidPlan (RP) was utilized to potentially reduce variability of plan quality and decrease optimization times. When implementing a new treatment delivery system such as the Halcyon, planners may require time to establish a datase...
Lattice radiotherapy (LRT) is a spatially fractionated radiation therapy technique in which high‑dose vertices are delivered within a gross tumor volume while maintaining lower‑dose valley regions. The technique requires reliable...
To identify a preferred institutional strategy for planning LUNG SBRT cases on version 18 of ECLIPSE using the photon optimizer (PO), four planning strategies were compared. The first strategy involved limiting the number of moni...
4D motion management in particle therapy requires accurate and reproducible respiratory surrogate signals. The Anzai pressure belt and optical tracking systems are used for respiratory motion monitoring; however, temporal synchro...
For BgRT treatment on the RefleXion X1 linac, patients must meet stringent criteria regarding the proximity and 18F-FDG activity of OARs near the target. The next-generation X2 platform has an increased PET field of view, and new...
VMAT post-mastectomy and regional lymph node irradiation is a highly complex technique that requires multiple planning iterations to achieve adequate coverage while minimizing OAR doses. RapidPlan, a Varian knowledge-based modeli...
This study evaluates the effect of virtual bolus (VB) thickness on skin dose in TomoHelical total body irradiation (TBI) using two treatment planning systems (TPSs): Accuray Precision and RaySearch Laboratories RayStation (RS).
Spine stereotactic body radiotherapy (SBRT) requires high precision due to the anatomical proximity of target to the spinal cord and steep dose gradients. Rotational setup errors (SE) can affect the dose delivery to targets and o...
Ultra-high dose rate (UHDR) beams (40Gy/s) compromise the accuracy of conventional reference ion chambers (ICs) due to saturation effects. The Exradin A30 is an ultra-thin parallel-plate IC featuring a 0.3 mm nominal electrode sp...
To evaluate the suitability of the RTI Dose Probe for monitoring daily output constancy of SXRT machines.
Aim of study is to compare MPC output measurements with daily output measured by PTW Quick-Check and Ion chamber Based measurements for Varian Ture-Beam linear accelerator (LINAC).
RayStation’s Fallback Planning (FBP) uses dose mimicking to automatically generate a new radiotherapy plan from an existing plan using a different treatment modality, technique, or unit. This facilitates contingency planning in t...
To reflect on a meaningful early experience of research, learning, and professional growth within a radiation oncology department under the mentorship of a medical physicist
