A new optimizer is planned for the ZAP-X stereotactic radiosurgery (SRS) treatment planning system (TPS) upgrade version 1012, utilizing a Krylov algorithm. In this study, ZAP-X TPS 1012 beta version is evaluated against the curr...
Show the Gamma Index passing rates (GPR) for selected groups of patients treated with Lattice Radiotherapy using a high resolution solid-state detector. This study evaluates the accuracy of dose distribution for high gradient dos...
Cherenkov imaging (CI) provides direct, real-time visualization of dose on a patient's surface and has been used for treatment verification and error detection in radiation therapy. However, clinical adoption of CI remains in its...
We share our institutional experience upgrading Varian ARIA to v18.1/18. 2 in a multi-vendor radiation therapy environment, highlighting practical challenges, mitigations, and actionable lessons for centers planning similar upgra...
Accurate radiotherapy for brain tumors requires highly conformal dose delivery to maximize tumor control while limiting damage to adjacent critical neural structures. Although intensity-modulated radiotherapy (IMRT) is routinely...
This study evaluated the impact of interfractional rectal state changes on plan robustness in cervical cancer intensity-modulated proton therapy (IMPT) and established a robust optimization strategy incorporating multiple rectal...
Inter-fraction variations in bowel and bladder filling during rectal cancer radiotherapy can cause positional and dosimetric deviations, potentially compromising treatment accuracy. This study aimed to evaluate the morphological...
To evaluate inter-institutional variability in the computed tomography dose index (CTDI) and aluminum half-value layer (HVL) for ClearRT (Accuray, Inc., Sunnyvale, CA), and to assess the consistency of imaging dose and beam quali...
Accelerated partial breast irradiation (APBI) combined with online adaptive radiotherapy (OART) offers precise treatment of early-stage breast cancer, but inter-observer variability (IOV) in target delineation must be accounted f...
To establish the feasibility and a development pathway for a fully mobile radiotherapy facility to improve treatment access for rural and remote Western Australians.
To understand underlying differences in beam modeling leading to occasionally falling gamma analysis criteria
The Varian Ethos intelligent optimization engine (IOE) automates the generation of non-overlapping optimization structures and resolves planning conflicts via a prioritized goal hierarchy. While designed to minimize manual interv...
To investigate treatment plan quality of head and neck cancers via tumor control and normal tissue complications probability (TCP and NTCP) objectives in the plan optimization process.
To demonstrate a novel method of quantifying respiratory gating beam-on and beam-off latency for Varian TrueBeam linear accelerators and assess the impact of dose rate and machine-specific factors on overall timing performance.
The dielectric wall accelerator (DWA) offers a low-cost solution for proton therapy with non-resonant waveguides. Radial waveguides (RWGs) transport electronically-switched nanosecond pulses and produce an accelerating electric f...
Metals in computed tomography (CT) scans often saturate image pixel values, making low- and high-density metals indistinguishable. The purpose of this work was to test the effectiveness of the extended HU mode on a GE Discovery R...
To quantify the usage of different electron beam treatments and use that data to develop recommendations for maximizing efficiency in electron output factor measurements.
Diffuse midline glioma (DMG) is an aggressive central nervous system malignancy typically affecting children and requiring urgent radiotherapy treatment. This study evaluates the application of knowledge-based planning to expedit...
To evaluate agreement between LLMs and expert reviewers in triaging radiation oncology incident learning system (ILS) forms with regard to three clinically relevant dimensions (workflow process step, severity, and dosimetric impa...
The radius and spacing of high-dose spheres (HDS) in Lattice Radiotherapy (LRT) used by clinicians varies considerably This study quantifies how changing these parameters impacts dosimetric characteristics (such as peak-to-valley...
Commissioning of horizontal Leipzig applicators in HDR typically includes determination of the effective distal source position and output verification using a suitable chamber. In addition to those methods, we previously describ...
Despite the global transition toward more precise and conformal radiotherapy, many countries currently treat with Co-60 units. This paper describes key steps, challenges and lessons learned from a successful transition from Co-60...
