We developed an efficient mathematical representation of achievable Pareto optimal OAR dose sparing objectives for lung cancer RT planning. We further incorporated these preferences in a RT planning model for individualized RT do...

To develop, compare, and validate a nomogram that uses tumor shape and size to predict seed density for Diffusing Alpha-emitters Radiation Therapy (Alpha DaRT) treatment planning with flexible and needle applicators.

In the Phase I clinical trial (NCT05831579), we already performed the palliative spatially fractionated (GRID) proton therapy by using a collimating brass aperture. However, the existence of this brass aperture limits the flexibi...

To develop an open-source application capable of retrospectively monitoring the position of radiopaque markers from bi-planar fluoroscopy images. To enable investigation of the cardiorespiratory motion of implanted cardiac leads...

Two-dimensional dosimetry for radiotherapy quality assurance commonly relies on planar detector arrays or radiochromic film. While these methods provide high spatial resolution, they are often time-consuming, single-use, and do n...

The aims of this project were to (1) develop and apply a process to optimize 3D-printing processes specifically for tissue-equivalent small-field dosimetry phantoms and, (2) design and test a 3D-printed phantom for single-isocent...

To establish, for the first time, a biomimetic nanobrachytherapy platform using radioactive gold nanoparticles coated with PANC-1 cell membrane m198AuNP. This study evaluates their physicochemical properties, nanoscale dose depos...

Current techniques for assessing setup margins in prostate and PLN radiation treatments rely on manual, time-consuming workflows. A novel automated workflow approach was developed to evaluate three clinical sites with different i...

A novel high-resolution and bias-free deuterium MRI B1+ mapping method was developed for validating the simulation accuracy of a 7T body RF coil. The extremely low SNR of X-Nuclei causes significant problems for conventional B1+...

Slow energy switching remains a limitation in proton therapy. This study aims to design and optimize an energy degrader system to accelerate layer-to-layer dose delivery in compact proton therapy systems, thereby improving treatm...

Proton arc therapy (PAT) faces two key challenges: minimizing treatment delivery time and eliminating gantry rotation velocity fluctuations. To address these, this study proposes a novel workflow that enables true dynamic arc del...

A novel, low-cost 3D surface scanning system was developed using a custom modification of the laser-profiling technique. Proof of concept was demonstrated through 3D simulation in Blender 3D software. A real-world prototype was t...

This study presents a novel non-metallic radio-opaque human photographic image printing approach developed for clinical applications in radiology and radiotherapy, with clinical implementation in patients.

The Elekta Comprehensive Motion Management (CMM) system enables real-time monitoring of tumor motion with high temporal resolution and accuracy. Using histogram analysis of tumor positional oscillations, we propose a patient-spec...

Precise proton therapy treatment planning relies on the synergy between the superior soft-tissue definition obtained from MRI and the accurate relative stopping power (RSP) maps derived from CT. However, standard workflows that u...

Unexpected toxicity during proton therapy (PT) cancer treatments may be associated with the linear energy transfer (LET) or the instantaneous dose rate. However, millisecond timescale dose rate determination becomes unfeasible in...

To evaluate the dosimetric advantages of the TaiChi radiotherapy platform—an NMPA‑ and FDA‑approved system combining LINAC and Gamma Knife technologies—for lattice radiotherapy (LRT) , comparing its dose‑escalation capability and...

A Novel system to distribute evenly and efficiently patient-specific daily, quarterly and yearly clinical workload was developed and optimized to reduce risk of burnout and create space for non-clinical activities.

To determine the appropriateness of using an anti-scatter grid in pediatric diagnostic fluoroscopy.

Fast and accurate dose calculation is a key requirement for real-time adaptive radiotherapy, particularly for emerging image-guided radiation therapy systems. Monte Carlo methods and existing treatment planning system (TPS) algor...

FLASH radiation therapy, which utilizes FLASH effect with ultra-high-dose-rate (UHDR) radiation, has shown promising performance in achieving treatment goals with decreased risks on healthy organs of patients. However, a number o...

Metal artifacts caused by implanted gold fiducial markers remain a significant challenge in cone-beam CT (CBCT) imaging for prostate radiotherapy. Their high attenuation generates severe streaks and image distortions that decreas...

To develop and validate a log file-based patient quality assurance (LFQA) system for intensity modulated proton therapy (IMPT) using a GPU-accelerated pencil beam algorithm for dose reconstruction, permitting rapid log file uploa...

Y90 radioembolization often requires both fluoroscopy and CBCT to guide the complex treatment procedure. However, radiation data in the form of RDSRs and Dose Sheets are usually combined across these imaging modalities, making it...
