To validate the treatment planning system (TPS), RayStation 11B, for IMRT treatment deliveries on the 0.5 T Biplanar Linac-MR (Aurora-RT)

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) algorithms do not achieve the compu...

To evaluate the generalizability of a deep learning (DL)-model, trained exclusively with external beam radiotherapy (EBRT) organs‑at‑risk (OARs) contours, for autocontouring in cervical cancer brachytherapy (CC-BT).

To investigate internal treatment margins for targets undergoing cardiorespiratory motion with the use of dynamic tracking technology.

To exploit differences in J-coupling evolution of the ≈2 ppm fat allylic protons (neighbor the two ends of the double bond chain) to estimate relative linolenic acid content at 3 T. Oleic (mono-unsaturated), linoleic (di-unsaturated) and linolenic acid (tri-u...

This work investigates use of the IMR algorithm in 4DCT for potential dose reduction in patients.

To simulate prostate treatment plans with Monte Carlo (MC) and compare with dose calculations from RayStation 11B (RS-11B) treatment planning system (TPS) for a 0.5 T bi-planar inline Linac-MR (LMR).

To report on a GUI-driven program “IGOR” (Interplay & Gradient Outcomes in Radiotherapy) which simulates MLC interplay and gradient effects accounting for the tumor’s phase of motion at the start of treatment, and the different tumor start-phases of motion be...

To resolve the glycerol-CH2 resonance (≈4–4.4ppm) from that of water (≈4.7ppm) in 1H magnetic resonance spectroscopy (MRS) at 9.4T.

Magnetic resonance (MR) imaging is routinely used to contour targets for stereotactic radiotherapy planning. However, MR images can suffer from susceptibility-induced geometric distortions, especially near air-tissue interfaces. The objective of this work is...

To develop and validate a Monte Carlo model of a dual-layer flat-panel detector for image-guided radiotherapy applications; to optimize the design and material composition to improve spectral separation while maintaining clinically acceptable image quality.

To develop the first quadrature RF volume coil for 10.5T MRI, using metasurface technology to overcome limitations of traditional volume coil designs.

To automate the cervical cancer brachytherapy (CC-BT) planning process using two

Over the past two decades Radiation Therapy has become increasingly reliant on complex software systems, locally developed scripts and spreadsheets. Recent advances in AI technology suggest that this reliance will only increase in the future. While software e...

MRI-radiotherapy hybrid systems enable real-time guidance of the therapeutic beam by dynamically adapting to tumor motion. However, inherent delays in imaging and beam control demand prediction of the tumor’s future position and shape for accurate targeting....
