FLASH radiotherapy (>40 Gy/s) demonstrates normal tissue sparing while maintaining tumor control, but pulse width variations systematically alter electron beam energy through waveguide loading effects, creating treatment planning system (TPS) challenges. This...

Neck CT protocols often present challenges for objective lesion detectability tasks. We systematically assessed lesion detectability in clinical scans to identify quality gaps and dose utilization inefficiencies.

To evaluate neck CT image quality (IQ) and dose efficiency for lesion assessment across multiple scanners, identifying scanner-level differences and protocol optimization opportunities.

The goal of this project was to investigate whether the FLASH effect can be preserved when an ultra-high-dose-rate (UHDR) delivery is split into multiple beams (2, 4 or 6), all delivered within a time window (5 sec) that was previously shown to preserve the s...

Manual background selection for contrast-to-noise ratio (CNR) calculations in CT image quality assessment is time-consuming, operator-dependent, and introduces >15% measurement variability that compromises reproducibility. Advanced metrics such as Noise Power...

To validate and deploy a complete applicator-specific phase space file library for the GMV Radiance treatment planning system, establishing the first clinically ready Monte Carlo-based treatment planning system (TPS) for electron FLASH radiotherapy.
