Qihui Lyu

Qihui Lyu is an Assistant Professor in Residence at the University of California San Francisco (UCSF) Department of Radiation Oncology. She holds a PhD in Medical Physics from UCLA (2021) and completed clinical training at the UCLA Medical Physics Residency Program (2023). Her research focuses on image reconstruction, dual-energy CT, treatment plan optimization, and machine learning applications in radiotherapy.

• Education: B.S. in Physics (Nanjing University, 2016), Ph.D. in Medical Physics (UCLA, 2021)
• Research: Optimization algorithms for image-guided radiotherapy, machine learning in radiation oncology, and dual-energy CT applications
• Awards: AAPM BEST award (2022), Early-Career Investigator Symposium First Place (2022), Norm Baily Awards First Place (2022)

Her publications emphasize advanced optimization techniques for volumetric modulated arc therapy (VMAT), proton therapy, and FLASH radiotherapy systems, with recent work on deep learning denoising and dual-layer multi-leaf collimator (MLC) integration. Collaborative projects include HDR prostate brachytherapy planning and high-energy X-ray dosing monitoring via tomographic photon detection.
