The second conversation

Targeting tumors in the blink of an eye:
Freezing motion and sparing healthy tissue.

In this episode of The FLASH Effect, host Justin Starbird sits down with Dr. Bill Loo, Co-Founder, Chief Medical Advisor, and Board Member at TibaRay, and Professor of Radiation Oncology at Stanford Medicine. Dr. Loo shares how his background in bioengineering led him to radiation oncology and explains the persistent challenge clinicians face: treating tumors that move continuously as a patient breathes. He reveals how TibaRay is flipping that equation with ultra-fast FLASH radiotherapy and the proprietary Galactica™ linear accelerator platform—delivering curative radiation doses in a fraction of a second to freeze motion in place and protect healthy organs.

The physics.
The biology.
The patient impact.

  • How an accidental course flyer at UC Davis sparked Dr. Loo's career in bioengineering and oncology
  • The moving target dilemma: sharpshooting tumors while patients breathe
  • Flipping the paradigm: freezing tumor motion with sub-second radiation bursts
  • The Curie Institute discovery: why FLASH radiotherapy drastically spares healthy normal tissue
  • Why existing electron and proton approaches fall short of delivering deep 3D conformal FLASH
  • The Galactica™ linear accelerator: next-generation particle accelerator physics from SLAC
  • Upright radiotherapy with Leo Cancer Care: enhancing patient comfort, clinic throughput, and global access
  • Community-backed innovation: why Reg CF on Wefunder empowers everyone to participate in curing cancer

The conversation explores technology under development and its potential. Clinical validation remains part of the road ahead.
