Simplify's Take

What believers are saying

  • ARPA-H awarded Varian up to $60 million in April 2026 for FLASH-RT.
  • FDA cleared TrueBeam for osteoarthritis in March 2026, opening a non-cancer market.
  • Telix collaboration and 2026 AI approvals expand Varian's clinical and software pipeline.

What critics are saying

  • RaySearch enabled online adaptive TrueBeam workflows in Belgium in May 2026, eroding software differentiation.
  • Elekta still attacks Varian's lead in adaptive radiotherapy and premium MR-guided care.
  • If FLASH and non-oncology bets fail by 2028, Varian becomes a commoditized linear-accelerator vendor.

What makes Varian unique

  • Siemens Healthineers gives Varian imaging, radiotherapy, and capital-sales integration globally.
  • Varian's 2026 CE-marked Eclipse AI contouring deepens workflow lock-in across planning.
  • TrueBeam, Halcyon, and Ethos create an installed-base moat hospitals rarely replace.

Siemens Healthineers secures $83M to develop photon Flash radiotherapy for cancer treatment

Siemens Healthineers has received up to $60 million from the US Advanced Research Projects Agency for Health to develop photon Flash radiotherapy, with the company contributing an additional $23 million, totalling $83 million over five years. Flash photon therapy delivers radiotherapy more than 100 times faster than current technologies, aiming to reduce side effects and improve healthy tissue sparing. Unlike proton and electron beam platforms, which face scalability challenges, photon beams are the standard of care for over 50% of cancer patients. The project will build on existing C-arm linear accelerators to enable broader clinical access. Siemens Healthineers aims to transition ultra-high dose rate radiotherapy from experimental treatment into global standard of care within the five-year timeframe.

Varian TrueBeam gets FDA clearance for low-dose radiotherapy to treat osteoarthritis

Siemens Healthineers has received FDA 510(k) clearance for its Varian TrueBeam radiotherapy systems to treat medically refractory osteoarthritis in adults using low-dose radiation therapy. This marks the first expansion of Varian's radiotherapy platform beyond cancer care into chronic musculoskeletal conditions. Osteoarthritis affects over 33 million adults in the US and approximately 600 million globally. The clearance covers TrueBeam, TrueBeam STx, VitalBeam and Edge systems, offering patients with persistent pain a non-invasive outpatient treatment option that targets inflammation, reduces pain and improves joint function. The approval builds on Varian's previous regulatory clearances for non-oncological indications, including radiosurgery treatment for medically refractory essential tremor. The TrueBeam platform combines high-resolution imaging with precise dose control whilst maintaining streamlined clinical workflows.

Telix and Varian enter research collaboration

Telix and Varian enter research collaboration. Telix Pharmaceuticals and Siemens Healthineers' company Varian have agreed to develop novel clinical applications that combine Telix's theranostics products and Varian's external beam radiation therapy (EBRT) technology. The first area of focus will be in identifying opportunities to use Telix's prostate cancer PET imaging agents in selecting patients for EBRT, developing personalized treatment plans (particularly in the context of Varian's Ethos adaptive radiotherapy system), and monitoring responses to treatment, Telix said. The agreement supports both company-sponsored and investigator-led clinical studies. Varian is a key player in EBRT and working with the company will allow Telix to explore how theranostics can be used more effectively by radiation oncologists to enhance patient selection and deliver targeted treatment, Telix noted.
