FLASH Radiotherapy can destroy tumors in under a second — if the beam is measured precisely enough.
We build the fast, reliable beam-monitoring technologies that make ultra-high-dose-rate radiotherapy clinically viable. A scientific spin-off from LIP and Instituto Superior Técnico.
Particle physics expertise, engineered for the clinic
RTBeamTech translates decades of high-energy physics instrumentation experience from LIP and IST into robust, scalable beam-monitoring systems for the next generation of radiotherapy.
Built on instrumentation experience from LIP researchers.
Physicists, engineers and clinical specialists working side by side.
Active collaborations across leading European FLASH-RT programs.
Guided by international leaders in accelerator and medical physics.
Beam monitoring for ultra-high dose rates
Real-time beam monitor
Sub-microsecond dose readout engineered for FLASH-RT delivery rates.
