Why Conventional Collimators Fall Short in Next-Gen Radiotherapy
Emerging treatment technologies like adaptive, MRI-guided, and proton radiotherapy demand performance beyond standard MLC systems. Conventional collimators often lack the speed, customization, and electromagnetic compatibility required for these workflows.
Limited Customization
Fixed geometries and mechanical constraints restrict OEM design flexibility for new beamline concepts.
Incompatibility with MR Systems
Standard MLCs contain ferromagnetic materials both in the tungsten alloy and in the frame that interfere with MRI-based guidance and hybrid imaging systems.
Slow or Inflexible Motion
Traditional motor drives cannot deliver the submillisecond response or motion profiles required for gated or 4D treatments.
Integration Barriers
Closed interfaces complicate system development, limiting synchronization with robotic arms or adaptive planning software.

Frequently Asked Questions
What customization options does gKteso offer for multileaf collimators?
We offer fully tailored MLCs for adaptive radiotherapy, proton therapy, and compact or MRI-guided LINAC systems. Options include variable leaf thicknesses, robotic integration, dual-layer configurations, and narrow-leaf designs for stereotactic applications. Our portfolio spans from 80 up to more than 160 leaves.
Can your custom MLCs be integrated into MRI-compatible systems?
Yes. We developed and built several designs of MR-compatible multileaf collimators with low-EM designs, non-magnetic components, and radiation-shielded cabling – ideal for MRI-Linac and hybrid imaging-guided systems.
How fast can the leaves move in your robotic or micro-MLCs?
Depending on configuration, our leaf motion systems enable speeds up to 10 cm/s with <0.1 mm micropositioning – supporting 4D, gated, or motion-managed radiotherapy protocols.
What services do you provide to OEMs developing new radiotherapy platforms?
We support full co-development workflows, including CAD file exchange, on-site testing, firmware customization, and CE/FDA documentation. Our engineering team collaborates closely with OEMs throughout the design and integration lifecycle.
Can your MLC technology be adapted for emerging radiotherapy modalities?
Yes. Our modular architecture allows adaptation for FLASH, electrons, protons, and other novel modalities. By combining piezo-driven precision, touchless sensing, and scalable leaf configurations, we can tailor the system’s footprint, speed, and beam-shaping performance to match unique research or clinical requirements – whether ultra-compact for robotic systems or high-power for large-field treatments.
