Dynamic Beam Shaping: Submillimeter Leaf Control for Radiotherapy Platforms
High resolution radiotherapy depends on dynamic beam shaping to shield critical organs during complex oncology treatments. We merge mechatronic engineering with medical certification to turn your clinical vision into a validated hardware system. This unified development process bridges the gap between an early sketch and full series production for OEM partners.
Challenges in Modern Radiation Therapy
Modern radiotherapy demands fast leaf motion and repeatable dose conformity to target moving tumors. Siloed engineering stages often create integration complexity that slows the development of next generation linear accelerators.
Integration Obstacles
Closed or proprietary interfaces slow down OEM development and linear accelerator integration.
Field Limitations
Collimators often only work for a specific device which forces OEMs to accept compromises during cross platform integration.
Maintenance Downtime
Non modular designs require full system disassembly during service and increase operational costs in clinical environments.
Incompatibility Risks
Standard systems often contain ferromagnetic materials that interfere with MRI based guidance or hybrid imaging.
Our Dynamic Beam Shaping Devices
Standard MLC Systems
The EMM120 platform enables dynamic beam shaping through 120 tungsten leaves to cover a 40 x 40 cm field. This hardware reaches leaf speeds above 50 mm/s while maintaining a positioning resolution below 0.2 mm through high resolution PID control. Industry gold standard DC motors and integrated encoders provide immediate feedback for real time verification of the beam aperture.
Customized Collimator Solutions
We design bespoke dynamic beam shaping architectures using piezo actuators or amagnetic materials for FLASH, proton, and MRI guided therapy. Our engineering team adjusts leaf thickness and micro geometry to provide high resolution modulation for stereotactic radiosurgery and small animal research. Cooperation with OEM development teams through CAD exchange and rapid prototyping fast tracks the launch of specialized treatment platforms.
Applications of Dynamic Beam Shaping
- Adaptive Radiotherapy: Real-time field adaptation for anatomical motion compensation.
- FLASH Radiotherapy: Ultra-fast beam modulation for next-generation high dose rate therapy.
- MRI-Guided Radiotherapy: Amagnetic collimator systems for hybrid imaging environments.
- Stereotactic Radiosurgery: Submillimeter beam shaping for high-dose precision treatments.
- Proton Therapy Research: Custom beam modulation architectures for particle therapy platforms.
Technical Advantages
Repeatable Field Resolution
High resolution PID logic ensures exact leaf positioning for every fractionated treatment. The drive system achieves a resolution below 0.2 mm to support the tight tolerances of stereotactic protocols.
Dose Shielding Accuracy
Tongue and groove leaf designs minimize interleaf leakage to below 1% to protect healthy tissue. The 80 mm height tungsten leaves provide the necessary density for high energy photon and electron beams.
Unified Control Logic
Open UDP and TCP/IP protocols facilitate a direct connection to your existing linear accelerator software. This modular interface supports real time synchronization of leaf movement with the radiation source.
Audit Ready Compliance
We align every development step with ISO 13485 and ISO 14971 standards to simplify your certification process. This integrated risk management ensures that the hardware remains compliant with CE marking and FDA safety requirements.

FAQ: Frequently Asked Questions for Dynamic Beam Shaping
What is Dynamic Beam Shaping?
Dynamic beam shaping refers to the real time adaptation of a radiation beam to match the moving or static geometry of a tumor. It utilizes multileaf collimators to modulate the aperture during treatment and ensure high resolution dose delivery.
How do your systems integrate with OEM LINAC architectures?
Our systems connect directly to OEM architectures via Ethernet using open TCP/IP or UDP control protocols. This setup allows for real time synchronized beam logic and position verification without proprietary barriers.
Which standards apply to the design of dynamic beam shaping hardware?
Development follows ISO 13485 for quality management and ISO 14971 for risk management. Additionally, the hardware meets IEC 60601-1 and IEC 60601-2-1 standards for safety in radiotherapy environments.
Can you customize dynamic beam shaping solutions for MRI guided therapy?
Yes, we offer customized MLC systems using non magnetic materials for hybrid imaging environments. These designs eliminate interference with MRI based guidance while maintaining high resolution beam control.
