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.
