Standard MLC - Model Standard MLC -EMM 120 -Multileaf Collimator for Precise Field Shaping

SHARE

Our EMM120 Standard MLCs are compact, robust and cost-effective solutions for clinical and OEM beam-shaping applications. With a 40×40 cm field shaped by 120 leaves and a highly dynamic speed control, they cover a wide range of use cases – offering precise field shaping, optimized leaf geometry and compatibility with conventional radiotherapy system architecture.

Why Conventional Collimators Fall Short in Radiotherapy

Modern radiotherapy demands fast, accurate beam shaping and reliable dose conformity. Conventional collimators often lack the control precision, integration flexibility, and durability required for OEM and clinical use.

The EMM120 Standard MLC eliminates these limitations through gold standard specs, precise motor control, and open integration protocols. Built in Germany under ISO 13485, it provides stable beam shaping, long-term reliability, and OEM-ready interfacing for global radiotherapy systems.
