High Resolution Linac MLC for Modern Radiotherapy Platforms
Modern oncology depends on high resolution beam modulation to target malignancies while protecting healthy tissue. We provide the Linac MLC hardware necessary to execute complex radiation protocols with exact dose conformity. Our unified engineering workflow ensures that your radiotherapy platform moves from initial concept to certified series production without friction.
Modern Oncology Treatment Methods
Clinicians utilize advanced fractionated protocols to target tumors with submillimeter accuracy. These methods require real time adaptation of the radiation aperture to match the moving or static geometry of the target.
Intensity Modulation
IMRT modulates beam intensity across several fields to conform to complex tumor shapes.
Arc Delivery
VMAT rotates the gantry while the Linac MLC leaves move to optimize dose distribution.
Stereotactic Targeting
SBRT delivers high doses to small targets using steep dose gradients and submillimeter leaf resolution.
Adaptive Adjustment
Clinicians adjust the treatment plan based on daily changes in patient anatomy or tumor position.
Our Linac MLC Solutions
We offer two distinct paths for integrating multileaf collimation into your linear accelerator architecture.
Standard Linac MLC
The EMM120 serves as a ready to integrate Linac MLC utilizing 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 40 kHz double loop PID control. A shuttle system enables 101 percent overtravel to manage the intricate field geometries required for VMAT protocols.
Customized Linac MLC
We develop bespoke Linac MLC designs to meet the technical needs of FLASH, proton, and MRI guided therapy. These specialized units incorporate piezo actuators or amagnetic materials to eliminate interference in high field magnetic environments. Our team adjusts leaf thickness and micro geometry to provide high resolution modulation for stereotactic radiosurgery and small animal research.
