Product Specifications

Technical details and manufacturing context for Collimator System

Definition
A critical component of a Radiation Therapy Simulator that precisely collimates and shapes X-ray or radiation beams to match the treatment area, ensuring accurate targeting while minimizing exposure to surrounding healthy tissues. It consists of adjustable lead or tungsten shutters that define the beam's size and shape.
Working Principle
The system uses movable high-density metal leaves or jaws (typically made of lead or tungsten) that are mechanically or digitally adjusted to create an aperture. This aperture blocks unwanted radiation, allowing only a beam of specific dimensions and shape to pass through, which corresponds precisely to the tumor or treatment area being simulated.

Engineering Reasoning
0.1-2.0 mm focal spot diameter at 1.5 m distance
>5 μm cumulative mechanical misalignment or >0.5° angular deviation from optical axis
Design Rationale: Thermal expansion mismatch between tungsten collimator blades (α=4.5×10⁻⁶/K) and aluminum housing (α=23.1×10⁻⁶/K) causing mechanical binding at ΔT>40°C
Risk Mitigation (FMEA)
Trigger Lead screw backlash exceeding 10 μm due to wear
Mode: Collimator blade positioning error >200 μm
Strategy: Dual-encoder feedback system with 1 μm resolution and automatic backlash compensation algorithm
Trigger Coolant flow reduction below 0.5 L/min causing localized heating
Mode: Thermal lensing effect with >λ/4 wavefront distortion at 632.8 nm
Strategy: Redundant cooling loops with flow sensors and Peltier-based temperature stabilization to ±0.1°C
