- **Caution**: 
- **Caution**: 

### Q: What materials are used in the LINAC gantry construction for durability and precision?
**A**: Our LINAC gantry utilizes high-strength steel alloy for structural integrity, precision cast components for accurate alignment, and reinforced composites to reduce weight while maintaining stability during rotation.

### Q: How does the isocenter verification system ensure treatment accuracy?
**A**: The integrated isocenter verification system continuously monitors and calibrates the radiation beam's focal point, ensuring consistent targeting accuracy within sub-millimeter tolerances throughout gantry rotation.

### Q: What maintenance is required for the gantry's rotational bearing assembly?
**A**: The rotational bearing assembly is designed for minimal maintenance with sealed lubrication and wear sensors. Recommended periodic inspections include checking torque specifications, lubrication levels, and monitoring system feedback for smooth operation.
