Primary Magnet Actuation for Precise MRI Field Alignment

The patent applies the dynamics principle by implementing adjustable and reconfigurable magnetic field components that can dynamically change their spatial configuration. The primary magnetic field system includes actuators that enable movement along multiple spatial degrees of freedom, allowing the homogenous region to be dynamically repositioned and reoriented to achieve precise alignment with the drive magnetic field for different sample geometries and experimental conditions.

The patent applies segmentation by dividing the magnetic field system into independent, modular components. The primary magnetic field is generated by separate magnet assemblies (e.g., Halbach arrays) that can be independently positioned and oriented. This modular approach allows each component to be adjusted separately, achieving precise alignment while maintaining manageable system complexity through functional decomposition.

The patent implements dynamics by incorporating motorized actuators and adjustment mechanisms that enable precise control of the primary magnetic field position and orientation even in a compact configuration. The system can dynamically adjust field parameters through controlled movement, ensuring high alignment precision is maintained despite the mobile and space-constrained design.

The patent applies mechanics substitution by replacing manual mechanical adjustment systems with electronically controlled actuators and positioning systems. This allows for precise, repeatable adjustments to be made programmatically, maintaining high adjustment precision while reducing the physical space required for manual operation and improving ease of use through automated control.
