MRI Acoustic Warning via Command Segmentation

The patent segments preparatory scan commands into two distinct categories: fixed duration commands and indeterminate duration commands. This segmentation allows the system to accurately predict when loud noises will occur by calculating the sum of fixed duration commands and adding a predetermined offset, while indeterminate duration commands are executed first without affecting the warning signal timing. The segmentation resolves the contradiction by enabling reliable warning signal provision without introducing unnecessary delays.

The patent executes indeterminate duration preparatory scan commands before fixed duration commands. This preliminary action ensures that all unpredictable preparatory operations are completed before the timing-critical phase, allowing the warning signal to be provided at a predictable time based solely on the fixed duration commands. This resolves the contradiction by eliminating uncertainty from the warning signal timing calculation.

The patent segments preparatory scan commands into fixed duration and indeterminate duration categories. Fixed duration commands contribute to both system configuration and predictable noise timing, while indeterminate duration commands handle unpredictable configuration tasks first. This segmentation resolves the contradiction by separating the unpredictable configuration tasks from the timing-critical path, enabling accurate noise timing prediction.

The patent executes indeterminate duration preparatory scan commands as preliminary actions before fixed duration commands. This ensures that all unpredictable system configuration tasks are completed beforehand, allowing the subsequent fixed duration commands to provide a reliable basis for noise timing prediction. The preliminary execution of indeterminate commands resolves the contradiction between configuration reliability and timing predictability.
