MRI Echo-Window Timing for Wider Reception Bands and Fewer Artifacts

The patent applies periodic action by systematically varying the acquisition window timing in a periodic manner across multiple signal collections. The acquisition window is shifted by a fixed amount (e.g., 1/N of the sampling interval) for each signal collection, creating a periodic pattern that enables the receiver to distinguish between different signal components while maintaining manageable processing complexity through the regularity of the timing variations.

The patent applies preliminary action by pre-calculating and pre-setting the acquisition window timing variations before the actual signal collection process. The timing shifts are determined in advance based on the desired reception band expansion, allowing the system to execute the sampling process with predetermined timing adjustments rather than requiring complex real-time synchronization calculations during signal acquisition.

The patent applies segmentation by dividing the signal collection process into multiple distinct phases, each with a specific acquisition window timing. By segmenting the data collection into these timed portions and using the timing variations to encode spatial information, the system can process the segmented data more efficiently through Fourier transformation, reducing overall processing time while achieving wider field of view coverage.
