Keywords: Low-Field MRI, Low-Field MRI
Motivation: The prolonged scanning time of very-low field (VLF) magnetic resonance imaging (MRI) scanners diminishes both patient comfort and operational efficiency.
Goal(s): Our objective was to cut scanning time by half.
Approach: We developed a parallel imaging (PI) technique containing an eight-channel phased-array coil and parallel imaging (PI) method tailored for VLF MRI scanners.
Results: Head imaging experiments on healthy volunteers demonstrated that the proposed PI technique outperformed two commonly used PI methods, enabling the VLF MRI scanner to achieve comparable image quality with a 72.5% increase in signal-to-noise ratio (SNR) relative to fully sampled images, while reducing the scanning time by over 50%.
Impact: We introduce, for the first time, a PI technique specifically tailored for VLF MRI scanners. This technique halves the scanning time, which could be especially beneficial for stroke patients requiring VLF MRI assessments.
