在小口径2.0T磁共振显微镜上，用自聚焦选择脉冲进行投影重建，使肺实质成像。扫描同步通气和心脏门控已与序列集成，以最大限度地减少运动伪影。结合生物门控参数对脉冲序列参数进行了系统的调查，以优化分辨率和信噪比（SNR）。所得到的投影图像的有效回波时间为
Projection reconstruction has been implemented with self refocused selection pulses on a small bore, 2.0 T MR microscope, to allow imaging of lung parenchyma. Scan synchronous ventilation and cardiac gating have been integrated with the sequence to minimize motion artifacts. A systematic survey of the pulse sequence parameters has been undertaken in conjunction with the biological gating parameters to optimize resolution and signal-to-noise (SNR). The resulting projection images with effective echo time of
