我们提出了一种与相位对比MR血管造影兼容的相控阵多线圈数据重建方法。所提出的算法可以产生复数差或相位差血管造影。相位差重建保留了方向流和定量信息。该方法计算效率高，避免了速度混叠边界附近的线圈间抵消误差。该方法的可行性证明了人体扫描。
We present a reconstruction method for phased array multicoil data that is compatible with phase contrast MR angiography. The proposed algorithm can produce either complex difference or phase difference angiograms. Directional flow and quantitative information are preserved with the phase difference reconstruction. The proposed method is computationally efficient and avoids intercoil cancellation errors near the velocity aliasing boundary. Feasibility of the method is demonstrated on human scans.
