In this paper, we report on the development of a novel multiple thin-slab projection-reconstruction acquisition technique. To eliminate the slab boundary artifact, the slabs are highly overlapped and only a small fraction of the projection view angles are sampled at each slab position. After Fourier transformation in the slice direction, there are sufficient numbers of projection measurements at each slice position to obtain very high resolution MR angiograms. The technique presented has all of the advantages of multiple overlapping thin slab acquisition (MOTSA) with no evidence of slab boundary artifact. J. Magn. Reson. Imaging 1999;10:569-575.
在本文中，我们报告了一种新型多薄板投影重建采集技术的发展情况。为消除薄板边界伪影，各薄板高度重叠，且在每个薄板位置仅对一小部分投影视角进行采样。在切片方向进行傅里叶变换后，每个切片位置有足够数量的投影测量值，以获得高分辨率的磁共振血管造影图像。所提出的技术具备多重叠薄板采集（MOTSA）的所有优点，且无薄板边界伪影迹象。《磁共振成像杂志》1999年；10：569 - 575。
