论文摘要
对于漂移校正和实时可视化，需要进行缓慢扫描的图像的逐步获取。交织方法是直线网格上存储和传输数据的常见方法，在这里我们建议在扫描模式图像模态中使用它们来获取。特别是在这些情况下，必须最佳地使用样品点以加快扫描并减少对受试者的损害。早就知道，使用六角扫描网格可以实现带限制信号的最佳采样。在本说明中，我们演示了两种交织六角形网格的新方法，它们可以通过最佳采样和分辨率加倍的早期全景成像。
Progressive acquisition of slowly-scanned images is desirable for drift correction and real-time visualization. Interlacing methods are common approaches to storing and transmitting data on rectilinear grids, and here we propose using them for acquisition in scanning-mode image modalities. Especially in these cases, it is essential to make optimal use of sample points to speed up the scan and reduce damage to the subject. It has long been known that optimal sampling of band-limited signals is achieved using hexagonal scanning grids. In this note, we demonstrate two new methods for interlacing hexagonal grids, which enable early full field-of-view imaging with optimal sampling and resolution doubling.
