Free super-resolution MRI by BRICKD slices

BRICKD slices refers to shifting the field-of-view by fractional pixel increments between slices; half pixel shifts are analogous to the common brick wall layout. We demonstrate that compressed sensing reconstructions can harness the added information content of this approach and lead to improved performance over a simple stacked slices approach. The method is simple and could be easily implemented on a clinical imaging system.

BRICKD切片（BRICKD slices）指在各切片之间以分数像素增量调整视场；半像素偏移类似于常见的砖墙排布方案。本研究证实，压缩感知（compressed sensing）重建可利用该方法新增的信息内容，相较于简单堆叠切片方案，可获得更优的性能表现。该方法操作简便，可轻松在临床成像系统中实现部署。
