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.
