Figure 3
Schematic of the Tomosaic data collection approach, providing detail beyond Fig. 1[link]. The rotation stage is first moved to projection position P1, and the specimen is then rotated through [N_{\theta}] angular positions over a 180° range. This yields a mosaic ring projection dataset M1. This is continued for all of the Nmosaic fields of view. In order to obtain a complete projection image at one rotation angle indexed by [i_{\theta}], one must extract the corresponding projections from all of the mosaic ring datasets Mimosaic as shown on the right. In this example, the number of mosaic fields of view is Sx = 6 and Sz = 4, yielding Nmosaic = 24.
