Figure 6

A sequence of MART reconstructions of Figure 5 Middle, with increasing numbers of views: 5, 6, 9, 18, 36, and 72, equally spaced in angle. These were generated by using the CT Brush code, looping the central-point of the CT brush through all of the pixels (each initially set to 1), and refining until convergence. Such “traditional” CT images provide a visual comparison with the player driven, object dependent CT Brush reconstructions in Figure 3. Of course they have more uniform spatial resolution, as the point spread function is approximately spatially homogeneous [63,65,67].
