Results for the simulation study. a Coronal views of the uncorrected, xMLAA-based, and ground truth (GT) attenuation maps and corresponding activity distributions. The red box indicates the 3D region used during evaluation. b Transversal views of the xMLAA-based and ground truth (GT) attenuation maps and corresponding activity distributions. The yellow circle illustrates the outer boundary of the hardware mask. For the point indicated by the green dot and located within the cold object, only LORs which lie between the solid green lines contain attenuation information. This is the case for, e.g., the three LORs represented by the dashed lines
