Images showing the outcomes of the optimization process of the micro-CT scanning parameters. From top to bottom, the investigated parameters were 80 kV, 200 μA, 100 kV, 100 μA and 150 kV, 70 μA. The set of values 150 kV, 70 μA was chosen because the peak corresponding to the metal (yellow arrow) in the voxel count histogram was higher compared to the same peak in the plots related to the other set of parameters. A higher peak suggested a better separation between voxels belonging to the background (air) and voxels belonging to the material. The reconstructed volume obtained with the values 150 kV, 70 μA provided a clearer representation of the implant compared to the others
