Comparison between CTtissue&air and the pseudo-CT studies CTConoProbe and CTArtec in both configurations (with and without blood). In this figure, each pseudo-CT study (tissue depicted in orange colour) was superimposed on CTtissue&air (tissue represented in white colour). In all cases, air was depicted in black colour. Therefore, tissue in the pseudo-CT study matches that in CTtissue&air when orange and white colours overlap. On the other hand, air in the pseudo-CT study matches that in CTtissue&air when black colour is shown in the figure. Other options represent mismatches. From left to right in each configuration, sagittal, coronal and axial views. The red arrows point to a deep hole not completely scanned
