Fig. 6From: The residual STL volume as a metric to evaluate accuracy and reproducibility of anatomic models for 3D printing: application in the validation of 3D-printable models of maxillofacial bone from reduced radiation dose CT imagesResidual volumes resulting from topological subtraction of the STL model derived for each reconstruction/radiation dose configuration from that derived for the reference standard configuration (AIDR3D reconstruction, 100 % dose) in the first (a) and second (b) patient included in this study shown both as an absolute measurement (left y-axis) as well as with respect to the volume of the reference bone STL modelBack to article page
