Fig. 1From: 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 imagesSingle axial slice of the clinical acquisition (100 % radiation dose) reconstructed with AIDR3D for one patient showing the disk-shaped ROI (7.49 mm radius circle shown in red) used for SNR measurement in the levator scapulae muscle. The ROI was identically replicated using software to the remaining 9 radiation dose/reconstruction algorithm configurationsBack to article page
