STLs derived from CT images of one patient reconstructed at different mAs (a, b, 100 and 50 % radiation dose, respectively, using the AIDR3D reconstruction algorithm). A portion of the mandible is highlighted in pink and the volume enclosed by the STL for that portion is shown in the inset from a superior-to-inferior view. Topologic subtraction of the 50 % dose volume is performed to yield the residual volume, i.e., the physical volume occupied by either the 100 or 50 % dose STL but not the other (c)
