4DCT 4

Surface renderings of the inhale lung volume are shown, overlain with displacement vectors (T00 --> T50) for each of the validation landmarks. All surface renderings were generated in the MATLAB (Mathworks, Sunnyvale, CA) environment.

Cine loops through representative axial, coronal, and sagittal sections are also available here.
