Figure 1A-D Connectivity list files contain the topology of triangular surface mesh elements for Subjects 1, 2, 3 and 4. Points files contain x, y and z values of the mesh vertices in mm Subjects 1, 2, 3 and 4. Figures 2A-L Column 1: Frequency (Hz) Column 2: Low-attenuation SPL (dB re 1 Pa) Column 3: High-attenuation SPL (dB re 1 Pa) Figures 3A-C and 3G-I data files contain the SPL re 1Pa at the vertices of the surface meshes of the 3 key anatomical groups (abdomen, spine, uterus).
