Figure 4

Illustration of the effect of varying CNN components and configurations of the representing case in coronal view. CTPM was generated using the proposed setting. The following CTPMs were generated in different CNN components and configurations: ROI.—remove ROI attention module, Skip.—remove skip attention module; Res.—remove residual module; ReL. – use ReLU instead of PReLU; LRe. – use LReLU instead of PReLU; wid.—with CNN width of 3, 4, or 5 times; dro—with a dropout rate of 0, 0.2, or 0.3; ker 3×—use kernel size of 3 × 3 × 3 install of 5 × 5 × 5.
