Algorithm 2.

Statistical analysis of dose distribution on body area.

Input: Dose distribution UV, triangulated 3D body model $G$

Loop: Face $f_i$ in $G$

$A(i)=\text{area}[f_i(1),f_i(2),f_i(3)]$

$D(i)=\text{mean}\{UV[f_i(1)],UV[f_i(2)],UV[f_i(3)]\}$

end Loop

Output:$\mathbf{A}$ as the arrays of area for all faces, $\mathbf{D}$ as the dose value for all faces.
