Poly mesh model for the outersurface of Rando® physical phantom was developed
using VTK—software.—Two approaches were adoptedio adjust this model for
purpose of radiotherapy virtual planning. In the first approach we divide surface of
the model to parts, then we modify these parts according to data of target body. In
the second approach we modify the surface as all due to acquired contours of
target body. A strategy was suggested to combine the two approaches depending
on the shown Result.
