[Gate-users] Gate-users Digest, Vol 84, Issue 24

[zhihuaigu]

define a daughter of the solid polyethylene cylinder and the material of the daughter to be air.

this is the sample code, the placement of the daughter should be the relative coordinate.

/gate/world/daughters/name breastPhantom
/gate/world/daughters/insert cylinder
/gate/breastPhantom/geometry/setRmin 0. mm
/gate/breastPhantom/geometry/setRmax 55. mm
/gate/breastPhantom/geometry/setHeight 11.0 mm
/gate/breastPhantom/placement/setTranslation 0. 0. 0. mm
/gate/breastPhantom/setMaterial Breast
/gate/breastPhantom/vis/setColor cyan
# 10mm air
/gate/breastPhantom/daughters/name microcacification
/gate/breastPhantom/daughters/insert cylinder
/gate/microcacification/geometry/setRmin 0. mm
/gate/microcacification/geometry/setRmax 10. mm
/gate/microcacification/geometry/setHeight 11.0 mm
/gate/microcacification/placement/setTranslation 30. 0. 0. mm
/gate/microcacification/setMaterial Air
/gate/microcacification/vis/setColor yellow
/gate/microcacification/vis/forceSolid
