<br>
I think "parallelbeam" collimator construction has not been
working right since Gate v.5.0.0, so the other option is to use
cubicArray and linear repeaters as Giuseppe mentioned. In this
case, the septal thickness is defined implicitly in the two
repeatVectors. For hexagonal shaped holes the second and third
components of the cubicArray repeatVector are:<br>
<br>
Ry = hole_diameter + septal_thickness<br>
Rz = Ry * sqrt(3)<br>
<br>
where hole_diameter is defined across the flat sides. The
corresponding two components of the linear repeatVector are:<br>
<br>
Ly = Ry / 2 <br>
Lz = Rz / 2 <br>
<br>
(the x-components of both repeatVectors are 0). Then the
cubicArray repeatNumberY/Z determine the number of holes in each
direction divided by 2.<br>

<br>
Hello everyone,<br>
<br>
I'm following the user's guide<br>
<a moz-do-not-send="true"
href="http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.2:Defining_a_system"
target="_blank">http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.2:Defining_a_system</a><br>
trying to model a parallel hole collimator.<br>
<br>
The guide shows the following example:<br>
<br>
/gate/SPECThead/daughters/name colli<br>
<br>
#specify that the parallel beam collimator setup
must be used<br>
/gate/SPECThead/daughters/insert parallelbeam<br>
<br>
#set the collimator material<br>
/gate/colli/setMaterialName Lead<br>
<br>
#set the collimator dimensions<br>
/gate/colli/geometry/setDimensionX 70 cm<br>
/gate/colli/geometry/setDimensionY 80 cm<br>
<br>
#set the thickness of the collimator<br>
/gate/colli/geometry/setHeight 3 cm<br>
<br>
#specify the hole radius<br>
/gate/colli/geometry/setInnerRadius 0.5 cm<br>
<br>
#set the septal thickness to the required distance
between the holes<br>
/gate/colli/geometry/setSeptalThickness 0.2 cm<br>
/gate/colli/placement/alignToX<br>
/gate/colli/placement/setRotationAxis 0 0 1<br>
/gate/colli/placement/setRotationAngle -90 deg<br>
<br>
<br>
I'm getting a problem as follows:<br>
<br>
/opt/simulation/gate_v6.2/source/geometry/src/GateVVolume.cc
(l.179): The<br>
material of the volume side hole 1 is not defined.<br>
<br>
Anyone knows how to fix this?<br>
<br>
Thanks,<br>
<br>

I had the same problem and here is how I fixed it<br>
<br>
In the <a moz-do-not-send="true"
href="http://GateConfiguration.h.in"
target="_blank">GateConfiguration.h.in</a> <<a
moz-do-not-send="true"
href="http://gateconfiguration.h.in/"
target="_blank">http://gateconfiguration.h.in/</a>>
file found<br>
within the home folder of Gate, change this line:<br>
<br>
<br>
#cmakedefine GATE_USE_FILE @GATE_USE_FILE@<br>
<br>
<br>
to this:<br>
<br>
#cmakedefine GATE_ANALYSIS_USE_FILE
@GATE_ANALYSIS_USE_FILE@<br>
<br>
<br>
Recompile Gate and it should now work!<br>
<br>
Cheers,<br>

That is an interesting question.<br>
<br>
Could you keep me informed on your findings?<br>
If it isn't already in Gate it should be easy to
add.<br>
Just contact me and I can help you with this or
implement it for you.<br>
