<p class="MsoNormal">Hi Sadek,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is a <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__www.mathworks.com_matlabcentral_fileexchange_72931-2Dderenzo-2Dphantom-2Dvertex-2Dposition-2Dcalculator&d=DwMF-g&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=bODZaHu4t9SeLaNu3e-gcyQNK7Ek7-wqMqF1OzDgM6o&m=Af9p-Mx3v1x0OnvT4bZmWW19mzlHcdAwKlngl8Cn2CY&s=3Z3Dxl9fNA64fcwRxa6Gk6MtQcUUBf9NUGcs40tvYpo&e=">
link</a> to a matlab program that I wrote for calculating the vertex positions of a Derenzo phantom.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">From there, you can define your phantom mac file along the following lines from the quadrant definition:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">/gate/Derenzo/daughters/name hole1<o:p></o:p></p>
<p class="MsoNormal">/gate/Derenzo/daughters/insert cylinder<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/setMaterial material<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/geometry/setRmin 0. mm<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/geometry/setRmax Radius mm # radius defined in matlab program<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/geometry/setHeight Height mm # user-defined height<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/placement/setTranslation x y z mm # x and y printed from matlab program, user-defined z<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/repeaters/insert quadrant<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/quadrant/setLineNumber N # number of rows in triangular pattern specified in matlab program<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/quadrant/setOrientation theta deg # angular orientation defined by direction of line repetition<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/setCopySpacing 4xRadius mm # matlab program assumes space between holes and diameter of holes are equal<o:p></o:p></p>
<p class="MsoNormal">/gate/hole1/quadrant/setMaxRange xx mm # define max range to remove corner-copies of holes falling outside of your Derenzo volume<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You can then repeat this for each triangular region in your phantom macro file. I don’t not have a specific configuration for the source macro, but you should be able to extract/extend what you need from this approach. Let me know if you
have any questions.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">HTH,<o:p></o:p></p>
