[Gate-users] voxelised phantom

[Dr.ssa Roberta Matheoud]

Hi,

 

I am trying to define a voxelised phantom and I need to set the range of the materials that are present in my phantom.

How shall I define the attenuation ranges of the materials ? To follow the example shown in Clermont-Ferrand last month:

 

range 0: imagevalue in [0,1000] à material 1

range 1: imagevalue in [1001, 2800] à material 2

range 2: imagevalue in [2801, 9000] à material 3

 

Does the value in brackets are the HU of my TC file ? If so, how shall I translate this information in the *.dat file ?

Moreover, if a new material has been added in the GateMaterial.db file, this is enough for the range translator ? Does it already knows it or it should be defined somewhere else ?



Thanks,



Roberta
