[Gate-users] Voxelized source and phantom in benchImageNavigators

[Emilie Gaudin]

Dear Zhengzhi ,

You are right saying the documentation about voxelized phantom is deprecated, especially for image insertion.
Here is some working code for a typical phantom. Be careful of the path in your code and in your image header and everything should be fine.

However, I cannot answer for the visu.

Cheers,

Emilie

Objet : [Gate-users] Voxelized source and phantom in benchImageNavigators

Dear Han Gyu, Howard, and Gate users,

(I noticed from the previous emails that you two are using voxelized source and phantom, thus I send this email to you. )

I tried to import voxelized source and phantom in PET GATE simulation by following the benchImageNavigators<https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FOpenGATE%2FGate%2Ftree%2Fdevelop%2Fbenchmarks%2FbenchImageNavigators%2Fpet&data=02%7C01%7CEmilie.Odette.Gaudin%40USherbrooke.ca%7C5a0fdfecb92f41327dee08d7bb181412%7C3a5a8744593545f99423b32c3a5de082%7C0%7C0%7C637183584400280037&sdata=EWD5fXak7Z6BJEkq10UUv3BD%2F4r6eNyw3caHQrS9C7w%3D&reserved=0> example provided in GATE 8.2 package. However, I can't even get example code work. I have two problems with the example code:

  1.  Visualization issue:  the qt viewer would automatically close and leaves me no time to visually check the voxelized source or voxelized phantom;
  2.  Running issue: the example can't run and keep throwing the warning message as shown in the attached screenshot, and no actual output is generated but an empty root file.

I believe importing PET/CT image has become very mature in GATE simulation. Could anyone give any help with running this example code?

I am very appreciative of your help.
Sincerely,

Zhengzhi
