[Gate-users] Core Dump CT Rotation

[Auranuch Lorsakul]

Sorry, actually the error message looks like this:

	[G4-cerr] ERROR - G4SteppingManager::GetProcessNumber()
	[G4-cerr]         SizeOfSelectedDoItVector= 100 ; is smaller then one of MAXofAtRestLoops= 0

Hi Gate users,

With Gate 6.1, I simulated a CT scanner with a XCAT phantom for 1,000 projection views. I got a core dump error (shown below) after obtaining the projection slice #96. This error does not happen when I use a cylindrical phantom. Does anyone have an idea how to fix this?

The phantom matrix size 512 x 242 x 231, pixel size 1.03 x 1.03 x 0.687 mm

Thanks,
Ney
