[Gate-users] FW: LET problem in GATE

[Klára Badraoui Čuprová]

Dear,

I am medical physicist in Proton Therapy Center in Czech and I am concerned with Monte Carlo simulations in GATE for proton therapy.

I calculate dose and LET distributions in patients and in some patients I get strange results for LETdistributions. (Dose distributions are all OK.)

In some LET distributions a line pattern appears (I am attaching printscreen). (The patients with such problem are irradiated from main angles (0°,90° or 270°).

Calculation of LET to water phantom was OK. May there be some artefact because of calculation grid and phantom voxel size? Calculation grid is 2mmx2mmx2mm.

Voxel phantom of one particular prostatic patient is of size 1.2695mm, 1.2695mm, 2mm. Please, do you have some idea why this happens?

I would be very grateful for help.

Best regards,

Klára Badraoui Čuprová
