I would like to understand if it is possible to import an image into FLUKA, in order to generate a spatial distribution of a radionuclide that closely reflects reality. The goal is to emulate the workflow used for DICOM images in medical applications, but using other image formats in a non-medical context.
Could you advise me on the possible approach to follow?
Thank you in advance for your guidance.
Input files
Please upload all relevant files. (FLUKA input file, Flair project file, user routines, and data files)
It would be very useful if you could elaborate a bit on what you are trying to to achieve exactly. If I understand correctly, you would like to simulate radianuclides distributed according to a DICOM image showing the concentration of the aformentioned radionuclide?
If this is the case, I think that the easiest way would be to extract the information in a text file format and translate it for example with a python script into a particle distribution which could be loaded with the user source routine.
I would be happy to help, but I need a bit more details and maybe an example file that you would like to work with.
Hi Jerzy Mikolaj Manczak,
Thank you for your reply.
I have a sample which is a mixture of two phases and one of these phases is my source, the other phase is the target.
Now I have an auto-radiography image and I could create a Raman image.
I wanted to treat the image in order to attribute (with image analysis methods) phase 1 and phase 2 to the two phases, and defining e.g., phase 2 as radionuclide X.
Until now, I have analysed and created a text file which provides 0 for the background, 1 or 2 in each pixel. I am trying to figure out exactly how to progress to the next step.
Thank you again.
Okay, I must admit that I am not very familiar with medical physics terms nor with the DICOM format itself. What does your text file represet? Is it a 3 or 2-dimensional grid with the distribution of the radionuclide? What would you like to happen in FLUKA with any of the given number: background, target or source? You have your geometry let’s say and then you want to place radionuclides according to the distirbution of 2s in space?
In reality my application would be more for a ceramic sample. I would like to calculate the dpa in the phase 2 caused by the radionuclide decay.
Now the image is a 2-D grid. This grid represents the cross-section distribution of the compound containing the radionuclide and the target. Yes, I would like to use the information to reconstruct the sample in 3-D, hence add a third dimension (which I can easily know) , assign radionuclide to the phase 1 and scoring in the phase 2 the dpa.
Best,
Mara
Do you have an example FLUKA file (even simplified or incomplete) or for the moment you just have your DICOM file and the corresponding text file with the grid? I will think about the best approach to tackle your problem and come back to you, but in the meantime, are you aware of the DICOM module of Flair?
It provides an interface between the DICOM format and FLUKA capabilities, maybe it will be able to give you a solution.
