How to get forbild head Phantom?

Hi @tianlili1, you can use this code to generate the phantom using MATLAB. To do it you need to clone this repository, or download it as an archive and extract to some directory. Then, you need to run the MATLAB, go to the directory and run the commands as written in the README.md. To get the sinogram, you can use radon function available in MATLAB.

I have downloaded your source code. The document contains a lot of .m files. I don't know which one to run. Can you tell me in detail how to do?

[tianlili1]

Running each .m file will give an error "The number of input parameters is insufficient"

I did it according to the README. The first step to generate phantom was successful, but I was given an error when I ran the second command.

Hi! I still have a question, can I use it to get a .phm file?

Hi @tianlili1, which error does the second command produce?

Hi! I still have a question, can I use it to get a .phm file?

It is the first time I hear about such format. It is possible if there is a function in MATLAB to do that. Otherwise, you need to save the phantom as an image and convert it using third-party software.

Thank you for your reply. I don't know much about this aspect, so I asked some very mentally handicapped questions. Another question is: How can I know the attenuation coefficient of each part of this Phantom?

Hi @tianlili1, for the physical values please check the original paper (Figure 1 + Section 4.1). It corresponds to the Matlab file physical_value.m. If you need only intensities of the image, you can use unique function and then apply some thresholding method to see the structures with given intensity.

Ok，I have read the paper you wrote,Thank you for that!
