[CTSim-Users] X-ray Energy Spectrum

[joseben2 at hotmail.com (jose ben)]

Is there any software documentation that could help in implementing new 
code?

The outline of the major changes for multi-energy transport is:
1. Include attenuation coefficients for all materials of interest as a 
function of energy
2. Enable the capability of including x-ray spectra; a simple method would 
be through a file
3. Loop over energies for each path length of a beamleat or loop over the 
energies for every beamlet for all path lengths and compute transmission. 
The first is more efficient because the path length does not need to be 
computed everytime. The second is easier to implement and has the advantage 
of providing the transmitted spectra, which would be useful to compute 
detector efficiency and statistics.

Based on the current implementation of the code, could anybody please 
provide some high-level instructions that could help in implementing the 
code?

Scattering is a much more complex effort beyond this scope. Statistics is 
much simpler and can be added later.

Thank you.
