Hello everyone,

I am simulating Orthogonal X-ray Projection, specifically Digitally Reconstructed Radiographs (DRR), from a particular CT volume.

To accomplish this, I first created a CT volume and then used the "generateOptimizedXrayProjections" function to produce DRR for both the anteroposterior (AP) and lateral projections.
1. To view the results from this process, please refer to lines 34-35 and line 53. When I run this simulation, I can see the DRR results.
2. However, when I used a real CT image (lines 38-39 and line 54), the generated DRR appeared completely dark.

My goal is to generate a DRR from a real CT image, such as CT_13.nii.gz.

I would greatly appreciate any insights or suggestions regarding this code.

Attached below are the MATLAB code (zip file) for reference.
