We are trying to convert 3D volumetric CT images to chest Xray (for a sake of comparison with another dataset). We use this example:
The projection results in radiography-looking images but it is visually different from what we expected. Here is an example of what we get:
and example what we thought we can get:
I think we are missing some transformation on intensity right before the projection and I don’t what should be. I searched for it and I found this paper:
Is there any transformation on the intensity of 3D CT image that results in 2D projection looking more like chest Xray? Is there anything like that paper implemented in ITK?
Also, if someone can provide some insight into how to use the available options with the GetDRRSiddonJacobsRayTracing method.
