how to config laminography(oblique ct)case data generation at yml file ?

[hws203]

@caiyuanhao1998 Could you guide me how to config below yml file contents for my oblique ct case(40 degree) data generation? I can not see any oblique angle degree at your yml config file.

It seems that you just need to input these parameters into the data generation config file (.yaml) in SAX-NeRF/dataGenerator/raw_data/aneurism/config.yml and then execute my data generation script.

@caiyuanhao1998 If i use your script then the prj image looks different from a real one. Coz it is oblique projection(40 degree).

Could you please show it?

1. simulation projection image

   

2. real projection image

3.Below is volume image with z-axis and x-axis

It seems that you did not align the CT volume. Try to adapt some parameters and visualize the projections for debugging

@caiyuanhao1998 I adapted some config param for data generation, and I can see a little better projection which looks more similar to a real one. But there are still some gap as like it is projected on the standard cone beam geometry not laminography. Below are the second project images.

@caiyuanhao1998 Should I tilt the volume image for laminography(tilt=40, degree) ?

@caiyuanhao1998 Below is my test run result, it looks too low SSIM score(0.358). Could you give why this result happens ?

I used customer data with your own data generation script and your train/test too.
