Algorithm 1 Conversion of CBCTimages to X-ray Images

1.  Input: 3D cone beam CBCTdataset

2.  Output: X-ray images

3.  Begin

4.$X\_ray\_dataset$ = [ ] // empty dataset

5.  for all $img$ in dataset do:

6.    if image_quality is poor Then:

7.$valid\_dataset$ = $RemoveImage\left(img\right)$

8.    else:

9. $SaveImage( )$ // save images as DICOM

10.$RecoImage( )$ // reconstruct images using C.S. 3D Imaging Software

11.$SliceImage\left(img\right)$ // slice images

12.$X\_ray\_dataset=SaveImg(img$) // Save images as PNG format

13. end for

Return X-ray images
