In the example figures above, the witdh is vertical because the test object is rotated by 90°

From the dimensions of the two fields (X-Ray and Light) the two differences of width and height are calculated. The difference has a sign: negative values mean that the X-Ray field is smaller than the light field.


Fields width difference = :$ W_X - W_L $

Fields height difference = :$ H_X - H_L $


where:

$ W_X $ = Width of the X-Ray field
$ W_L $ = Width of the light field
$ H_X $ = Height of the X-Ray field
$ H_L $ = Height of the light field
