How is the source-to-object distance calculated? By subtracting the OID from the SID SOD = SID - OID. What is Intrinsic Unsharpness? Intrinsic unsharpness refers to the loss of recorded detail due to the use of intensifying screens. WebThe size of the X-ray tube focal-spot and the magnification factors, namely the source-to-specimen and specimen-to-detector distances, are used to calculate the geometric unsharpness of the inspection setup. Geometric unsharpness (Ug) is determined as follows: U g = f b a U_g=f\frac{b}{a} f = X-ray generator focal-spot size. simple house floor plan with dimensions
