Final answer:
In magnification radiography with an SID of 40 inches and an OID of 6 inches, the magnification of the object is approximately 1.18 times.
Step-by-step explanation:
When performing magnification radiography, the magnification (M) of the object can be determined using the formula: M = SID / (SID - OID). In this case, the Source-to-Image Distance (SID) is 40 inches, and the Object-Image Receptor Distance (OID) is 6 inches. By substituting these values into the formula, we get M = 40 / (40 - 6) = 40 / 34. Hence, the magnification of the object is approximately 1.18 times.
To calculate the magnification of an object in magnification radiography, you can use the formula:
Magnification = SID / OID
where SID represents the Source-to-Image Distance and OID represents the Object-Image Receptor Distance.
In the given scenario, the SID is 40" and the OID is 6". Plugging these values into the formula, we get:
Magnification = 40" / 6" = 6.67
Therefore, the magnification of the object is 6.67.
