If an x-ray of the sternum measures 9 cm while the actual sternum measures 6 cm, what is the magnification factor?

To determine the magnification factor in the context of radiography, the formula used is:

Magnification Factor = Size of the Image / Actual Size of the Object

In this case, the size of the image of the sternum as measured on the x-ray is 9 cm, while the actual size of the sternum is 6 cm. Plugging these values into the formula provides:

Magnification Factor = 9 cm / 6 cm = 1.5

This indicates that the image is 1.5 times larger than the actual size of the sternum. The magnification factor is critical in radiography as it helps understand the scale of an image in relation to the real object, allowing radiologic technologists to correctly interpret images and assess structures. In this instance, recognizing that the image is larger (1.5 times) than the actual dimension accurately reflects the magnification occurring in the imaging process.
