Explanation:
The objective lens is an integral part of a light microscope as it provides the viewer with the picture or image of the specimen. There are several types of objective lens depending on their magnification.
The lowest possible objective lens with the power of 4x is called the SCANNING OBJECTIVE. In combination with the eye/occular lens, it provides a magnification of 4x × 10 = 40x. The name of this lens comes from the fact that it provides a full scan of every part of the specimen being viewed before diversifying into a specific region by changing the objective.

though; bone scan is not specific for fracture but still most useful in
detecting occult rib fractures.
