What magnification modes are available if you have a 16" image intensifier?

The 16-inch image intensifier provides various magnification modes that are typically based on the design and operational capabilities of fluoroscopy equipment. When discussing magnification, it is essential to understand that this process enhances the image while narrowing the field of view, which results in increased resolution of the area being examined.

The available magnification modes are selected to optimize the balance between detail and field size. For a 16-inch image intensifier, the magnification options are commonly achieved by selecting specific diameters. The appropriate diameters listed in the correct answer reflect the logical choices for magnification based on standard practices in fluoroscopy.

The values 12, 9, 6, and 4.5 inches represent practical and commonly used settings that would typically allow for effective imaging while utilizing a 16-inch image intensifier. Each of these settings corresponds to a reduction of the field of view and an increase in the magnification factor, providing the necessary detail required for diagnostic procedures.

In contrast, the other choices include less conventional or non-standard sizes for a 16-inch image intensifier, which may not align with the commonly accepted settings utilized in clinical environments, resulting in their exclusion from the correct answer. Thus, the answer of 12, 9
