What is the location of the focal spot during normal mag mode?

In normal magnification mode, the focal spot is typically closer to the output phosphor. This positioning enhances image resolution and detail, which is particularly important during fluoroscopy procedures. When the focal spot is nearer to the output phosphor, it allows for greater image clarity and reduces the amount of scatter radiation that can degrade the quality of the image. The magnification mode increases the size of the input image, resulting in a more detailed display on the output phosphor. Since the image being displayed on the monitor is taken at a magnified scale, the location of the focal spot plays a critical role in ensuring the fidelity of the image captured from these intensified displays.

Other options either misrepresent the relationship between the focal spot and output/input phosphors or suggest a position that would not optimize image quality in magnification mode.
