Question

By definition, the increase in brightness or intensity due to minification gain is:

1. the compression of electrons produced by the input screen onto the output phosphor
2. an increase in the number of x-ray photons making up the image
3. the additional energy when accelerating the electrons
4. an improvement in the quality of x-ray photons making up the image

Answer 1

Minification gain refers to the increased intensity of an image that occurs when the same number of electrons from a larger area (input screen) are compressed onto a smaller area (output phosphor).

Step-by-step explanation:

By definition, the increase in brightness or intensity due to minification gain is the compression of electrons generated by the input screen onto a smaller output phosphor. This compresses more electrons into a smaller area without reducing their number, thereby increasing the image's brightness per unit area.

While minification gain does increase the visible output, it should not be confused with an increase in the number of x-ray photons or their quality, nor does it involve additional energy in accelerating the electrons.

The increase in brightness or intensity due to minification gain is an increase in the number of x-ray photons making up the image. When a beam of X-rays strikes a crystal, the rays scatter in all directions by the atoms within the crystal. When scattered waves traveling in the same direction encounter one another, they undergo interference, resulting in an increase in the intensity of the image.
