The energy of electrons striking the output phosphor is primarily converted into what type of photons?

When electrons strike the output phosphor in a fluoroscopy system, the energy from these electrons is primarily converted into light photons. This process occurs because the output phosphor, typically made of a material like zinc cadmium sulfide or similar substances, is designed to emit visible light when it absorbs the energy of the incoming electrons.

The fluoroscopic system relies on this conversion to produce a visible image, which is then captured and displayed for diagnostic purposes. The generated light photons are crucial because they significantly enhance the visibility of the images on the monitor, allowing for accurate diagnosis and analysis.

In contrast, x-ray photons are produced during the initial interaction with the input phosphor and are not the result of the output phosphor interaction. Photo-emissions refer to the emission of electrons as a result of interaction with light, which is not the relevant process occurring at the output phosphor. Remnant radiation refers to x-rays that have passed through the patient and contribute to the image but are separate from the light photons generated by the output phosphor.
