The cathode is a filament composed of
- Gold
- Silver
- Tungsten
- Copper
Correct Answer

A. Tungsten

Explanation

Tungsten is the correct answer because it is commonly used as the filament in cathodes. Tungsten has a high melting point and excellent heat resistance, making it suitable for withstanding the high temperatures generated in cathode filaments. Additionally, tungsten has a low vapor pressure, which means it does not easily evaporate and degrade the performance of the cathode over time. Therefore, tungsten is the preferred choice for cathode filaments in various applications such as incandescent light bulbs and electron guns in vacuum tubes.

Proper collimation for the film size and target film distance will
- Increase the kvp
- Decrease the wavelength
- Decrease the radiation received by the patient
- Increase the wavelegh
Correct Answer

A. Decrease the radiation received by the patient

Explanation

Proper collimation for the film size and target film distance will decrease the radiation received by the patient. This is because collimation helps to limit the size of the x-ray beam to match the size of the film being used, reducing unnecessary exposure to radiation for the patient. By narrowing the beam, collimation also helps to reduce scatter radiation, further decreasing the radiation dose received by the patient. Therefore, proper collimation is crucial in ensuring patient safety during radiographic procedures.
