X-Ray System Components and Functions

The video tutorial explains the structure and function of an X-ray tube, highlighting its components such as the glass envelope, cathode, and anode. It describes the process of electron emission and X-ray production, including the photoelectric and BM strolling effects. The tutorial also covers modern X-ray tube designs with rotating anodes for better heat management. It discusses the types of radiation, filtering methods, and the importance of grids and screens in improving image quality while ensuring patient safety.

What is the primary material used for the cathode in an x-ray tube?

• Aluminum

• Tungsten

• Copper

• Lead

What is the main purpose of the glass envelope in an x-ray tube?

• To provide a vacuum environment

• To cool the tube

• To conduct electricity

• To enhance x-ray production

What happens when electrons strike the anode in an x-ray tube?

• They create magnetic fields

• They generate heat and x-rays

• They produce sound waves

• They emit visible light

What percentage of energy is converted into x-rays when electrons hit the anode?

• 10%

• 50%

• 99%

• 1%

Why is a rotating anode used in modern x-ray tubes?

• To enhance image quality

• To decrease electron speed

• To reduce heat generation

• To increase x-ray production

What type of radiation is stopped after reaching the patient and does not form an image?

• Gamma radiation

• Type B radiation

• Ultraviolet radiation

• Type A radiation

What is the function of a filter in an x-ray machine?

• To block high-energy waves

• To remove low-energy radiation

• To increase radiation exposure

• To enhance image contrast

What is the purpose of the grid in an x-ray system?

• To allow only straight x-rays to pass

• To increase radiation exposure

• To block all x-rays

• To enhance the speed of x-rays

What material is the screen in an x-ray system typically made of?

• Copper

• Calcium Tungstate

• Silver promite

• Lead

How does the grid improve the quality of an x-ray image?

• By allowing only straight x-rays to pass

• By blocking all radiation

• By enhancing the color of the image

• By increasing the speed of x-rays
