ANSWERS GRADED A+

⩥ what is required too make a xray? Answer: Source of electrons
(cathode)
Acceleration (high voltage)
Sudden stop (anode)


⩥ how much energy is used to produce the xray? Answer: about 1
percent!
the other 99 scatters and is just heat


⩥ What's a cathode? Answer: - Negative electrode
- Produces electrons
- In the filament


⩥ What's an anode? Answer: - Positive electrode
- Target for electrons
- Converts kinetic energy into x-rays


⩥ diffrence between cathode and anode? Answer: Cathode:

, • Negative electrode
• Contains filament
• Produces electrons via thermionic emission (boiling off electrons)
Anode:
• Positive electrode
• Target for electrons
• Converts kinetic energy into x-rays


⩥ what are the steps for a xray being produced? Answer: High voltage
accelerates electrons --> Electrons strike anode --> Sudden deceleration
creates x-rays + heat --> X-rays exit via collimator (controls beam size)


⩥ what are the advantages of digital radiography? Answer: Fast image
acquisition
Post-processing capability
No need to re-expose patient (as often)
Easy storage and sharing


⩥ what does the imaging plate do? Answer: it serves as a background to
capture your xray and stop the beam at your intended target/bodypart


⩥ what is the Immediate image display Answer: - instant rendering of
visual data on a screen
