Q1 QUESTION 1 OF 963
What side of the x-ray tube positive
CORRECT ANSWER
Anode
RATIONALE
The anode is the positively charged electrode in an x-ray tube, facilitating the acceleration of electrons from the
cathode and enabling x-ray production upon their interaction with the target material. This fundamental principle of
electron dynamics governs the functioning of x-ray imaging systems.
Q2 QUESTION 2 OF 963
What side of the x-ray tube is negative
CORRECT ANSWER
Cathode
Page 2
, RATIONALE
The cathode is the negative side of the x-ray tube, where thermionic emission occurs, releasing electrons that are then
accelerated toward the anode. This process is fundamental to x-ray production, as the interaction of high-energy
electrons with the anode generates x-rays.
Q3 QUESTION 3 OF 963
What is the role of the glass envelope
CORRECT ANSWER
Containment and maintains the vacuum
RATIONALE
The glass envelope serves to contain the thermal energy produced during electron interactions while maintaining a
vacuum, which is essential for efficient electron flow and preventing oxidation of internal components. This design
minimizes energy loss and enhances the longevity and performance of the device.
Q4 QUESTION 4 OF 963
What is the role of the tube housing
CORRECT ANSWER
Prevents leakage and insulates
RATIONALE
Tube housing functions to contain radiation produced during x-ray generation, preventing leakage that could expose
personnel and patients to harmful doses, while also providing thermal insulation to maintain optimal operating
temperatures for the tube. This dual role is critical for safety and efficiency in radiological practices.
Q5 QUESTION 5 OF 963
What end of the tube has the filament and focusing cup
CORRECT ANSWER
Cathode
Page 3
, RATIONALE
The cathode contains the filament and focusing cup, which are essential for thermionic emission, where the filament
heats up to release electrons. This process is critical for generating the electron beam in x-ray production within the
tube.
Q6 QUESTION 6 OF 963
What are the types of anodes
CORRECT ANSWER
Rotating and Stationary
RATIONALE
Anodes are classified based on their operational mechanics; rotating anodes enhance heat dissipation and image
quality by distributing electron bombardment over a larger surface area, while stationary anodes are simpler in design
and suitable for lower-power applications. Understanding these distinctions is crucial for optimizing radiographic
techniques and equipment selection in medical imaging.
Q7 QUESTION 7 OF 963
What is the anode made of
CORRECT ANSWER
Tungsten
RATIONALE
Tungsten's high atomic number and melting point make it ideal for anodes in x-ray tubes, allowing for efficient electron
bombardment and heat dissipation. This property is critical for maintaining structural integrity during high-energy
radiation production.
Q8 QUESTION 8 OF 963
Why is Tungsten the chosen material for the anode
CORRECT ANSWER
Has a high atomic number meaning it has a high melting point
