Arab Board Radiology Part 1 Practice Questions - Arab Board Diagnostic Radiology Part 1 Written Exam (ABHS) Exam - Arab Board Radiology Part 1 Practice Questions - Arab Board Diagnostic Radiology Part 1 Written Exam (ABHS) Exam

Question 1

In a diagnostic X-ray tube, what is the primary source of the electrons that are accelerated toward the anode to produce X-rays?

Thermionic emission from the heated filament of the cathode Photoelectric absorption within the anode target Beta decay of the tungsten target material Ionisation of the air gap between cathode and anode

Correct Answer:

Thermionic emission from the heated filament of the cathode

Question 2

Increasing the kVp (peak kilovoltage) applied across an X-ray tube primarily affects the beam in which way?

It increases only the number of photons without changing their energy It increases both the maximum and average energy (penetrating power) of the X-ray photons It has no effect on photon energy, only on tube current It reduces the average photon energy while increasing quantity

Correct Answer:

It increases both the maximum and average energy (penetrating power) of the X-ray photons

Question 3

The product of tube current and exposure time (mAs) in plain radiography most directly controls which property?

The penetrating power of the beam The number of X-ray photons produced (radiation quantity) The half-value layer of the beam The focal spot size

Correct Answer:

The number of X-ray photons produced (radiation quantity)

Question 4

Characteristic X-rays are produced in an X-ray tube when:

An incident electron is decelerated by the nucleus of a target atom An inner-shell electron of a target atom is ejected and an outer-shell electron fills the vacancy A photon undergoes Compton scattering in the patient The filament emits electrons by thermionic emission

Correct Answer:

An inner-shell electron of a target atom is ejected and an outer-shell electron fills the vacancy

Question 5

Bremsstrahlung (braking) radiation in an X-ray tube is produced by which interaction?

An outer-shell electron filling an inner-shell vacancy Deceleration of high-speed electrons as they pass near the nuclei of target atoms Pair production within the anode Coherent scattering of photons in the collimator

Correct Answer:

Deceleration of high-speed electrons as they pass near the nuclei of target atoms
