Regarding bremsstrahlung X-rays produced in an X-ray tube:
It is produced from the interaction of electrons with the nucleus of the target atom.
The energy spectrum is discrete.
The lower-energy photons are absorbed by the tube.
The maximum energy of the photons is equal to the tube kVp.
It is the major component of photons produced from a tungsten target.
The heel effect is
due to attenuation of X-rays in the target material.
greater on the cathode side of the X-ray field.
bigger for a smaller anode angle.
more pronounced at lower kVp.
useful in spine radiographs.
Regarding x-ray:
It is produced from the interaction of electrons with the nucleus of the target atom.
The energy spectrum is continuous.
The x-ray production process does not result in any heat.
The maximum energy of the photons is equal to the tube kVp.
It is emitted from a metastable radioisotope.
Which of these is NOT true about the x-ray tube for production of x-ray?
a vacuumed glass tube is used to prevent electron from hitting the air molecules.
the cathode consists of heated filament with high ionization energy.
cooling system is required at the anode metal target in order to prevent the metal from melting
the metal target of anode should be metal with high melting point.
Rearrange these statements to describe the production of x-ray:
I. The high speed electrons rapidly decelerated on the impact, and x-rays are emitted.
II. The high voltage current supply heat the filament cathode (to emit electrons at high acceleration).
III. Electrons emitted are accelerated towards a metal target.
I, II, III

II, III, I
II, I, III
