Question

The X-ray beam leaving the x-ray tube toward the patient is ________.

A) Primary beam
B) Scatter beam
C) Remnant beam
D) Secondary beam

Answer 1

The X-ray beam leaving the X-ray tube toward the patient is known as the 'Primary beam'.

Step-by-step explanation:

The X-ray beam leaving the X-ray tube toward the patient is known as the Primary beam. This is the initial beam of radiation that originates from the X-ray tube and has not interacted with any material or tissue yet. The term 'scatter beam' refers to X-rays that have been deflected from their original path after interacting with matter. The 'remnant beam' describes the X-rays that emerge after passing through the patient's body and carry the diagnostic information to the imaging detector. Lastly, the 'secondary beam' is generally used to refer to radiation that arises from interactions, such as scatter or secondary emissions, but is not the original radiation emitted from the X-ray tube.
