Question

Identify which of the following will produce an increase in scatter radiation production:

1. use of lower kVp
2. use of a smaller collimated feild size
3. use of a larger collimated feild size
4. increase the amount of tissue compression being used

Answer 1

Option C isz the answer.Increasing scatter radiation production is influenced by factors like x-ray energy and field size. Of the provided options, using a larger collimated field size will produce an increase in scatter radiation.

Step-by-step explanation:

The production of scatter radiation increases with factors that lead to more interactions between x-rays and atoms within a given material. Factors that influence this include the energy of the x-rays, the size of the collimated field, and the density of the material.

Regarding the options provided:

1. Using a lower kVp (kilovolt peak) decreases the energy of the x-rays, leading to increased absorption and therefore a decrease in scatter radiation.
2. Using a smaller collimated field size limits the volume of tissue irradiated, reducing the total number of interactions and thus decreasing scatter radiation.
3. Use of a larger collimated field size increases the volume of tissue exposed, which increases the potential for interactions and thus increases scatter radiation production.
4. Increase the amount of tissue compression reduces the volume of tissue through which x-rays need to pass, thus leading to less scatter radiation production.

Therefore, to answer the student's question, option 3, the use of a larger collimated field size, will produce an increase in scatter radiation production.
