Question

Recorded detail can be improved by decreasing the SID the OID

patient/part motion

A. 1 only
B. 3 only
C. 2 and 3 only
D. 1, 2, and 3

Answer 1

In radiography, recorded detail can be improved by decreasing the OID and reducing patient or part motion, which corresponds to option C: 2 and 3 only. Decreasing the SID would actually reduce recorded detail due to increased magnification and potential for unsharpness.

Step-by-step explanation:

The question concerns the factors that can improve recorded detail in radiographic imaging. Recorded detail refers to the clarity or resolution of the structures shown on the radiograph. To address the question, let's examine each option:

1. Decreasing the SID (Source-to-Image Distance): Decreasing SID actually reduces the recorded detail because it increases magnification and can lead to increased image unsharpness.
2. Decreasing the OID (Object-to-Image Distance): Decreasing OID improves recorded detail because it reduces magnification and decreases the opportunity for motion unsharpness.
3. Reducing patient/part motion: Minimizing or eliminating patient or part motion during the exposure time significantly improves recorded detail by preventing blurring.

Given these considerations, the correct answer to the question is option C: 2 and 3 only.
