Question 66/99

Which adjustment will reduce the appearance of posterior shadowing artifact?

A. Increasing spatial compounding

B. Decreasing dynamic range

C. Decreasing the number of focal zones

D. Increasing persistence

Correct Answer: A

Comprehensive and Detailed Explanation From Exact Extract:
Spatial compounding uses multiple scan angles to create an image. By combining information from different angles, it can reduce shadowing artifacts caused by highly attenuating structures.
According to sonography instrumentation reference:
"Spatial compounding reduces artifacts such as posterior shadowing by averaging images acquired from multiple insonation angles." Therefore, the correct answer is A: Increasing spatial compounding.
