DAVIES SPI REVIEW 2026 1704 QUESTIONS
WITH CORRECT ANSWERS DETAILED
REVIEW MATERIAL GRADED A+
⩥ What is a color flash artifact?
Answer: An artifact in ultrasound imaging that appears as a color signal
in areas where there is no true flow, often caused by motion or tissue
harmonics.
⩥ What are wall filters?
Answer: Filters used in Doppler ultrasound to eliminate low-frequency
noise and artifacts from the signal, enhancing the detection of true blood
flow.
⩥ What techniques are used to demonstrate deep flow in sonography?
Answer: Techniques such as using lower frequency transducers,
adjusting the Doppler angle, and optimizing gain settings to visualize
blood flow in deeper structures.
⩥ What is the purpose of Doppler ultrasound?
Answer: To measure and visualize blood flow and velocity within blood
vessels by analyzing the frequency shifts of ultrasound waves reflected
from moving red blood cells.
