ARDMS Sonography Principles and Instrumentation Sample Questions (Q94-Q99):

NEW QUESTION # 94
What causes color flash artifact?

A. Strong reflector
B. High velocity blood flow
C. Tissue motion
D. Aliasing

Answer: C

Explanation:
Color flash artifact occurs due to tissue motion. This artifact is a type of color Doppler artifact that happens when there is movement of tissue or transducer, which causes the Doppler system to incorrectly interpret the motion as blood flow. This results in a flash of color appearing on the image where there is actually no flow. Tissue motion affects the Doppler signal, leading to misinterpretation by the system, and hence the artifact appears as a flash of color.

NEW QUESTION # 95
Which artifact is seen as a result of an increase in echo amplitude in the tissue located distal to an anechoic structure?

A. Comet tail
B. Enhancement
C. Reverberation
D. Mirror image

Answer: B

NEW QUESTION # 96
The calipers in this image measure which performance characteristic of a system?

A. Dynamic range
B. Depth measurement accuracy
C. Axial resolution
D. Lateral resolution

Answer: B

Explanation:
The calipers shown in the image are used to measure the depth of structures within the ultrasound image. This performance characteristic, known as depth measurement accuracy, assesses how accurately the ultrasound system can measure the distance from the transducer to a specific point within the body. Accurate depth measurements are crucial for diagnostic purposes, ensuring that anatomical and pathological structures are correctly identified and evaluated.

NEW QUESTION # 97
What is the effect of an increased aperture in a linear array transducer?

A. Improved axial resolution
B. Shorter near-field length
C. Deeper focus
D. Decreased temporal resolution

Answer: C

Explanation:
The aperture of a transducer is the active area that emits and receives the ultrasound waves. In a linear array transducer, increasing the aperture (using more elements for transmission and reception) results in a deeper focus because the beam is more tightly focused over a longer distance. This improves lateral resolution at greater depths, as the ultrasound beam maintains a narrower width for a longer distance. It allows for better imaging of deeper structures without sacrificing resolution.

NEW QUESTION # 98
Which change was made after acquiring image A to produce image B?

A. Decreased pulse repetition frequency
B. Increased sweep speed
C. Increased spectral gain
D. Decreased wall filter

Answer: A

Explanation:
Increased Sweep Speed: This affects the display of the waveform over time but does not impact the appearance of the spectral Doppler signal in the way shown.
Decreased Pulse Repetition Frequency (PRF): Lowering the PRF can lead to aliasing, which is evident as the waveform wrapping around in the spectral display from image A to image B. This makes the velocity appear higher than it actually is.
Decreased Wall Filter: This adjustment primarily affects the elimination of low-frequency Doppler signals but does not typically cause the kind of changes seen in the images.
Increased Spectral Gain: Increasing the gain would result in a brighter spectral display but not the wrapping of the signal as seen.
