ARDMS Sonography Principles and Instrumentation Sample Questions (Q192-Q197):

NEW QUESTION # 192
Which change would lead to a reduction in frame rate?

A. Increasing the pulse repetition frequency (PRF)
B. Decreasing the depth
C. Increasing the number of focal zones
D. Decreasing the sector width

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Each additional focal zone requires extra transmissions per scan line, which slows down frame acquisition, thereby reducing the frame rate.
Principles and Instrumentation state:
"Increasing the number of focal zones lowers frame rate because multiple pulses are needed per scan line for each focal depth." Increasing PRF (B) allows faster data acquisition.
Decreasing depth (C) shortens round-trip time, increasing frame rate.
Decreasing sector width (D) reduces scan lines, increasing frame rate.

NEW QUESTION # 193
What is the most effective way to reduce aliasing on color Doppler?

A. Decrease pulse repetition frequency (PRF)
B. Increase wall filter
C. Decrease wall filter
D. Increase pulse repetition frequency (PRF)

Answer: D

Explanation:
Aliasing in color Doppler occurs when the velocity of blood flow exceeds the Nyquist limit, which is half the PRF. To reduce aliasing, the PRF must be increased. This raises the Nyquist limit, allowing higher velocities to be measured without wrapping around the baseline. Increasing PRF reduces the occurrence of aliasing artifacts by expanding the range of detectable velocities before aliasing occurs.

NEW QUESTION # 194
Which transducer was most likely used to create this image?
A ultrasound of a fetus Description automatically generated

A. Curvilinear
B. Phased array
C. Endocavity
D. Linear array

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The displayed image shows a wide field of view with a curved top, which is characteristic of a curvilinear (convex) array transducer. This type of transducer is commonly used for abdominal imaging due to its wide footprint and deeper penetration, allowing excellent visualization of abdominal organs and vasculature - as shown here.
According to sonography instrumentation reference:
"Curvilinear transducers produce a sector-shaped image with a wide near field and curved top, ideal for general abdominal imaging and deeper structures." Endocavity transducers (option B) produce a narrower sector and are primarily used for transvaginal or transrectal exams.
Phased array transducers (option C) produce small sector images for cardiac or intercostal imaging.
Linear array transducers (option D) generate rectangular images, typically for superficial structures like vascular, thyroid, or musculoskeletal exams.
Therefore, the correct answer is A: Curvilinear.

NEW QUESTION # 195
Which transducer was most likely used to create this image?

A. Curvilinear
B. Phased array
C. Endocavity
D. Linear array

Answer: A

Explanation:
The image shown is typical of an abdominal ultrasound, which commonly utilizes a curvilinear transducer. Curvilinear transducers have a wider field of view at depth, making them ideal for imaging large structures within the abdomen. These transducers emit a curved beam, allowing for better penetration and a broader field of view, which is necessary for comprehensive abdominal examinations. The curvature of the image, the wide field of view, and the depth of penetration all suggest the use of a curvilinear transducer.

NEW QUESTION # 196
What is a potential negative consequence of using a high wall filter?

A. Penetration is reduced
B. Too much noise may appear on the image
C. Desired signal may be eliminated
D. Aliasing could occur

Answer: C

Explanation:
A high wall filter is used in Doppler ultrasound to eliminate low-frequency signals that may be attributed to vessel wall motion or other low-velocity flows. However, if the wall filter is set too high, it can inadvertently eliminate desired low-frequency Doppler signals that represent real blood flow, particularly in smaller vessels or those with slower flow velocities. This results in a loss of valuable diagnostic information.
