ARDMS Sonography Principles and Instrumentation Sample Questions (Q120-Q125):

NEW QUESTION # 120
Which technique uses frame averaging?

  • A. Fusion imaging
  • B. Persistence
  • C. Panoramic
  • D. Elastography

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Persistence is a post-processing technique that averages multiple consecutive frames to reduce random noise and smooth the displayed image. It helps enhance image quality by stabilizing slow-moving or stationary structures while sacrificing some temporal resolution.
As per official sonography Principles and Instrumentation guidelines:
"Persistence is a frame averaging technique that reduces speckle and temporal noise, improving image smoothness by combining data from successive frames."
* Elastography measures tissue stiffness.
* Panoramic imaging extends the field of view.
* Fusion imaging combines ultrasound with other imaging modalities.
Therefore, the correct answer is C: Persistence.


NEW QUESTION # 121
Which target group is used to evaluate transverse distance measurement accuracy in this tissue-mimicking phantom image?

  • A. Option B
  • B. Option C
  • C. Option A
  • D. Option D

Answer: D

Explanation:
In the tissue-mimicking phantom image, Option D (blue box) is used to evaluate transverse distance measurement accuracy. Phantoms are used to simulate human tissue and provide a standardized way to test the accuracy and precision of ultrasound machines. Transverse distance measurement accuracy is assessed by measuring known distances between targets in the phantom. The blue box (Option D) typically contains targets positioned to specifically test the accuracy of transverse measurements, ensuring that the ultrasound system provides reliable and precise distance readings.

NEW QUESTION # 122
Which adjustment will improve visualization of blood flow if color extends outside the boundary of the vessel walls?

  • A. Increasing depth
  • B. Decreasing depth
  • C. Decreasing wall filter
  • D. Increasing wall filter

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When color "bleeds" outside vessel walls, it often results from motion artifacts or noise from slow tissue motion being displayed as flow. Increasing the wall filter eliminates low-frequency Doppler shifts caused by motion, improving color accuracy within vessel boundaries.
According to sonography instrumentation reference:
"Raising the wall filter eliminates low-velocity signals from vessel wall motion, reducing the appearance of color outside the vessel lumen." Therefore, the correct answer is C: Increasing wall filter.

NEW QUESTION # 123
Which gray-scale artifact occurs when a structure attenuates less than the adjacent tissues?

  • A. Range ambiguity
  • B. Enhancement
  • C. Refraction
  • D. Shadowing

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When sound passes through a structure that attenuates less than surrounding tissue (e.g., fluid-filled cyst), more sound reaches the tissues behind it, causing them to appear brighter. This artifact is called enhancement (or posterior acoustic enhancement).
According to sonography instrumentation reference:
"Posterior enhancement appears as increased echogenicity distal to a weakly attenuating structure due to greater beam intensity reaching deeper tissues." Therefore, the correct answer is A: Enhancement.

NEW QUESTION # 124
What is measured with a test object containing closely spaced, highly reflective targets along the direction of beam?

  • A. Axial resolution
  • B. Specificity
  • C. Lateral resolution
  • D. Sensitivity

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Axial resolution is the system's ability to distinguish two structures located along the direction of the ultrasound beam (parallel to the beam axis). Test objects or phantoms contain closely spaced pins or reflectors along this axis to evaluate axial resolution.
Principles and Instrumentation state:
"Axial resolution is determined by the spatial pulse length and is tested using targets positioned along the beam axis."
* Sensitivity (A) relates to detection of weak echoes.
* Specificity (B) refers to diagnostic accuracy, not phantom testing.
* Lateral resolution (C) is evaluated using side-by-side (perpendicular) targets.
Therefore, the correct answer is D: Axial resolution.
