ARDMS Sonography Principles and Instrumentation Sample Questions (Q137-Q142):

NEW QUESTION # 137
Which artifact may be caused by incorrect color Dopplergain setting?

  • A. Bleed/Blossoming
  • B. Twinkle
  • C. Aliasing
  • D. Clutter/Haze

Answer: A

Explanation:
Incorrect color Doppler gain settings can cause the artifact known as bleed or blossoming. When the color Doppler gain is set too high, it can cause the color signal to "bleed" outside the actual boundaries of the blood vessel, leading to an overestimation of the area of flow. This artifact makes it appear as though the blood flow extends beyond the true vessel walls, which can obscure the accurate interpretation of the Doppler image.

NEW QUESTION # 138
The calipers in this image measure which performance characteristic of a system?

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

Answer: C

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 # 139
Which target group in this image of a tissue-mimicking phantom is used for gray-scale evaluation?

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

Answer: A

Explanation:
* Gray-scale evaluation in a tissue-mimicking phantom involves assessing the uniformity and accuracy of the gray-scale representation of the tissues.
* Option C typically contains structures designed to test the machine's ability to accurately depict varying levels of echogenicity, which is essential for proper gray-scale evaluation.
* This area will have a range of echo intensities that help in determining the contrast resolution and the ability of the system to distinguish between different tissue types based on their gray-scale values.

* ARDMS Sonography Principles and Instrumentation guidelines on tissue-mimicking phantoms and image quality evaluation.


NEW QUESTION # 140
Which structure can be evaluated using M-mode?

  • A. Heart
  • B. Kidneys
  • C. Liver
  • D. Pancreas

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
M-mode (motion mode) ultrasound records the movement of structures along a single scan line over time. It is particularly valuable in cardiac imaging where precise motion of heart valves and walls is evaluated.
Principles and Instrumentation reference:
"M-mode is primarily used in echocardiography to evaluate the motion of cardiac structures with high temporal resolution."
* Liver, kidneys, and pancreas are evaluated using B-mode, not M-mode.
Therefore, the correct answer is A: Heart.


NEW QUESTION # 141
What is the primary factor that affects axial resolution?

  • A. Focal zone
  • B. Speed of sound
  • C. Spatial pulse length
  • D. Aperture

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Axial resolution refers to the ability to distinguish two structures that are located along the path of the ultrasound beam. It is directly related to the spatial pulse length (SPL), which is the product of the number of cycles per pulse and the wavelength. A shorter SPL leads to better axial resolution.
According to sonography instrumentation reference:
"Axial resolution improves as spatial pulse length decreases because shorter pulses can better differentiate structures lying close together along the beam axis." Therefore, the correct answer is B: Spatial pulse length.
