ARDMS Sonography Principles and Instrumentation Sample Questions (Q48-Q53):

NEW QUESTION # 48
Which artifact causes a reflector to be improperly positioned on the display?

  • A. Range ambiguity
  • B. Enhancement
  • C. Acoustic shadowing
  • D. Speckle

Answer: A

Explanation:
Acoustic Shadowing: This artifact occurs when a structure absorbs or reflects most of the ultrasound waves, causing a shadow behind the structure. It does not cause improper positioning of a reflector on the display.
Speckle: This is a form of noise in ultrasound imaging that appears as granular texture. It can affect image quality but does not lead to improper positioning of reflectors.
Enhancement: This artifact occurs when the area behind a weakly attenuating structure appears brighter. It affects the brightness of the image but does not affect the position of reflectors.
Range Ambiguity: This occurs when an echo is received after the next pulse has been sent out, causing the reflector to be placed at an incorrect depth on the display. This is because the system assumes the echo came from the most recent pulse.

NEW QUESTION # 49
Which adjustment would reduce the noise in the Doppler waveform in this image?

  • A. Decreasing Doppler gain
  • B. Decreasing velocity scale
  • C. Increasing the gate size
  • D. Increasing sweep speed

Answer: A

Explanation:
Noise in the Doppler waveform can often be attributed to excessive gain settings. Decreasing the Doppler gain reduces the amplification of both the signal and the noise, thus providing a clearer and more accurate Doppler waveform. Excessive gain can cause speckling and clutter, which obscure the true Doppler signals. By reducing the gain, the noise level is minimized, resulting in a cleaner Doppler signal representation.

NEW QUESTION # 50
A Doppler shift is 10,000 Hz at an angle of flow of 60 degrees. What is the Doppler shift at 0 degrees?

  • A. 2,500 Hz
  • B. 20,000 Hz
  • C. 5,000 Hz
  • D. 10,000 Hz

Answer: B

Explanation:
depends on the angle between the ultrasound beam and the direction of blood flow. The Doppler equation includes a cosine function of the angle of insonation (θ). At 60 degrees, the cosine is 0.5, and at 0 degrees (parallel to the flow), the cosine is 1. Thus, if the Doppler shift is 10,000 Hz at 60 degrees, it would double to 20,000 Hz at 0 degrees because the cosine of 0 degrees is 1 (cos(0°) = 1) and the cosine of 60 degrees is 0.5 (cos(60°) = 0.5). The formula is: Doppler shift at 0 degrees = Doppler shift at 60 degrees / cos(60 degrees) = 10,000 Hz / 0.5 = 20,000 Hz.

NEW QUESTION # 51
What relates bandwidth to operating frequency?

  • A. Focal zone
  • B. Autocorrelation
  • C. Quality factor
  • D. Nyquist limit

Answer: C

Explanation:
The quality factor (Q-factor) is a dimensionless parameter that describes the efficiency of the transducer in terms of bandwidth and operating frequency. It is defined as the ratio of the operating frequency to the bandwidth. A higher Q-factor indicates a narrower bandwidth relative to the operating frequency, resulting in more precise frequency characteristics but potentially reduced axial resolution. Conversely, a lower Q-factor indicates a broader bandwidth, which improves axial resolution but may result in less precise frequency characteristics.

NEW QUESTION # 52
Which resolution is improved by focusing?

  • A. Axial
  • B. Contrast
  • C. Temporal
  • D. Lateral

Answer: D

Explanation:
Focusing improves lateral resolution in ultrasound imaging. Lateral resolution refers to the system's ability to distinguish between two points that are side by side (perpendicular to the sound beam's path). By focusing the ultrasound beam, the width of the beam is narrowed at the focal point, enhancing the system's ability to resolve structures that are close together in the lateral plane. This results in clearer, more detailed images of the anatomical structures.
