ARDMS SPI Exam Syllabus Topics:
TopicDetails
Topic 1
  • Apply Doppler Concepts: This section of the exam measures skills of Vascular Sonographers and evaluates understanding and application of Doppler ultrasound principles. It includes knowledge of Doppler angle, flow dynamics, and color and spectral Doppler imaging. The section also covers eliminating aliasing, interpreting waveforms, applying continuous and pulsed wave Doppler, and optimizing Doppler gain and scale to accurately measure blood flow and velocity within vessels.
Topic 2
  • Manage Ultrasound Transducers: This section of the exam measures skills of Ultrasound Technicians and focuses on the management and proper use of different types of transducers. It evaluates knowledge of transducer components, frequency selection, and application of various 2D, 3D, 4D, and nonimaging transducer concepts. Candidates must show they can choose the appropriate transducer for specific examinations and make necessary frequency adjustments to ensure image quality.
Topic 3
  • Optimize Sonographic Images: This section of the exam measures skills of Diagnostic Medical Sonographers and assesses their ability to enhance image quality using advanced optimization techniques. It includes understanding axial, lateral, elevational, and temporal resolution, as well as manipulating gain, depth, magnification, and dynamic range. Examinees are expected to apply harmonic imaging, spatial compounding, and gray-scale techniques to produce clear, accurate diagnostic images.
Topic 4
  • Provide Clinical Safety and Quality Assurance: This section of the exam measures skills of Clinical Ultrasound Supervisors and focuses on maintaining safety and quality standards in ultrasound practice. It includes infection control protocols, transducer and machine integrity checks, and quality assurance testing using tissue-mimicking phantoms. The section also requires familiarity with statistical parameters like sensitivity and specificity to evaluate diagnostic performance and ensure consistent, reliable imaging outcomes.
Topic 5
  • Perform Ultrasound Examinations: This section of the exam measures skills of Sonographers and covers how to conduct ultrasound procedures while ensuring patient safety and diagnostic accuracy. It includes understanding of imaging protocols, ergonomics, patient care, and the interaction between sound and tissue. Candidates are expected to demonstrate abilities to manage patient encounters, apply 3D
  • 4D and contrast imaging concepts, identify and correct artifacts, and follow confidentiality and privacy standards throughout the scanning process.

ARDMS Sonography Principles and Instrumentation Sample Questions (Q158-Q163):NEW QUESTION # 158
What is the primary interaction that occurs when sound waves encounter a smooth, flat surface?
  • A. Attenuation
  • B. Interference
  • C. Reflection
  • D. Diffraction
Answer: C
Explanation:
When sound waves encounter a smooth, flat surface, the primary interaction is reflection. This means the sound waves bounce back towards the transducer, producing echoes that are used to create the ultrasound image. Reflection is most effective when the surface is smooth and perpendicular to the sound beam, allowing for the maximum return of sound waves to the transducer.

NEW QUESTION # 159
Which unfocused transducer will have the greatest divergence?
  • A. 6 mm aperture, 6 MHz
  • B. 4 mm aperture, 6 MHz
  • C. 4 mm aperture, 4 MHz
  • D. 6 mm aperture, 4 MHz
Answer: C
Explanation:
Transducer beam divergence is influenced by the aperture size and frequency. A smaller aperture and lower frequency result in greater beam divergence. Among the given options, the transducer with a 4 mm aperture and 4 MHz frequency will have the greatest divergence. This is because the smaller aperture size contributes to a wider beam spread, and the lower frequency also increases the divergence compared to higher frequencies.

NEW QUESTION # 160
Which pulsed-wave Doppler adjustment would be appropriate to correct the aliasing seen in this image?

  • A. Decrease the Doppler pulse repetition frequency.
  • B. Decrease the spectral Doppler gain.
  • C. Increase the spectral Doppler gain.
  • D. Increase the Doppler pulse repetition frequency.
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Aliasing occurs in pulsed-wave Doppler imaging when the Doppler shift frequency exceeds the Nyquist limit (which is half the pulse repetition frequency, PRF). This results in a wrap-around of the Doppler signal, which appears as a reversal of flow direction (aliasing artifact).
According to standard Principles and Instrumentation references in sonography:
"To eliminate aliasing, the Doppler PRF (scale) should be increased. Increasing the PRF raises the Nyquist limit and therefore allows for higher measurable velocities without aliasing." The correct adjustment to correct this aliasing artifact is C: Increase the Doppler pulse repetition frequency. This effectively increases the Nyquist limit and resolves the wrap-around aliasing appearance.
Options A and B (adjusting the spectral Doppler gain) would only change the appearance of the Doppler waveform (i.e., its amplitude and brightness) but would not affect aliasing. Option D (decreasing the PRF) would actually worsen the aliasing by lowering the Nyquist limit.
Therefore, the correct choice is to increase the Doppler PRF.

NEW QUESTION # 161
Which color Doppler control allows for reassignment of red and blue to represent flow direction?
  • A. Color threshold
  • B. Color priority
  • C. Color gain
  • D. Color invert
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In color Doppler imaging, the default color map assigns red and blue to represent flow direction relative to the transducer (usually red toward, blue away). The color invert control reverses this assignment.
According to sonography Principles and Instrumentation:
"The color invert control reverses the baseline of the color map, swapping red and blue assignments for flow direction." Color priority adjusts the overlay of color vs grayscale.
Color gain controls amplification of the Doppler signal.
Color threshold sets minimum amplitude to display color.
Therefore, the correct answer is D: Color invert.

NEW QUESTION # 162
What relates bandwidth to operating frequency?
  • A. Focal zone
  • B. Quality factor
  • C. Autocorrelation
  • D. Nyquist limit
Answer: B
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.
