Once our professionals find the relevent knowledge on the SPI exam questions, then the whole research groups will pick out the knowledge points according to the test syllabus. Also, they will also compile some questions about the SPI practice materials in terms of their experience. Now, we have successfully summarized all knowledge points in line with the SPI outline. And meanwhile, we keep a close eye on the changes of the exam to make sure what you buy are the latest and valid.
ARDMS SPI Exam Syllabus Topics:
TopicDetails
Topic 1
  • 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.
Topic 2
  • 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 3
  • 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 4
  • 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 5
  • 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.

ARDMS Sonography Principles and Instrumentation Sample Questions (Q86-Q91):NEW QUESTION # 86
Which artifact is caused by defects in the crystals of the transducer?
  • A. Mirror image
  • B. Ringdown
  • C. Side lobe
  • D. Dropout
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Defects in transducer crystals result in missing or weakened signals along the beam path produced by those elements, creating dropout. In array transducers, dropout typically appears as vertical or horizontal dark zones depending on which elements are affected.
According to sonography instrumentation reference:
"Crystal failure results in areas of signal dropout directly beneath the defective elements due to loss of transmitted or received signals." Therefore, the correct answer is D: Dropout.

NEW QUESTION # 87
Which target group is used to evaluate transverse distance measurement accuracy in this tissue-mimicking phantom image?
A ultrasound image of a baby Description automatically generated with medium confidence

  • A. A
  • B. B
  • C. D
  • D. C
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In a tissue-mimicking phantom, the group of targets aligned side-by-side (horizontally) is used to evaluate transverse (lateral) distance measurement accuracy. In the image, target group C (in red) represents the lateral spacing targets.
Principles and Instrumentation state:
"Transverse distance accuracy is evaluated using laterally spaced targets in the phantom to verify correct lateral measurement calibration."
* Group A (top) is typically for near field assessment.
* Group B may be for axial resolution or cyst evaluation.
* Group D (deep) may assess depth calibration or sensitivity.
Therefore, the correct answer is C: C.

NEW QUESTION # 88
What happens to the Doppler shift when the angle is changed from 30 to 60 degrees?
  • A. Loss of Doppler signal
  • B. Decreases
  • C. Increases
  • D. No significant change
Answer: B
Explanation:
The Doppler shift is directly related to the cosine of the angle between the ultrasound beam and the direction of blood flow. As the angle increases from 30 degrees to 60 degrees, the cosine of the angle decreases (cosine of 30 degrees is approximately 0.87, while cosine of 60 degrees is 0.5). Since the Doppler shift is proportional to the cosine of the angle, increasing the angle results in a decreased Doppler shift. This means the measured blood flow velocities will appear lower at a 60-degree angle compared to a 30-degree angle.

NEW QUESTION # 89
Which unfocused transducer will have the greatest divergence?
  • A. 6 mm aperture, 6 MHz
  • B. 4 mm aperture, 4 MHz
  • C. 6 mm aperture, 4 MHz
  • D. 4 mm aperture, 6 MHz
Answer: B
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 # 90
What is the effect of increasing the sample volume on the spectral Doppler signal tracing?
  • A. Increased noise
  • B. Increased velocity sensitivity
  • C. Decreased sweep speed
  • D. Decreased aliasing
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A larger sample volume collects Doppler signals from a wider region, which can include multiple velocities and noise. This leads to a broader spectrum (spectral broadening) and may introduce additional noise into the signal.
According to sonography instrumentation reference:
"Increasing the sample volume size increases the likelihood of including multiple velocity components and noise, resulting in spectral broadening and reduced spectral clarity." Therefore, the correct answer is B: Increased noise.
