ARDMS SPI Exam Syllabus Topics:
TopicDetails
Topic 1
  • 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 2
  • 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 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
  • 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 5
  • 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.

ARDMS Sonography Principles and Instrumentation Sample Questions (Q188-Q193):NEW QUESTION # 188
Which change should be made to lower the mechanical index (MI)?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Mechanical Index (MI) is proportional to the peak negative pressure and inversely proportional to the square root of frequency. Lowering output power directly decreases the peak pressure, thus reducing MI.
Principles and Instrumentation state:
"Mechanical index decreases with lower output power, reducing the risk of mechanical bioeffects such as cavitation." Lowering frequency (A) increases MI.
Tissue harmonics (B) improves image quality but does not reduce MI directly.
Increasing gain (D) affects displayed brightness, not acoustic power.
Therefore, the correct answer is C: Decreasing output power.

NEW QUESTION # 189
What is the effect of an increased aperture in a linear array transducer?
Answer: C
Explanation:
The aperture of a transducer is the active area that emits and receives the ultrasound waves. In a linear array transducer, increasing the aperture (using more elements for transmission and reception) results in a deeper focus because the beam is more tightly focused over a longer distance. This improves lateral resolution at greater depths, as the ultrasound beam maintains a narrower width for a longer distance. It allows for better imaging of deeper structures without sacrificing resolution.

NEW QUESTION # 190
What is an advantage of power Doppler over color Doppler?
Answer: B
Explanation:
Power Doppler, unlike color Doppler, is less angle dependent because it detects the strength of the Doppler signal rather than the velocity of the blood flow. This means it is more sensitive to detecting low-velocity flow and flow in smaller vessels, regardless of the angle between the ultrasound beam and the flow direction. Color Doppler provides information on flow direction and velocity but is highly dependent on the angle of insonation, making it less reliable when the angle is suboptimal.

NEW QUESTION # 191
Which technique averages individual frames together to improve the image?
Answer: D
Explanation:
Persistence is a technique used in ultrasound imaging that averages individual frames together to improve the overall image quality. This process helps to reduce noise and improve the signal-to-noise ratio, leading to clearer and more stable images. By averaging multiple frames, transient artifacts are minimized, and the continuity of structures is better visualized. Persistence is particularly useful in imaging static or slow-moving structures.

NEW QUESTION # 192
Which feature is a characteristic of write magnification?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Write magnification acquires new data over the smaller field of view with a higher number of scan lines, improving spatial resolution.
Principles and Instrumentation state:
"Write magnification rescans the selected region with new data acquisition, increasing the number of pixels and improving resolution."
* Post-processing (A) applies to read magnification.
* Larger pixel size (C) would decrease resolution.
* Write magnification improves, not decreases (D), spatial resolution.
Therefore, the correct answer is B: New data acquisition.
