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
  • 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
  • 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 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 (Q155-Q160):NEW QUESTION # 155
What reduces speckle and increases visualization of specular reflectors and attenuated structures?
  • A. Spatial compounding
  • B. Extended field of view
  • C. Pixel interpolation
  • D. Elastography
Answer: A
Explanation:
Spatial compounding involves acquiring multiple frames from different angles and averaging them. This technique reduces speckle noise, which is a granular interference pattern, and enhances the visualization of specular reflectors (smooth surfaces that reflect sound in a single direction) and attenuated structures (structures that reduce the intensity of the sound beam). By averaging frames from different angles, spatial compounding improves image quality and contrast resolution.

NEW QUESTION # 156
While imaging at a depth of 2 cm, which adjustment would improve the axial resolution?
  • A. Decrease gain
  • B. Turn off spatial compounding
  • C. Turn on harmonics
  • D. Increase frequency
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Axial resolution improves with shorter spatial pulse length, which is directly related to higher frequency. At shallow depths (such as 2 cm), higher frequency can be used effectively since attenuation is minimal.
Principles and Instrumentation state:
"Axial resolution improves with increasing frequency due to shorter wavelength and pulse length." Turning off spatial compounding (A) affects speckle reduction.
Harmonics (B) help with resolution but primarily lateral contrast.
Gain (C) affects brightness, not resolution directly.
Therefore, the correct answer is D: Increase frequency.

NEW QUESTION # 157
Which color Doppler setting adjustment would likely demonstrate color flow in the normal vein seen in this image?

  • A. Increasing scale
  • B. Increasing persistence
  • C. Decreasing scale
  • D. Decreasing persistence
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Veins generally exhibit low-velocity flow. The color scale (or velocity range) must be low enough to detect these slow flows. Decreasing the scale lowers the Nyquist limit, allowing the machine to display lower velocities that may otherwise be undetectable.
Principles and Instrumentation state:
"Reducing the scale increases sensitivity to low-velocity flows such as venous flow, while high scales may suppress these signals." Therefore, the correct answer is A: Decreasing scale.

NEW QUESTION # 158
What adjustment is needed to visualize the borders of the anatomical structures in the image below?

  • A. Increase dynamic range
  • B. Increase sector width
  • C. Decrease depth
  • D. Lower focal zone
Answer: A
Explanation:
Dynamic range in ultrasound imaging refers to the range of signal amplitudes that the system can display.
Increasing the dynamic range allows the ultrasound system to display a broader range of echo amplitudes, which enhances the contrast resolution and helps to visualize subtle differences in tissue texture and borders of anatomical structures. When the dynamic range is increased, more shades of gray are used, making the image appear softer and less contrasty, which is beneficial for delineating the borders of anatomical structures more clearly.

NEW QUESTION # 159
Which color Doppler artifact is visualized in this image?

  • A. Aliasing
  • B. Bleed
  • C. Twinkle
  • D. Ghosting
Answer: A
Explanation:
The color Doppler image shows an artifact where high-velocity blood flow exceeds the Nyquist limit, resulting in color wrap-around or aliasing. This artifact is visualized as a mosaic pattern of colors that abruptly change, indicating that the velocity exceeds the color Doppler scale's maximum. Aliasing occurs when the sampling rate (pulse repetition frequency) is insufficient to accurately capture the high velocities, causing the display to cycle back to lower velocities.
