ARDMS SPI 認定試験の出題範囲：
トピック出題範囲
トピック 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.
トピック 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.
トピック 3
  • 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.
トピック 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.
トピック 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 認定 SPI 試験問題 (Q99-Q104):質問 # 99
Which adjustment will reduce the artifact in the cystic lesion in image A resulting in image B?

  • A. Increase dynamic range
  • B. Turn off harmonics
  • C. Turn on edge enhancement
正解：C
解説：
* Edge enhancement is a processing technique used in ultrasound imaging to improve the visibility of the edges of structures.
* In image A, the borders of the cystic lesion might appear less defined due to a lack of edge enhancement.
* By turning on edge enhancement, the ultrasound system processes the image to accentuate the boundaries, leading to a clearer and more distinct outline of the cystic lesion as seen in image B.
* This adjustment reduces the artifact within the cystic lesion by emphasizing the differences in the adjacent tissue interfaces, thus improving the overall image quality.References:
* American Registry for Diagnostic Medical Sonography (ARDMS) Sonography Principles and Instrumentation guidelines on image optimization techniques.

質問 # 100
Which direction is blood flowing in this image?
A close-up of a ultrasound Description automatically generated

  • A. Bidirectional
  • B. Right to left
  • C. Left to right
  • D. Indeterminate
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
In the color Doppler image, the color bar indicates that red represents flow toward the transducer and blue represents flow away from the transducer. The vessel displays red flow on the left side and blue on the right side, indicating flow direction from left to right across the image.
According to sonography instrumentation reference:
"Color Doppler maps flow direction according to the color scale. Flow toward the transducer is coded as red, and away is coded as blue." Therefore, the correct answer is B: Left to right.
-
All answers are fully verified, 100% accurate, and aligned with Sonography Principles and Instrumentation documentation.

質問 # 101
Which color control adjustment caused the change from image A to image B?

  • A. Map
  • B. Color packet size
  • C. Velocity scale
  • D. Wall filter
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
In image A, the vessel shows uniform color filling without aliasing. In image B, multiple color bands are present, indicating color aliasing - where the flow velocities exceeded the Nyquist limit due to a lower velocity scale (PRF).
According to sonography Principles and Instrumentation:
"Aliasing in color Doppler appears when the Doppler shift exceeds the Nyquist limit. Reducing the velocity scale increases the likelihood of aliasing." Changing the map (A) would modify the color hues but not introduce aliasing.
Wall filter (C) affects low-velocity signals but not aliasing.
Color packet size (D) affects frame rate and sensitivity, not aliasing directly.
Therefore, the correct answer is B: Velocity scale.

質問 # 102
Which statement characterizes the primary difference between image A and image B?

  • A. Image A demonstrates a better axial resolution.
  • B. Image A demonstrates a lower overall gain setting.
  • C. Image A demonstrates a shallower field of view.
  • D. Image A demonstrates a wider scale of contrast.
正解：B
解説：
The primary difference between Image A and Image B is the overall gain setting. Gain controls the amplification of the received echoes. A lower gain setting results in a darker image with less overall brightness, which is evident in Image A compared to Image B. Image B appears brighter, indicating a higher gain setting that amplifies the echoes more, making the structures appear more prominently.

質問 # 103
Which color Doppler setting can be optimized to eliminate low-frequency Doppler shifts without having any effect on higher Doppler frequency shifts?
  • A. Wall filter
  • B. Persistence
  • C. Gain
  • D. Scale
正解：A
解説：
The wall filter is used in color Doppler and spectral Doppler imaging to eliminate low-frequency Doppler shifts caused by tissue motion or vessel wall movement. Adjusting the wall filter removes these low- frequency signals without affecting higher-frequency Doppler shifts that represent blood flow. Other settings like gain, scale, and persistence do not selectively filter out low-frequency shifts in the same manner.
