ARDMS SPI 認定試験の出題範囲：
トピック出題範囲
トピック 1
  • 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.
トピック 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.
トピック 3
  • 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 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
  • 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 認定 SPI 試験問題 (Q125-Q130):質問 # 125
At which angle to blood flow would the maximum Doppler shift occur?
  • A. 90 degrees
  • B. 0 degrees
  • C. 30 degrees
  • D. 60 degrees
正解：B
解説：
The Doppler shift is highest when the angle between the ultrasound beam and the direction of blood flow is 0 degrees. This is because the cosine of 0 degrees is 1, maximizing the Doppler frequency shift. As the angle increases towards 90 degrees, the cosine value decreases, reducing the Doppler shift.

質問 # 126
Which change should be made to lower the mechanical index (MI)?
  • A. Increasing gain
  • B. Activating tissue harmonics
  • C. Decreasing output power
  • D. Lowering transducer frequency
正解：C
解説：
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.

質問 # 127
Which artifact displays reflectors more shallow than their actual position?
  • A. Ring-down
  • B. Mirror image
  • C. Range ambiguity
  • D. Section thickness
正解：C
解説：
Range ambiguity artifact occurs when echoes from one pulse are received after the next pulse has been emitted, leading to the incorrect placement of echoes at shallower depths than their true location. This artifact typically happens when the PRF is set too high, causing the ultrasound system to interpret delayed echoes as coming from the current pulse rather than the previous one. This results in reflectors appearing closer to the transducer than they actually are.

質問 # 128
What is the relationship between overall gain and image brightness?
  • A. There is no relationship between overall gain and image brightness
  • B. The higher the overall gain, the brighter the image
  • C. The lower the overall gain, the brighter the image
  • D. The higher the overall gain, the darker the image
正解：B
解説：
Overall gain in ultrasound refers to the amplification of all the received echo signals. Increasing the overall gain amplifies the signals, making the entire image brighter. Conversely, decreasing the overall gain reduces the signal amplification, resulting in a darker image. Overall gain adjustment affects the entire image uniformly, unlike time gain compensation (TGC), which adjusts the gain at different depths independently.

質問 # 129
How is intensity of an ultrasound beam measured?
  • A. Autocorrelation
  • B. Hydrophone
  • C. Reynold's number
  • D. Doppler equation
正解：B
解説：
The intensity of an ultrasound beam is measured using a hydrophone. A hydrophone is a specialized device that detects and measures the acoustic pressure of the ultrasound waves in water or tissue-mimicking materials. It is highly sensitive and can measure the variations in pressure, which are used to calculate the intensity and other acoustic parameters of the ultrasound beam.
