ARDMS Sonography Principles and Instrumentation SPI Prüfungsfragen mit Lösungen (Q81-Q86):

81. Frage
Which settings would produce the best temporal resolution?

A. Fewer focal zones and shallower depth
B. More focal zones and shallower depth
C. More focal zones and deeper depth
D. Fewer focal zones and deeper depth

Antwort: A

Begründung:
Comprehensive and Detailed Explanation From Exact Extract:
Temporal resolution refers to the system's ability to accurately track moving structures over time (i.e., frame rate). Temporal resolution improves when:
* The number of focal zones is reduced (fewer focal zones = faster frame rate).
* The imaging depth is reduced (shallower depth = faster frame rate).
According to sonography instrumentation references:
"Fewer focal zones and shallow imaging depth optimize temporal resolution by decreasing the time required for each frame, resulting in a higher frame rate." Therefore, the correct answer is C: Fewer focal zones and shallower depth.

82. Frage
Which factor causes posterior acoustic enhancement?

A. Strongly attenuating structure
B. Low-frequency transducer
C. Weakly attenuating structure
D. High-frequency transducer

Antwort: C

Begründung:
High-Frequency Transducer: These provide better resolution but do not directly cause posterior enhancement.
Low-Frequency Transducer: These provide better penetration but are not the cause of posterior enhancement.
Strongly Attenuating Structure: This would cause acoustic shadowing rather than enhancement.
Weakly Attenuating Structure: Structures that attenuate the ultrasound beam less than the surrounding tissues allow more sound waves to pass through, resulting in increased brightness or "enhancement" behind the structure.

83. Frage
What is the most effective way to reduce aliasing on color Doppler?

A. Increase wall filter
B. Increase pulse repetition frequency (PRF)
C. Decrease wall filter
D. Decrease pulse repetition frequency (PRF)

Antwort: B

Begründung:
Aliasing in color Doppler occurs when the velocity of blood flow exceeds the Nyquist limit, which is half the PRF. To reduce aliasing, the PRF must be increased. This raises the Nyquist limit, allowing higher velocities to be measured without wrapping around the baseline. Increasing PRF reduces the occurrence of aliasing artifacts by expanding the range of detectable velocities before aliasing occurs.

84. Frage
What is the function of M-mode?

A. Visualize internal organs
B. Measure movement
C. Create 3D images
D. Monitor blood flow

Antwort: B

Begründung:
* M-mode (Motion mode) is used in ultrasound to measure and display the movement of structures over time.
* This mode is particularly useful in cardiac imaging to assess the motion of heart walls and valves.
* M-mode provides a one-dimensional view of the motion of tissues and is often used in conjunction with
2D imaging for a comprehensive assessment.
* It is essential in evaluating the dynamic function of organs, especially in cardiology, where precise measurements of cardiac structures' movement are crucial.References:

85. Frage
What improves the temporal resolution of color flow imaging?

A. Increasing number of color lines per frame
B. Decreasing pulse repetition frequency
C. Decreasing width of the color field of view
D. Increasing ensemble length (packet size)

Antwort: C

Begründung:
Temporal resolution refers to the ability of the ultrasound system to distinguish events occurring closely in time. In color flow imaging, temporal resolution is affected by the frame rate, which can be increased by decreasing the width of the color field of view. This is because a narrower color field requires fewer scan lines to be processed, allowing for more frames to be captured per second.
