Sample Ultrasound Physics Quiz - Quiz

This is a sample quiz to assess a students ability to select equipment parameters to optimize temporal resolution.


Questions and Answers
  • 1. 

    Which resolution is determined by frame rate?

    • A.

      Temporal resolution

    • B.

      Axial resolution

    • C.

      Spatial resolution

    • D.

      Lateral resolution

    Correct Answer
    A. Temporal resolution
    Explanation
    temporal resolution is directly related to frame rate

    Rate this question:

  • 2. 

    Which system setting would increase frame rate?

    • A.

      Decreased depth

    • B.

      Multiple focus

    • C.

      Wide sector

    • D.

      High line density

    Correct Answer
    A. Decreased depth
    Explanation
    multiple focus, wide sector and high line density would all decrease frame rate

    Rate this question:

  • 3. 

    Which system setting could increase the listening time and decrease temporal resolution?

    • A.

      Depth

    • B.

      Power

    • C.

      Amplification

    • D.

      Compression

    Correct Answer
    A. Depth
    Explanation
    power, amplification and compression have no effect on temporal resolution

    Rate this question:

  • 4. 

    Which resolution would be the most important when evaluating the heart with respect to motion? 

    • A.

      Temporal

    • B.

      Axial

    • C.

      Spatial

    • D.

      Lateral

    Correct Answer
    A. Temporal
    Explanation
    The most important resolution when evaluating the heart with respect to motion would be temporal resolution. Temporal resolution refers to the ability to capture and distinguish rapid changes over time. In the context of evaluating the heart, it is crucial to have high temporal resolution to accurately assess the motion and function of the heart. This allows for the detection of abnormalities such as arrhythmias or abnormal contractions that may not be visible with lower temporal resolution.

    Rate this question:

  • 5. 

    Which resolution is made worse in Image B by increasing the number of focal zones? 

    • A.

      Temporal

    • B.

      Lateral

    • C.

      Spatial

    • D.

      Axial

    Correct Answer
    A. Temporal
    Explanation
    temporal resolution is worse with multiple focal zones but lateral resolution is improved
