Modes of Display Quiz

What are the three basic modes of display or formats?

• Amplitude Mode, Brightness Mode, Motion Mode

• Frequency Mode, Color Mode, Speed Mode

• Volume Mode, Contrast Mode, Time Mode

• Height Mode, Width Mode, Depth Mode

What does A-mode appear as on a display?

• A series of downward spikes

• A series of upward spikes

• A flat line

• A circular pattern

What happens when a sound pulse is emitted by the transducer in A-mode?

• A dot moves at a constant speed across the system’s display

• The screen turns off

• The display shows a circular pattern

• The transducer stops working

What occurs when a reflection returns to the transducer in A-mode?

• The dot disappears

• The moving dot is deflected downward on the screen

• The moving dot is deflected upward on the screen

• The screen changes color

For what purpose is A-mode used in ophthalmology?

• To detect color blindness

• To measure eye pressure

• To detect findings in the optic nerve

• To test visual acuity

What does A-mode in ultrasonography represent?

• Two-dimensional imaging

• Three-dimensional imaging

• One-dimensional imaging

• Four-dimensional imaging

In A-mode, what does the x-axis represent?

• Amplitude

• Frequency

• Depth

• Time

In A-mode, what does the y-axis represent?

• Depth

• Amplitude

• Frequency

• Time

What is B-Mode, or Brightness Modulation, used for in ultrasound imaging?

• Displaying a 3D map of B-Mode data

• Displaying a 2D map of B-Mode data

• Displaying a 1D map of B-Mode data

• Displaying a 4D map of B-Mode data

How does B-Mode differ from A-Mode in ultrasound imaging?

• B-Mode uses vertical spikes for brightness

• B-Mode is based on color intensity

• B-Mode is based on brightness without vertical spikes

• B-Mode uses sound frequency for brightness
