Ch 11: Display Modes Flashcards
The three basic modes of display or formats are…
1) amplitude mode
2) brightness mode
3) motion mode
This display mode appears as a series of upward spikes.
A-mode (amplitude)
In which display mode does the sound pulse emited by the transucer show as a dot moving at a constant speed across the system’s display?
A-mode (amplitude)
In which display mode does a reflection return to the transducer, then get processed into a moving dot deflected upward on the screen?
A-mode (amplitude)
In A-mode, the ___ of the upward deflection is ___ to the amplitude of the returning echo.
height, proportional
In A-mode, the x-axis display represents ___.
depth
In A-mode, the y-axis display represents ___.
amplitude.
A-mode is used almost exclusively in ___.
ophthalmology
This display mode appears as a line of dots of varying brightness.
B-mode
In which display mode does an invisible dot move at a constant speed across the system’s display?
B-mode
In which display mode is the reflection processed and an invisible dot turned on?
B-mode
In B-mode the ___ of the dot indicates the ___ of the reflection.
brightness, strength
In B-mode, the x-axis represents ___.
depth
In B-mode, the y-axis represents ___.
Trick question! There’s no y-axis in B-mode.
In B-mode, the z-axis represents ___.
amplitude
