Ch. 11 Display Modes Flashcards
What are the three basic modes of display or formats of viewing ultrasound:
- Amplitude mode
- Brightness mode
- Motion mode
_________ mode aka ___________________ mode appears as a series of upward spikes
A-mode aka Amplitude mode appears as a series of upward spikes
On A-mode or Amplitude mode the x-axis represents ________________ and the y-axis represents ______________________
On A-mode or Amplitude mode the x-axis represents depth and the y-axis represents amplitude
______ mode aka as ____________________ mode appears as a line of dots of varying brightness, the brightness of the dot indicates the strength of the reflection
B-mode aka as Brightness mode appears as a line of dots of varying brightness, the brightness of the dot indicates the strength of the reflection
The x-axis of B-mode represents ____________ and the y-axis represents _____________ and the z-axis represents ___________________
The x-axis of B-mode represents depth and the y-axis represents nothing and the z-axis represents amplitude
_______ mode or ________________ mode appears as a group of horizontal wavy lines. Various squiggly lines that represent the changing of depth of the reflecting surfaces are produced on the screen.
M-mode or Motion mode appears as a group of horizontal wavy lines. Various squiggly lines that represent the changing of depth of the reflecting surfaces are produced on the screen.
The x-axis on M-mode display represents ______________, and the y-axis represents ___________
The x-axis on M-mode display represents time and the y-axis represents depth
What is the only display mode that provides information regarding reflector motion with respect to time?
M-mode
With A-mode, what is displayed on the x-axis?
Depth of the reflector
With M-mode, what is displayed on the y-axis?
Depth of the reflector
Which mode provides the foundation for real-time, gray scale anatomic imaging?
B-mode, or brightness mode
With A-mode, what is displayed on the y-axis?
Amplitude of the reflected signal
In M-mode, what is displayed on the x-axis?
time
With B-mode, which axis is related to the strength of the reflection?
The z-axis is related to reflection strength.
Which imaging modality places time-of-flight information on the x-axis and echo amplitude on the y-axis?
A. M-mode
B. L-mode
C. J-mode
D. A-mode
D. A-mode, or Amplitude mode, displays reflector depth on the x-axis. Reflector depth is determined by a pulse’s time of flight. The strength of the reflection is displayed on the y-axis.
Which imaging mode accurately displays reflector depth?
A. I-mode
B. L-mode
C. C-mode
D. A-mode
D. A-mode, or amplitude mode, displays the reflector depth accurately. A-mode is used in ophthalmology, which requires precise measures of depth or thickness
Which imaging technique usually displays a single jagged line of varying heights?
A. A-mode
B. B-mode
C. C-mode
D. I-mode
A. A-mode displays reflected echoes as spikes of varying height. Echo amplitude appears on the y-axis, and reflector depth on the x-axis. The spike’s location on the x-axis is based on the pulse’s time-of-flight. The height of the peak is determined by the reflection’s strength. Stronger reflections create higher spikes.
With B-mode, on which axis is the strength of the reflection input?
A. x-axis
B. y-axis
C. z-axis
C. With B-mode, reflection strength is input into the z-axis
Which imaging modality places dots of dissimilar gray scale on the display?
A. A-mode
B. I-mode
C. B-mode
D. M-mode
C. Brightness mode, or B-mode, displays reflected echoes as spots of varying brightness. The depth of the dot is based on the time-of-flight. Stronger reflections create brighter dots. Weaker reflections create darker dots.
The mode that produces lines related to the changing position of reflectors in the body with respect to time is called _______.
A. A-mode
B. M-mode
C. B-mode
D. a la mode
B. The imaging mode that displays the position of reflectors throughout time is M-mode, or motion mode. M-mode is the only display that provides reflector position throughout time.
To which of the following do the x-axis of a B-mode, the y-axis of an M-mode and the x-axis of an A-mode all relate?
A. depth of view
B. go time
C. echo amplitude
D. time of flight
D. All three of these measurements report the reflector depth. Reflector depth is determined by a pulse’s time of flight.
