20 Imaging modes
M Mode imaging
Motionmode(M Mode)isanextensionof2D.It
providesatraceofthe2Dimagedisplayedover
time.Asinglebeamofultrasoundistransmitted,
andreflectedsignalsaredisplayedasdotsof
varyingintensities,whichcreatelinesacrossthe
screen.
To display the M-line
1 PressModeandselectMMode.
2 UsethetouchpadtopositiontheM‐linewhere
desired.
3 Adjustcontrolsasdesired.
Manyoptimizationanddepthsettings
availablein2Dimagingarealsoavailablein
MModeimaging.See“2Dcontrols”on
page 19.
To display the M Mode trace
1 DisplaytheM‐line.
2 Adjustthedepthifnecessary.(See“Toadjust
depth”onpage 23.)
3 Doeitherofthefollowing:
•PressMModeontheleft.
•PressModeandselectMMode.
Thetimescaleabovethetracehassmallmarks
at200msintervals andlargemarksat
one‐secondintervals.
4 Do
anyofthefollowingasneeded:
•Selectthesweepspeed(Slow, Med,or
Fast).
•PressUpdate M ModeandUpdate 2Dto
togglebetweentheM‐lineandM‐Mode
trace.
•Ifusingaduplexlayout,pressModeand
thenselectMModetotogglebetweenthe
full‐screenM‐lineandtheduplex
layout.
Tosetaduplexlayout,see“Presetssetup”
onpage 16.
CPD and Color imaging
CPDisusedtovisualizethepresenceof
detectablebloodflow.Colorisusedtovisualize
thepresence,velocity,anddirectionofbloodflow
inawiderangeofflowstates.
To display the CPD or Color image
1 Dooneofthefollowing,dependingonyour
configuration:
•PressColor.ForCPD,pressCPDonthe
left.
Guide Turns guidelines on and off.
If using a variable angle needle guide,
press Guide and then press again to
select the angle: A, B, or C. The
touchpad moves the depth cursor.
See also Bracket and Needle Guide User
Guide or Bracket and Needle Guide for
L25 Series User Guide.
Guidelines are for needle guidance,
are an optional feature, and depend
on transducer type.
Dual Displays side-by-side 2D images.
Press Dual, and then press Update to
display the second screen and to
toggle between the screens. With
both images frozen, press Select to
toggle between the images.
To return to full-screen 2D imaging,
press Dual.
Brightness Adjusts the screen brightness. Press
the Brightness key and then turn the
Brightness knob. Settings range from
1 to 10. (You can also adjust the
brightness of only the key names and
icons. See “Presets setup” on
page 16.)
The screen brightness affects battery
life. To conserve battery life, adjust
brightness to a lower setting.
