Mode applied to intensity data calculates and color-codes 
tissue and Angio intensity along a path drawn by the 
operator vs. time.
WARNINGMisdiagnosis based on image artifacts
Misdiagnosis in ultrasound contrast images may be caused by 
several artifacts, most importantly:
Motion artifacts: gives rise to signals independently of contrast 
presence. This may be caused by patient movement; including 
respiration, or by probe movement influenced by the operator.
Regional drop outs: caused by unintentional destruction of the 
contrast agent, too low concentration of contrast agent, poor 
acoustic penetration due to rib/lung shadows or system failing to 
detect the contrast agent due to erroneous settings induced by 
the operator.
Tissue harmonics: gives contrast-like signals independently of 
the presence of contrast agent.
The field of myocardial perfusion using contrast agents is still a 
research field. The myocardial applications Real Time MC and 
MC Contrast are research tools for the development of this field. 
Default machine settings are set to minimize the amount these 
artifacts, but the operator has to take these artifacts into account 
while analyzing the data and confirm the results using other 
techniques.

Data acquisition
Left Ventricular Contrast Imaging
The Left Ventricular (LV) Contrast application has an optimized 
system preset for optimal resolution of endocardial borders and 
for optimal assessment of wall motion and wall thickening.
The LV Contrast application may help to identify LV thrombus 
and evaluate wall motion.

LV Contrast controls
LV Contrast assignables controls
Width
Controls the size and angular width of the image sector. A 
smaller angle generally produces a scan with a higher frame 
rate.
Frequency
Enables the adjustment of the probes operating frequency. A 
higher frequency gives better resolution.
Focus
Changes the location of the focal point. A triangular marker on 
the depth scale along the image sector indicates the position of 
the focal point.
Frame rate
Lower frame rate 
gives better resolu-
tion.Controls the line density.
Up/Down
Enables the 2D image to be flipped 180 degrees.
Left/Right
Enables the display of a mirrored image. When applied, the 
reference marker V moves to the other side of the image.
Angio
Turns Coded harmonic angio (color) on/off.
B Color maps
Displays a 2D maps menu to optimized the grey scale 
presentation. The menu enables an option from a list of non-
linear grey-curves or different 2D-colorized curves to be 
selected.
LV Contrast Soft menu controls
Power
Controls the amount of acoustic power applied to the 
transmitted pulse.

Too high Power lev-
el will destroy the 
contrast agent.Compress
Controls the degree of image contrast.
Reject
Controls the Echo rejection level. When increased, low level 
echoes are rejected and appear darker in the 2D image.
Dynamic Range
Controls the image contrast. A high dynamic range setting 
gives a softer image.
Tilt
Enables the axis of the 2D image to be tilted to the left or to the 
right. By default the axis of the 2D image is vertical.
Contour
Controls the image processing related to the extent of edge 
enhancement applied.
The Diff control de-
creases the frame 
rate and the number 
of focal zones when 
turned on.Diff on/off
Affects the level of reverberation in the image. The 
reverberation in the image is reduced when Diff control is 
turned on.
DDP (Data Dependant Processing)
Performs temporal processing, which reduces random noise 
without affecting the motion of significant tissue structures.

Running LV Contrast
The LV Contrast application works only with the M3S, 3S, 5S 
and 6T probes.
To select LV Con-
trast application 
without changing 
the current probe, 
press 
APPL. on the 
control panel.
1. Press PROBE on the control panel.
A list of the connected probes is displayed.
2. Trackball to the desired probe supporting the LV Contrast 
application.
The Application menu for the selected probe is listed.
3. Trackball to LV Contrast application.
4. Press 
SELECT to launch the application.
5. Perform the acquisition.
Optimizing LV Contrast
The default setting for the LV contrast application is optimal 
setting for the application (MI=0.5; Freq.=1.7/3.4; Focus=9 cm). 
However, depending on the acoustic window of the patient or 
the specific contrast agent being used, there may be need for 
further adjustment.
If image quality is not acceptable before contrast injection, the 
power level should be increased. When contrast is observed in 
the left ventricle, the power should be reduced to a level giving 
homogenous opacification with no destruction (shown as a 
swirling pattern) of the contrast agent in the LV cavity. If a 
swirling pattern is observed and persists after the LV cavity has 
been filled with contrast, the power should be reduced until 
homogenous opacification is obtained.
WARNINGAlways read and follow carefully the manufacturer instructions 
on the contrast agent label.
CAUTIONToo high Power setting will destroy the contrast agent in the LV 
cavity.

Myocardial Contrast Imaging
The main goal of the Myocardial (MC) Contrast application is in 
the assessment of myocardial perfusion.
The MC Contrast application is pre-configured to give access 
to high power settings of the Coded Harmonic Angio technique, 
which combines the strength of harmonic imaging and power 
Doppler. MC Contrast application shall be used in intermittent 
mode.
WARNINGThis application is intended for clinical research only. Diagnosis 
must not be based on results achieved by contrast analysis 
alone.
