DDP (Data Dependent Processing)
Performs temporal processing which reduces random noise
without affecting the motion of significant tissue structures. An
index number is displayed in the status window (under Proc) to
indicate the relative DDP level.
Contour/Edge Enhance
Controls image processing related to the extent of edge
enhancement applied to an image.
Diff On/Off
Affects the level of reverberations in the image. When turned
On, the frame rate (or the number of focal zones) will decrease,
while the reverberations will be attenuated. (Applicable only for
cardiology applications).
Power
When power is re-
duced, it reduces
the signal-to-noise
ratio, so that the im-
age may become
noisier.
Controls the amount of acoustic power applied in all modes.
When power is set to maximum, it is equal to or less than the
maximum acoustic power permitted by the FDA. The Thermal
Index (TI) and the Mechanical Index (MI) are displayed on the
screen.
Ultra Definition (UD) Clarity
This control is effective in Cardiology applications only. This
control reduces the unwanted effects of speckle in the
ultrasound image. Image speckle usually appears as a grainy
texture in otherwise uniform areas of tissue. Its appearance is
related to image system characteristics, rather than tissue
characteristics, so that changes in system settings, such as
probe type, frequency, depth, and others, can change the
appearance of the speckle.
Too much speckle can impair image quality and make it difficult
to see the desired detail in the image. Likewise, too much
filtering of speckle can mask or obscure desired image detail.
Extra care must be taken to select the optimal Speckle
reduction level.
Ultra Definition (UD) Speckle Reduce
This control is used to reduce the amount of speckle in
non-cardiology applications.
