SRI-HD No SRI-HD (Speckle Reduction Imaging High Definition) is an
adaptive algorithm to reduce 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 SRI-HD level. SRI-HD is available in 2D
imaging and may be used with any transducer or clinical
application when image speckle appears to interfere with
the desired image detail.
LOGIQView (Option) No LOGIQView provides the ability to construct and view a
static 2D image which is wider than the field of view of a
given transducer. This feature allows viewing and
measurements of anatomy that is larger than what would
fit in a single image. Examples include scanning of
vascular structures and connective tissues in the arms
and legs.
LOGIQView constructs the extended image from
individual image frames as the operator slides the
transducer along the surface of the skin in the direction of
the scan plane. The quality of the resulting image is
somewhat user-dependent and requires some additional
skill and practice to develop proper technique and
become fully proficient.
LOGIQView is not available for the following: Multi Image,
Timeline Modes, Color Flow Mode or PDI Mode.
