Note: Measurement error is within 5% of the distance you
measured for all linear probes.
Hint: When you scan, scan slowly and in a uniform motion
lengthwise, end-to-end (with or against the probe orientation
marker). LOGIQView acquires images via leading edge vectors
(and does not acquire slices, as in CINE). The image is being
stored as you perform the scan and you can watch the
LOGIQView as it is being acquired.
Uniform Motion
The quality and usefulness of LOGIQView images is affected
by transducer motion. Incorrect technique can contribute to
image distortion.
Guidance and precautions for uniform motion:
• Continuous contact is required throughout the length of the
extended image. DO NOT lift the transducer from the skin
surface.
• Always keep the transducer perpendicular to the skin
surface. DO NOT rock the transducer.
• Keep the motion within the same scan plane, if possible.
DO NOT slide the transducer laterally.
• Lateral turning (change in direction to follow anatomical
structure) can be accommodated with slower motion. DO
NOT make abrupt changes in direction.
• The system accommodates a reasonable range of motion
velocity. DO NOT make abrupt changes in speed of motion.
Deeper scans generally require reduced speed.
Compound
Compound is a process of combining several frames from
different steering angles into a single frame. The combined
single image has the benefits of reduced speckle noise,
reduced clutter, and continuity of specular reflectors. Therefore,
this technique can improve contrast resolution.
Compound is available with linear and 4C-RS curved probes in
2D live mode, or in the 2D image while in Color mode.
Compound is on by default.
