LOGIQ C5/C5 PRO Quick Guide
Easy 3D
Acquiring a 3D Scan
1. Optimize the B-Mode image. Ensure even gel
coverage.
2. Press the 3D control panel key. Two screens
appear.
3. To start acquiring the image, press 'L' (the left
split screen key).
4. To perform a parallel scan, scan evenly. To
perform a sweep (fan) scan, rock the probe
once. Note the distance of the scan.
5. The 3D volume of interest is dynamically
assembled on the left side of the screen.
NOTE: If the image stops before you're done
scanning, start acquiring the 3D volume of interest
again.
6. To complete the 3D scan, press 'R' (the right
split screen key).

Manipulating the 3D Scan
Imagine you are able to manipulate the 3D volume
of interest (VOI) in your hand.
You can rotate it left to right or right to left. You can
rotate it forward/backward (white hand).
Then, imagine that you can view the volume of
interest one slice at a time through the anatomy
(red hand).
Also imagine that you are able to pull back tissue to
view specific portions of anatomy (yellow and green
hands).
The 3D volume of interest is a tangible anatomical
object that you can see and manipulate easily using
the Trackball and Set control panel keys.
Practice positioning the pointer at different places
within the 3D volume of interest. Highlight different
colors, press Set to select this volume for
manipulation. Use the hand to move the 3D volume.
Adjusting the 3D Volume of Interest
You can colorize the 3D volume of interest.
You can resize the VOI by adjusting the scan
distance.
Performing a Surface Render
From the 3D Touch Panel, press 3D, then press
Texture on the left menu to add a photorealistic/
clay-like quality to the render.
Adjust the opacity and density via Threshold/
Opacity (press the key to adjust opacity). This
adjusts which 'grays' the system recognizes,
allowing you to emphasize/de-emphasize grays as
necessary.
Scalpel
To scalpel away portions of the anatomy,
1. Press Scalpel. A caliper appears on the 3D
VOI.
2. Press Set to set the caliper. Trackball around
the portion to be cut away.
3. Double click and apply the scalpel.
4. Change the projection and scalpel again.
NOTE: You can undo one scalpel movement (the
last one).
3D View Scanning Hints
Set the appropriate values for the 3D Acq Mode
and Scan Plane.
It is advisable to set the scan distance before the
scan begins.
