Hello, my name is Johanna Maack.
I am a Senior Clinical Application Specialist with Philips Ultrasound.
In this video you will see a
demonstration on how to acquire a GYN volume.
After the video you will be able to acquire and manipulate a data
set of the uterus and / or ovary.
Volumetric acquisitions, which is stored allow the
offline review, manipulation and analysis of the data set to
obtain the maximum information from a study.
It allows the assessment of a variety of gynecological
disorders, including uterine anomalies,
intrauterine device location,
endometrial disorders, fibroids, and ovarian pathology.
First we need to optimize our 2D
image. An optimized 2D image provides a higher
resolution 3D data set.
We can do this by pressing iScan that, optimizes 2D Gain and
TGC. Or adjust settings such as XRES, 2D Opt,
Dynamic Range,
Depth, and Focus.
Now push the 3D knob.
On the touch screen you can select 3D or 4D.
3D is selected by default.
By default there is no region of interest or ROI box on your
image. You can acquire a 3D data set immediately by
pressing the middle button above the trackball
or Start 3D on the touch screen.
If a ROI is needed, press Standby on the touch screen
or the middle button above the trackball and then
3D ROI on the touch screen.
On the bottom of the monitor you will see three options below the
trackball diagram. 3D ROI
Position, 3D ROI Curve Adjust,
and 3D ROI Size.
By pressing the buttons on the left and right of the trackball,
you can go through these options and set the Position,
curve the volume view line, and change the size of your
region of interest.
Press Reset Curve to return the volume view line to a straight
line, if needed.
Make sure to include all anatomy needed in the ROI box.
Further settings can be changed to increase the resolution of
the 3D data set.
Adjust the angle if a bigger or smaller sweep is needed.
The 2D opt can be changed to
Res. A Gen and Pen setting is
also available. On the second page of the touch screen,
changes can be made to Chroma map and or the Gray map.
Press 'Start 3D' on the touch screen or the middle
button above the trackball to start the acquisition.
Press 'Standby' on the touch screen or the middle button
above the trackball if you want to reacquire the data set.
On the monitor you see the sagittal transfers and coronal
Plane of the uterus, as well as the volume image numbered from
one to four.
To manipulate the data set at a later time, press save 3D on the
touch screen. Another option is to save the three MPR planes
sweeps as cine loops.
On the second page of the touch screen, press 'MPR Save'.
And then 'Save MPR's'.
The active plane is surrounded by a yellow box, and on each MPR
plane we have a region of interest box indicated by the
Red, Green and blue boxes.
The dotted line indicates where the volume image comes from. The
direction of the volume view.
On the bottom of the monitor around the trackball diagram you
will see the options available for the left and right buttons
next to the trackball.
Use these buttons and the trackball to change the
position. The size of the ROI box or the curved line.
For example, if I want to change the ROI size on the transverse
plane, I will select the transverse plane number 2 on the
touch screen. Use the buttons next to the trackball, select
3D ROI size and move the trackball up and down or left and
right to change the box size.
Let's take a look at how we can manipulate the MPR planes.
If needed, we can hide the volume image by pressing hide
volume on the touch screen.
To find the area of interest, you can slice through a
specific plane by selecting the plane on the touch screen
and turning the Slice knob.
Or turn the X, Y and Z knobs to rotate a specific plane.
At anytime you can press 'Reset Orientation' on the touch screen
to return to the original
orientation. To see an area of interest in all three MPR
planes, move the cursor with the trackball to the area
of interest.
MPR touch can also be used to manipulate the reference cursor
on the touch screen.
If we did not hide the volume, use the pointer to activate
the yellow cursor and move it to the area of interest.
Press pointer again to go back to the 3D ROI options.
Manipulating the volume image.
Optimize the ROI boxes to see the desired volume Image, using
the trackball buttons next to it to adjust the size, position
and curve line of the ROI boxes.
MPR touch can also be used.
Select the 1-Up layout on the touch screen to view the volume
image only. Press 'Rotate' to rotate the volume image.
Or 'Quick Flip' if needed.
Rotate the X, Y and Z knobs to align or the Slice knob to slice
through the volume image.
Here you can also press 'TouchVue' to manipulate the volume image
on the touch screen.
Different rendering options are available for the volume image.
Press 'Vision' on the touch screen to see different options.
The TrueVue vision have a light source that can be moved
anywhere in your volume image and by turning this rotary knob
you can change the light depth.
Using TouchVue you can manipulate and zoom the image.
With one tap on the touch screen, you can move the
light source or change the depth using this rotary knob.
Threshold, transparency and
smoothing, can be used to optimize the volume image.
Select these on the touch screen or press the rotary
knob to select and then turn the knob to adjust.
On the second page of the touch screen Volume Chroma, Lighting
and Bright is available, if further optimization is needed.
Let's go back to a 4-Up layout
The dotted line or volume view can be changed depending from
which direction you want to view
the data set. Press 'Volume View'.
Notice how the dotted line changes position in the ROI box.
Unneeded information can be erased from the volume image if
needed. Select 1-Up under layout to display
the volume image.
On the touch screen press 'Sculpt'.
At the bottom of the monitor you have the option between 3D
Sculpt, and 3D Erase.
With 3D Sculpt you see a green cross on the volume image.
Move the cross to where you want to start removing information
and press the middle button above the trackball.
Move the trackball and draw the line around the information you
want to delete and press the middle trackball button again.
Select 3D Erase.
With the button next to the
trackball. A grey dot appear on
the volume image. Move the dot to where you want to remove the
information and press the middle button above the trackball.
Slowly move the trackball to remove information from the
volume image.
When you removed incorrect information, press 'Undo' on the
touch screen to get the
information back. When done,
press Close. Sculpt is also available when
you are in TouchVue.
For 3D and 4D acquisitions, different settings are needed
depending on the anatomy that you are looking at.
After you have optimized your dataset an volume image. You
can now save your setting, which include multiple 3D, an 4D para
meters by Pressing 'Save 3D Preset' on the touch screen.
Provide a name for your preset and you can
directly use this in the future with all your
settings saved. For example, an acquisition of
the uterus or ovary.
Additional functions includes Alt Print. This can be
programmed to a printer.
GI3DQ is a QLab application to manipulate the data set.
QLab is also available, off cart.
iSlice, the possibility to get it tomographic view
of the volume.
Thank you for watching. On how to use our FlexVue Option, please
refer to the FlexVue Video.
