image area. To play or pause the loop, do any of the following:
• Move the pointer over the image and press the spacebar.
• Use the Play or Pause controls in the cinebar.
3 Studies
Studies (PC Version of QLAB Software)
The information in this section extends and enhances the information contained in the user
information provided with the QLAB software. Be sure to read the user information provided
with your QLAB software and strictly observe all warnings and cautions.
For more information about working with studies, see the QLAB Help or the QLAB User Manual.
4 Auto 2D Quantification
The information in this section extends and enhances the information contained in the user
information provided with the QLAB software. Be sure to read the user information provided
with your QLAB software and strictly observe all warnings and cautions.
For more information about the a2DQ Q-App, see the QLAB Help or the QLAB User Manual.
Auto ROI
Automated border detection (Auto ROI) is not available on image loops acquired by Philips
pediatric and TEE transducers.
aTMAD Workflow
The aTMAD workflow uses automated tracking that is applied to all frames in the image loop to
track the location of the midpoint of the annulus through the current beat.
a2DQ Fundamentals
Auto Tissue Motion Annular Displacement (aTMAD)
The Auto Tissue Motion Annular Displacement (aTMAD) workflow provides global cardiac
quantification based on angle-independent tracking of the cardiac valve's annular motion
through the current beat.
NOTE
For information about working with exam protocols, see the Help for your ultrasound system.
When you load one or more of these views into the a2DQ Q-App, the appropriate ROI template
is selected automatically as you move from view to view. All you need to do manually to
quantify each view is:
• For the AP4 and AP2 views, set the annular and apical points.
• For the SAX M view, fit the ROI to the myocardium.
a2DQ Workflows
aEF-FAC Region of Interest Tasks

7 Cardiac 3D Quantification
The information in this section extends and enhances the information contained in the user
information provided with the QLAB software. Be sure to read the user information provided
with your QLAB software and strictly observe all warnings and cautions.
For more information about the Cardiac 3DQ Q-App, see the QLAB Help or the QLAB User
Manual.
WARNING
A foreshortened left ventricle in the MPR views results in inaccurate volume calculations.
Cardiac 3DQ Advanced does not calculate mass.
GI3DQ Controls
Measurements and their corresponding results and mesh appear in the same color. This feature
enables you to easily identify which measurement corresponds to which result and to which
mesh.
Advanced Measurements
The following control is available, in addition to those listed in the QLAB Help.
Name Description
3 Distance Volume Activates the tool for calculating volume derived from
three distance measurements.
GI3DQ Fundamentals
Image Presentation Views
The GI3DQ controls provide a variety of combinations for the presentation of image data. The
options are distributed among the View, iSlice, Trim/Crop, and Image Adjust tabs.
Disregard references in the QLAB Help to the Volume and MPR tabs.
Slab
The Slab option is on the Trim/Crop tab.
Slice Plane
The Slice Plane option is on the View tab.
Navigation Guides
The MPR X-Hair options are on the View tab. Disregard references in the QLAB Help to the
Volume and MPR tabs.
iSlice View
The iSlice view presents the source MPR as a series of slices. You can select the source MPR for
the slices, the layout of the slices, the depth and interval of the slices, and the number of slices.
The orthogonal MPR views display the guides for the slices, as shown below. When the number
of slices exceeds the display grid, the presentation indicates the visible slices using solid lines
and the slices outside of the displayed grid appear as dotted lines. You can move the grid up
and down the slices or increase the number of slices shown in the grid.
The 3D Volume view is replaced with a grid, the size of which is determined by the Layout
selection. The Layout grid sizes are: 2x2, 3x3, 4x4, and 5x5. Depending on the number of slices
you have set, you may see some or all of the slices. You can use Slice Up and Slice Down to
change the slices displayed in the grid. Slice Down moves the slices closer to the first slice. Slice
Up moves the slices closer to the last slice.
Each image in the grid is numbered and the number corresponds to the slice guide numbers.
The Depth (mm) control sets the location for the first slice. As you decrease the depth, the first
slice moves towards the transducer position in the Source control. As you increase the depth,
the first slice moves away from the transducer position in the Source control.
The Interval (mm) control sets the width of the slices. The slices are equal widths. The Interval
(mm) multiplied by the Slices gives you the entire width of the series of slices. For example: An
image with Slices set to 10 and Interval (mm) set to 3.5 mm has a total slice width of 35 mm.
You can set the number of Slices to any value between 4 and 30.
GI3DQ Procedures
Selecting a View
You can organize the presentation of image data by using the Layout optimization controls.
1. Click the iSlice tab.
2. Click the Layout (2x2, 3x3, 4x4, or 5x5).
GI3DQ Results
The following results are available, in addition to those listed in the QLAB Help.
Name Description
Dist 1 The length in cm
Dist 2 The length in cm
Dist 3 The length in cm
Volume The volume in ml, derived from the three distance
measurements.
