Caution Statements

This Chapter reviews the most important information for the safe operation of the VesselIQ Xpress

software. Please review this documentation before using the software.

Geometric Accuracy

The Lumen and 3D views that are displayed and created using the CardIQ Xpress Pro softwareshould be used for orientation purposes only, NOT for diagnostic purposes.

When creating the Lumen view within CardIQ Xpress Pro, it is necessary to change the threedimensional centerline into a straight line. This transformation results in a degree of geometricdistortion of the anatomic features displayed in this view. Use the correlated 2D views to verify

findings.

The 3D views, can be clipped to clearly show the vessel being analyzed among the surroundingtissue, and may not include all vascular anatomy.

The distance, angle and area measurements created in this software are only accurate if all thesegments used to create the measurement are longer than the inter-slice distance of the data setbeing used.

6/30

GE Healthcare

Vessel Quantification and Tracking

The accuracy of vessel quantification and tracking is highly dependant on, image quality, imageresolution, inter-slice distance, artifacts, pathology, and contrast enhancement.

It is the responsibility of the user to verify the results of the tracking and quantification of the lumensegments before using the data for diagnosis.

In case of incorrect tracking or quantification, the user must use the provided edit centerline andedit section tools to make any corrections necessary.

Accuracy of cross sectional distance measurements should be +/- 10% for vessels with a diameterbetween 10 and 20 voxels. It should be +/- 5% for vessels with a diameter greater than 20 voxels.

Accuracy of cross sectional area measurements should be +/- 40% for vessels with a diameterbetween 10 and 20 voxels. It should be +/- 20% for vessels with a diameter greater than 20 voxels.

Accuracy of volume measurements should be +/- 40% for vessels with a diameter and a lengthbetween 10 and 20 voxels. It should be +/- 20% for vessels with a diameter and a length greaterthan 20 voxels.

Accuracy should be better than +/- 10 degrees for angle measurements.

To access the accuracy of the measurements performed with the Volume Viewer 3 application,please review the section titled, Measurement Accuracy in the Volume Viewer 3 user guide.

Vessel Quantification and Tracking (cont.)

In exams with very tortuous vessels, and/or severe pathology, the automatic centerline algorithmmay not always follow the true path of the vessel lumen. The user should always examine andverify that the computed centerline tracking is accurate otherwise the user if necessary correct theresult either by modifying the centerline via the edit centerline tool, or add intermediate trackingpoints and repeating the centerline detection process.

Saving and Filming Images

After archiving/saving images and before leaving the application, always verify that the archivedimages are correct by reviewing them in the viewer.

Before archiving images used for diagnosis, verify that the image orientation annotation and thepatient information is displayed correctly.

CardIQ XpressTM Pro WorkflowStep What you select How or Why you select it

1 The Cardiac Vessel Analysis protocols are

built with a step-by-step guide. Theworkflow for the protocols is basically thesame, however some protocols will vary inthe number of steps.

The guide will contain both the instructionson how to perform each step and thenecessary controls (buttons, menus, etc).

The user should read the CardIQ XpressTM Pro UserGuide in addition to this quickstep guide, as thisdocument will not cover all features.

(For this example, we have used the Angiographicview protocol)

1(cont.)

Step 1: Angiographic View Selection

Step 1, enables the user to make anynecessary edits to the 3D MiP image that isautomatically segmented by the software.

The tools available on this panel are theAuto Select tools that allow the user togrow or add back into the 3D MiP modelany structure, or vessel that was removedduring the segmentation process.

In addition, the user may send theangiographic view directly to the CardiacReport by using the Sent to Reportbutton. This will generate six separateviews angled in predefined positions to

simulate cath views. This will be added tothe Reporting Tool software which cangenerate a separate document as thereport.

(Refer to the CardIQ Xpress Pro User Guide fordetailed instructions)

vessel, simply left click the next vessel onthe list, then place your point.

To undo a deposited point, click on thecheck mark in the box corresponding tothe vessel. Then redeposit the point in thedesired location.

Hints:

Placing the point in the center of thecontrast enhanced lumen on the 2D views,

produces better tracking results, thanplacing the point on the 3D views.

When placing the points, place the point inthe distal portion as far as you want thevessel to be tracked

3 Step 3: AVA Tools:Edit/Measure

At Step 2, the screens update to display the

curved, lumen, oblique, x-sectional, andsegmented Volume Rendering views foreach branch traced. The views will bedisplayed based on the default layout forthe protocol.

At this step, the user should review eachbranch of interest by rotating around thecurved view, reviewing x-section andlongitudinal views.

(Refer to the CardIQ Xpress ProTM

User Guide forViewport control instructions)

The user should verify that the software has:

Identified the vessel correctly

Quantified the vessel cross-section at eachlocation of interest correctly
