For analysis, it is necessary to build a centerline which is automatically located in the notional center of the vessel. Only one centerline can be built at a time. To save the built line and build a new one, bind it to a specific vessel from the list in the left part of the window (see Section 7.1.1).

You need to control the process of building the centerline and make corrections, if needed. |

You can build the centerline in three methods. To select a method click the arrow on the right side
of the New Vessel button and select the appropriate method. The current method is marked
with a flag.
If the centerline for the selected points cannot be built, then the message Centerline building has failed appears.
The DICOM Viewer adds the required number of intermediate points to set the centerline. For more accurate positioning of the line, move these points manually with the mouse while holding the left button.
If the line is not completely built, then select the point up to which you want to extend the line and click in at it. The line will be built from the nearest existing point.
If the line is not built correctly, then start building it again by clicking on the New vessel
button or delete part of the line. To delete part of the line, delete a segment. The segment is deleted
along with the shorter part of the line adjacent to the point.
To delete a segment, right-click on the first point of the segment and select the Remove segment item. The shorter part of the centerline is removed from one side of the point and the section between this and the next point from the other side.
To delete a point, move the cursor over this point so that all the points are highlighted, right-click and in the context menu and select the Remove point command.
To add a point, move the cursor to the place where you want to add a point, right-click and in the context menu and select the Add point command. The centerline will change so as to pass through a new point.
The initial research data or the volume reconstruction data can be used for building. To select the
data source, click the arrow on the right side of the New vessel button and select the
appropriate source.
The centerline is shown in Fig. 7.3.
