9.5.15 3D Vector Volume Plot
When you want to create 3D vector volume plots of the anal-canal, you need a
catheter with at least three radially oriented channels. To display the plot,
profile tests must have been performed. Also, the pressures should be
correctly defined in the channel definition ( Settings > Channel definition ).
In the analysis software, click the 3D Vector volume plot button to display the
3D vector volume plot. Three-dimensional imaging of the anal sphincter can be
used to evaluate sphincter dysfunction.
Figure 9.32 Dimensional Vector volume plot
The 3D vector volume plot is created from the pressures measured during the
pull-through of the catheter through the rectum. The profile is divided in
several segments of fixed length. The maximum pressure in each segment for
each channel is used to draw the three-dimensional sphincter image.
The Vector Volume Plot of the sphincter is displayed in the left window. It can
be rotated in any direction by means of the cursor keys or the mouse. The 3D
