IVUS longitudinal viewer
The IVUS long viewer shows a longitudinal view of an intravascular ultrasound (IVUS) recording. The longitudinal viewer is part of the 'Rubo DICOM viewer' and can be opened via the image window.
By default, the long viewer will be opened and attached to the image window, when viewing an IVUS run. See 'Settings / Image window' to change the 'IVUS long view' settings.

Change the cross-cut of the IVUS long viewer by assigning the IVUS cut tool to one of the mouse button. Click in the image window at the position the cross-cut should be. The red arrow indicates the cut line and in which direction (top down) the data
is displayed in the long viewer. When you hold the mouse button down, a red square is displayed in the long viewer, indicating the position of the mouse pointer in the image window.
See the image below, where the cut-tool is assigned to the left mouse button.
