Multi-series (4D) Viewer

When a contrast agent is used, the radiologist usually does not make a diagnosis based on a single volume but on the series of volumes that show the temporal flow of the contrast agent. Especially for MR  applications like dynamic contrast-enhanced MRI (DCE-MRI) (and to a certain limit also for CT applications) it is very important to look at the full 4D series. The Multi-series (4D) Viewer is designed to cover this requirement.

The Multi-series (4D) Viewer is accessible via the menu command "UtilitiesAdvancedMulti-series (4D) Viewer".

Viewing Modes
The Multi-series (4D) Viewer has two viewing modes: The Normal Mode and the Tiles Mode. The Normal Mode always displays the active frame of the active series, and the Tiles Mode always displays the active frame of all series simultaneously. The user can enable or disable the Tiles Mode by pressing the "tiles mode" button () of the Main Toolbar. The main toolbar has buttons that allows you to navigate between series and frames.
