The Phase Rotation process allows you to apply a phase rotation to the volume data.

Phase rotation of values other than 0 or 180 degrees is computationally-intensive. The resulting output volume may be very slow to use, particularly when viewing time-slices and amplitude extractions. To avoid performance issues, export the result volume to dugio format (see Exporting a Volume to DUG I/O) and use it instead.

Create a phase rotation process

Create a phase rotation process
  1. In the Control Panel, open the Process tab.
  2. At the tab header, click the Add icon and select New Process.
  3. Double-click Phase Rotation.
  4. Type a name for the process and click OK.

Define settings for phase rotation

Define settings for phase rotation
  1. In the Details Panel at Volume, select a volume in which the phase rotation will be applied.
    Note: You cannot apply phase rotation on a depth volume. However, you can do so by first converting the volume to time (TWT) domain using the Volume Resampling process or exporting the volume to time domain as described in Exporting a Volume to DUG I/O.
  2. Type the rotation degree at Degrees. Acceptable value is between -180 and 180 degrees.

As a result of this process, a new phase rotation volume is available in the Volume tab.

Tip: To quickly open the output volume, right-click the process item in the Process tab and click Open Child Volume. Vice versa, you can also open the process from the Volume tab directly. To do this, right-click the volume which was created from the process (indicated in italics) and click Open Parent Process.
