Volume Display Settings

The Volume Details Panel includes settings that affect the display. Additional settings are controlled by the selected class for the volume.

Show the volume details panel by selecting the volume in the Volume tab of the Control Panel.

Displaying as density and/or wiggles

Show density and wiggle for volume

Density

Enable Density to display the volume as variable density or colour filled based on amplitude. Colours are determined from the colourbar chosen in the Class.

The following hotkeys are available:

  • F5: Reduce the clipping range making the image "hotter"
  • F6: Increase the clipping range making the image "cooler"
  • F4: Reset the range to its default settings
  • F7: Change colours to the next default colourbar (Shift-F7 use the previous)

Wiggle

Select the Wiggle check box to display traditional wiggles in the section views. The settings for wiggles display are adjustable in the Class setting (see Defining Wiggle Settings).

Tip: Enable the Density and Wiggle together to overlay wiggles on a filled display.

Displayed data value range

Override min and max from class settings

In most cases, use the class settings to set the minimum to maximum value range - the “clip” values.

To override the minimum / maximum values, disable the “From class” box. This is useful to display two volumes with the same class with different amplitude ranges.

When loading volumes, Insight estimates the value range of the data. If the estimate is different from the class range, the range is overridden using this setting.

Note: If the class is symmetric, the Min field is disabled. It is automatically set to the negative Max value.

Gather volume settings

  1. Maximum number of bins: Specify the maximum number of bins to use when counting the data points.
  2. Logarithmic: Select to display the histogram on logarithmic scale. 
  3. Min Value, Max Value, and Location: This section displays the minimum and maximum bin values, as well as location information for the histogram.
  4. Line: Displays available lines for 2D volumes. Export min/max values for a particular line or all data to a CSV file by right-clicking the Line field.
  5. Screen Capture: Click to capture an image of the histogram (see Taking Screen Captures).
