Open Data

The first data set loaded into VQ is termed the Reference and is so named because it is often a CT image used for anatomical reference. When loading multiple data sets into VQ (i.e., from the Data browser), VQ recognizes CT data and automatically sets it as the Reference. VQ is capable of handling several file formats.

Getting There

Three different methods exist for opening data.

The first method is to use the "Replace Data" or the "Append Data" thumbnails in the Main Window.

The second method is to go to "Open Data" under the File menu.

The third method is to use the keyboard shortcut "Ctrl+O". For more on keyboard shortcuts in VQ, please see Keyboard Shortcuts.


Selection of the "Open Data..." option opens a navigation window from which the Reference data set may be selected.

File Formats

VQ can handle a variety of file formats. The default options include

  1. DICOM: *.dcm, *.dicom, 1.*
  2. TRaster: *.ras, *.res., *.bin
