Open Reference 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 DICOM browser), VQ recognizes CT data and automatically sets it as the Reference. VQ is able to handle several file formats.

Getting There

Three different methods exist for opening Reference data.

The first method is to use the Open Reference thumbnail in the Main Window.

The second method is to go to "Open Reference..." 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 Reference..." 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
  3. Raw: *.raw
  4. Image Files: *.png, *.tif, *.tiff, *.jpg, *.jpeg, *.bmp
  5. Other: *.img, *.nii, *.mhd, *.mha, *.fdf, *.dc3, *.vol
There also exists an option for displaying "All Files" and not just those with the above formats.
