VivoQuantTM
is inviCRO's multi-modality post-processing suite for SPECT, CT, PET, MR and
optical imaging data. DICOM, NifTI, and raw data can be imported as well as
many proprietary formats from pre-clinical imaging equipment. VivoQuant
combines fundamental viewing functionality with powerful tools for fine-tuning
images, isolating and analyzing regions of interest, and more. Multiple display
modes including orthogonal views, slice views, special co-registration
multi-views as well as 3D MIP and volume renderings allow users to optimally
view information of interest. Built-in tools allow the imaging scientist to
extract the information she or he needs with minimal effort.

Tool.
2012-06-06 » News: VivoQuant 1.21 released
inviCRO is excited to announce the release of VivoQuant 1.21. With new and
expanded functionality, the development team has been hard at work to continue
to deliver an image viewing and analysis platform that is more powerful,
flexible, efficient and easier to use for your research needs. VivoQuant users
now have access to a new and improved Distance and Annotation Tool, revamped
iPACS sync and DICOM proxy clients, new VivoQuant sessions feature, improved
data loading and handling of DICOM and non-DICOM image data, expanded
scriptable workflows, and
much more!
2012-03-07 » News: VivoQuant export renderings to Browser
VivoQuant 1.21 now allows the export of ROI renderings to
your favorite (non-IE) web browser.
Thanks to the X Toolkit (XTK), sharing
your ROI data has become even more simple. Now your audience does not need a
VivoQuant license to be able to check out your latest ROIs or Atlas work.
The export is implemented as a VivoScript, using VivoQuant's brand new
ScriptEngine, which means the exported web page can be customized very easily.
Currently, experience is best on Chrome and Firefox, however, also in
Safari you can enable WebGL.
Internet Explorer requires the installation of a plugin.
VivoQuant 1.21 will come with many more VivoScript examples, e.g.
automatic segmentation, a humane rat skinner, export of new movie types, etc...
2011-11-11 » News: VivoQuant 1.20 released
inviCRO is excited to announce the release of VivoQuant 1.20. With new and
expanded functionality, the development team has been hard at work to deliver
an image viewing and analysis platform that is more powerful, flexible,
efficient and easier to use for your research needs. VivoQuant users will be
introduced to a further revamped and improved 3D ROI tool, Bruker and Aspect
Imaging MR data loading support, PET/MR viewing support, scriptable workflows,
expanded DICOM support, and much more!
inviCRO has recently signed
non-exclusive distribution agreements with two leading manufacturers of pre-clinical
MR systems for distribution of VivoQuant as their multi-modal solution for
viewing and analyzing image data.

2011-04-08 » News: VivoQuant 1.19: Welcome to the Third Dimension
inviCRO's latest VivoQuant features the powerful fully 3D ROI tool. For
the first time, you will be able to classify each individual voxel of a three
dimensional volume dataset. VQ will support your segmentation efforts with
easy to use, however, powerful toolbox for manual, semi-automatic and fully
automatic segmentation.
VQ continues to fully support multi-modal and dynamic data, also in the
3D ROI tool. You only have to do the segmentation for a fixed ROI once
and it will be evaluated for all loaded datasets automatically.
Test versions of the new 3D ROI tool are available as
part of our beta testing program (see left Download column).
Manual segmentation tools:
Painting Mode: Use a circle or 3D-sphere tool to classify voxels in
one of the three orthogonal views.
Spline Tool: Use the spline tool to draw and
manipulate ROI shapes, adjust the spline points, add/remove regions in
free hand mode or use the thresholding tool and subsequently push ROI
borders back in or expand them using the Bully.
Any ROI can easily be eroded or dilated to remove or add to the outer
layer of voxels. This tools allows to clean-up images, as well as
compensate for effects such as partial volume or limited resolution.
Semi-automatic segmentation tools:
The 3D ROI tool provides powerful thresholding methods:
Global threshold classifies all voxels within a given value range.
Connected thresholding allows to additionally set a seed point, from
which all voxels in the given range are added to the ROI. Allows easy
segmentation of lungs, of if constricted to a region of Xenograft
tumors or other border regions.
Neighborhood thresholding also applies a connected thresholding,
however, only adds voxels whose neighbors also fulfill the
thresholding condition. This method can be used to efficiently segment
separated compartments such as lungs or the brain.
Fully-automatic segmentation tools:
Histogram-based auto-thresholding allows to
separate any input ROI into foreground and background, e.g. outside air and
body of an animal, or if applied on the body it separates tissue from bone.
Confidence Connected auto-thresholding requires a seed point and
evaluates the voxels in its neighborhood to then add all connected
voxels within a certain variance- and mean-based confidence level.
inviCRO iPACS:
Full integration into inviCRO's iPACS Data Management System and the
automated analysis tools, such as the tumor analysis and atlas-based
brain tools. ROIs and quantification results can be stored and later
retrieved to and from an iPACS with one click. Making it easier than
ever before to exchange and archive (CFR21 part 11 compatible) your
analysis results.
