TissueQuest Analysis Software

TissueQuest analysis software for fluorescent markers

TQ Logo 2017 V2 small Analysis of fluorescent markers

TissueQuest provides three analysis modes:

  • Cell-based (nucleus, cytoplasm, membrane)
  • Stained areas
  • Small dots (e.g. FISH)

Context-based analysis can be done by manually drawing regions of interest. TMA can be analysed and also detected on imported files.

automation profile icon Analysis profiles can be created and used for automated analysis.

TissueQuest is integrated into the following :

Standalone  TissueQuest is also available as a standalone software.

 Importer  TissueQuest has  for the following digital image or slide formats:

  • 3D Histech (.mrxs)
  • Hamamatsu (.ndpi)
  • Zeiss Axio Scan (.czi)
  • Perkin Elmer (.qptiff)
  • Images (.jpeg, .tif, .bmp, .png)

Images to be analysed in TissueQuest must be provided as 8 bit monochrome greyscale images (one image per channel). Overlay (colored multichannel) images CAN NOT be analysed.


 

New TissueQuest 6.0 - the easy solution for immunofluorescence analysis

TissueQuest is an image analysis software for the FACS-like analysis of samples stained with immunofluorescent stains.

TissueQuest can analyse images from epifluorescence as well as those from confocal systems.

New features in TissueQuest 6.0

TissueQuest 6.0 comes with new features which improve handling of large samples/number of samples in one project as well as increase the softwares speed:

Full 64 bit support will greatly increase the number of samples which can be analysed in one project.

The latest processing libraries have been integrated which will increase processing time by up to 40%.

The cache from TissueFAXS projects will be used, this eliminates wait time while the project is loaded into the viewer.

Fluorescence shading correction

Finally, TissueQuest has a heatmap feature in scattergrams.

HistoQuest 6.0 new heatmap feature

This feature will show areas of objects density in the scattergram which may not be visible in highly populated scattergrams and so deliver more information when working with them.

HistoQuest walk away automationTissueQuests fully automated template based analysis is optimised for clinical routine and research applications and allows complete walk away operation.

The user just has to load samples into an analysis project and to manually define regions of interest, if any are wanted. Then the template can be loaded.

It provides:

  • The segmentation settings for all objects to be detected
  • The method for dealing with events in ROI
  • The markers
  • The diagrams from the first sample of the project from which the template was saved
  • The statistics report settings
  • The simple report settings
  • The small dots settings (if any)

After this, analysis can be started.

 

TGs hidden power - Tissue Cytometry technology

TissueGnostics introduced Tissue Cytometry technology into image analysis software more than a decade ago with TissueQuest software in its first version

While, at a first look, it may appear to be just another form of displaying data, there is much more to it.

Combined with segmentation images it is also a simple and intuitive tool to visually validate results. TG calls this "Backward Gating" and "Forward Gating".

TissueQuest Forward Gating and Backward Gating feature

Morphological Filtering using Tissue Cytometry technology combined with appropriate planning of the analysis provides a highly flexible and capable instrument for extracting specific data from a sample (see image below).

TissueQuest Image Analysis algorithms

TissueQuest uses algorithms for nuclear and cell compartment segmentation. It also provides an algorithm for stained area detection as well as algorithms for the detection of dots inside of already detected cell compartments.

The nuclear segmentation algorithm is highly efficient in difficult situations in tissue and can be set with two values only - mean nuclear size and nuclear channel background threhshold. The cell compartment algorithm provides a large amount of flexibility with a few simple settings (see below, yellow=segmented nuclei, blue nuclei positive for DAB or cytoplasm positive for Permanent Red marker).

The image below shows segmentation and the use of Tissue Cytometry technology to automatically identify colocalisation.

Segmentation on Plakoglobin

 

The Total Area algorithm segments stained areas in a sample (see image below).

TAM on nerves

 

The small dot algorithm provides small dot detection ideal for FISH and other applications in which the quantification of small objects within cellular compartments is needed.

The image below shows the quantification of FITC and Texas Red FISH dots inside of the nuclear compartment.

Tissue Microarray Analysis support

TissueQuest fully supports the analysis of Tissue Microarrays scanned either with TG TissueFAXS systems or those slide scanners for which TissueQuest provides importers

 

Flurescence TMA composite

For analysis projects of scans coming from TG TissueFAXS systems the autodetected TMA regions will be imported.

For scans imported from other scanning systems without detected regions the TMA autodetection feature is also available in TissueQuest.

 

TissueQuest Data Export capabilities

TissueQuest provides four modes for the export of analysis data, ranging from simple prefabricated reports for internal presentations to selective data export from all analysis projects from a complete scientific project.

TMA report   TMA export 

There is a special pathology oriented data export feature for the small dot algorithm data, which has been buit according to pathologists requirements for FISH analysis.

Routine pathology oriented list display

All TG data export modes write data to Excel, CSV and pdf formats.

 

Other TissueQuest features

TissueQuest features include a registration and comparative analysis capability for differently stained consecutive samples.

Compare sets provide grouping features for multiple scattergrams and histograms as well as overlaying them.
