StrataQuest
Context-based Analysis

StrataQuest is TGs most advanced image processing solution for both brightfield and fluorescence images. It provides features such as detection of tissue structures, nuclei/cells, cellular compartments, measurement of proximities and spatial relationships on a digital slide. It integrates detected objects into detailed context-based quantitative analysis.

There are over 50 StrataQuest Apps which can be used for automated analysis and the number is constantly growing.

StrataQuest Apps
The Easy Solution For High-Level Image Analysis 

A StrataQuest App is simply an analysis solution for a specific task. It is complete up to the point of providing the specific analysis results ready to be exported to, e.g., Excel or CSV formats. This is complemented by an export function for all images from the software. The core feature of an App is a simplified, tabbed "Easy Mode" user interface. While an App is meant to be run by simply clicking the "Analyse" button, the interface allows the user to make adaptations to sample/staining variance if necessary. TGs decade-long experience in providing analysis solutions to the biosciences market has taught that vaunted "only one click" products work - but only on the textbook quality image on which they are presented.

Advanced StrataQuest

StrataQuest advanced features allow more experienced users to build their own solutions. The ideal tool to do this is StrataQuests logically structured Advanced Mode interface and highly adaptable sample viewer. Solutions created in Advanced Mode can be given an Easy Mode interface and saved as APPs for others to use. This capability, together with the possibility to plug in Matlab, ImageJ and FIJI solutions also make StrataQuest an ideal tool for imaging core facilities.

New Features in StrataQuest 7.0 & 7.1

The new features of StrataQuest 7.0 & 7.1 include improvements to the analysis workflow, management of multiple diagrams, image visualization, and the user interface. Here are some highlights:

  • 7.1 Introduction of “Quick Actions”: This is a new StrataQuest feature used to combine frequent operations in a single action. There are multiple Quick Actions types based on the context from which they are triggered (Layer, Engine, Diagram (quadrants and gates)).
  • 7.1 New engines: improved “Remove Objects”, “Membrane Measurements”, “Events centroids”, “Distance Map – inside”, “Assign classes to objects”, “Background Removal”, etc.
  • 7.1 Image only feature allows visualizing only the image within the viewer in a full screen.
  • 7.1 New intuitive Tissue Detection parameters/layout.
  • 7.1 Improved interface for: “Dots Measurement”, “Membrane Measurement”, “Virtual Channel”
  • 7.1 Show diagram button: allows showing/hiding the Diagrams section.
  • 7.0 Improved image display settings: a new channel histogram has been added for easier signal detection (image on the right). Lower and upper thresholds can be adjusted more intuitively by drag and drop.
  • 7.0 Nuclear Segmentation Engine can now be used in real time, change parameters and see their effect live.
  • 7.0 New deep learning-based Nuclear Segmentation Engine for a more precise nuclei detection.
  • 7.0 New engines for workflow simplification: Tissue Detection Engine, Background Removal Engine, Proximity Areas Engine, Projection Engine.
  • 7.0 comes with new visualization modes including pseudo IHC, providing a pathology view (pseudo coloured images) as well as the HDR-like mode (high dynamic range) and a smoothen image function.
  • 7.0 Improved function and/or user interface of various SQ tools (Layers Editor, Image Types, Image display settings, Manage Diagrams, Manage Gates, Basic Operations Engine, Dot detection engines, scoring function…).
  • 7.0 Z-stacks and Time-lapse are now visible, and individual stacks and time frames can be analyzed.
  • 7.0 Our powerful Classifier Engine allows to distinguish morphologically different regions (e.g tumor and stroma) by simply marking a few characteristic areas.
    7.0 TissueFAXS integrated automatic scanning (dual TF-SQ multitask workflow).
  • Optionally, 7.0 comes with a new image crops feature for scattergrams. Instead of dots, crops of the analyzed objects can be displayed in the scattergram.
  • 7.0 Data compare sets feature from HiQ and TQ is now also available in SQ.
  • 7.0 Easy to use Lambda Stack Navigation function.
  • 7.0 Another new feature is the introduction of the Human Protein Atlas Browser within our StrataQuest software. By simply pressing the Human Protein Atlas Button compare your obtained results to publicly available data.
  • 7.0 New import formats: OME-TIFF, Olympus VSI, BigTIFF and PreciPoint.
