=== Definiens Tissue Studio ===

''Definiens Tissue Studio'' is a [[digital pathology]] image analysis software application based on CNT.<ref>{{cite web |url=http://www.definiens.com/technology_41_1_4.html |title=Archived copy |accessdate=2010-02-10 |deadurlurl-status=yesdead |archiveurl=https://web.archive.org/web/20100325202459/http://www.definiens.com/technology_41_1_4.html |archivedate=2010-03-25 |df= }}</ref>

The intended use of Definiens Tissue Studio is for biomarker [[translational research]] in formalin-fixed, paraffin-embedded tissue samples which have been treated with [[Immunohistochemistry|immunohistochemical]] staining assays, or [[H&E stain|hematoxylin and eosin]] (H&E).<ref>{{cite web |url=http://www.definiens.com/tissuestudio |title=Archived copy |accessdate=2010-02-10 |deadurlurl-status=yesdead |archiveurl=https://web.archive.org/web/20091004154007/http://www.definiens.com/tissuestudio/ |archivedate=2009-10-04 |df= }}</ref>

The central concept behind Definiens Tissue Studio is a user interface that facilitates [[machine learning]] from example digital histopathology images in order to derive an image analysis solution suitable for the measurement of [[biomarkers]] and/or histological features within pre-defined regions of interest on a cell-by-cell basis, and within sub-cellular compartments.<ref>{{cite web |url=http://www.definiens.com/tissuestudio |title=Archived copy |accessdate=2010-02-10 |deadurlurl-status=yesdead |archiveurl=https://web.archive.org/web/20091004154007/http://www.definiens.com/tissuestudio/ |archivedate=2009-10-04 |df= }}</ref> The derived image analysis solution is then automatically applied to subsequent digital images in order to objectively measure defined sets of multiparametric image features. These data sets are used for further understanding the underlying biological processes that drive [[cancer]] and other diseases.<ref>{{Cite web |url=http://laboratorian.advanceweb.com/Article/The-Image-Analysis-Challenge.aspx |title=Archived copy |access-date=2016-06-28 |archive-url=https://web.archive.org/web/20110707090609/http://laboratorian.advanceweb.com/Article/The-Image-Analysis-Challenge.aspx |archive-date=2011-07-07 |dead-url-status=yesdead }}</ref> Image processing and data analysis are performed either on a local desktop computer workstation, or on a server grid.<ref>{{cite web |url=http://www.definiens.com/tissuestudio |title=Archived copy |accessdate=2010-02-10 |deadurlurl-status=yesdead |archiveurl=https://web.archive.org/web/20091004154007/http://www.definiens.com/tissuestudio/ |archivedate=2009-10-04 |df= }}</ref>
