Viewer and Viewer+

Fast navigation innovated

The Viewers are a central part of Visiopharms end-to-end digital pathology solutions. Validated for in vitro diagnostic use (CE IVD) in Europe in combination with the CE IVD APPs from Visiopharm (ref. 1). All other applications are for Research Use Only.

The Visiopharm Viewer handles the widest support of whole slide formats and supports Field-Of-View (FOV) image types. Tailored for both diagnostic and research environment the Viewer supports brightfield, fluorescence as well as multispectral image modalities, which are presented with comprehensive possibilities for enhancements and adjustments

Advanced viewing with Viewer+
For advanced image analysis and APPs the Viewer+ module allows alignment and co-registration in the TissuealignTM module and enables easy, robust and automated tumor and stroma separation with VirtualDoubleStainingTM. The Viewer+ also opens up for multiplexing
between various types of staining methods with the Visiopharm VirtualMultiplexingTM feature.

Diagnostic Use
With Viewer, pathologists have all the tools necessary for on-screen rapid review and diagnosis. For automated image analysis Visiopharm offers a range of APPs and expansion modules, which can free up pathologist time and improve speed of throughput.

Research Use
For research use the ability to tailor all aspects of the image display and Viewer components assists researchers in their design and appliance of new algorithms and APPs. Special tools enable direct measurement and display of distance, curve length, angle, radius, diameter, and
area. Only one mouse click away in the very intuitive and easy-to-use wheel menu.

Wheel Menu
All annotations and image analysis findings are easily shown, hidden and transparency adjusted via the intuitive wheel menu, which opens up a rich set of tools for outlining of regions, measuring, annotations and support of quantitative image analysis.

Fluorescence Images
Viewing fluorescence images requires correct identification of color information, which is handled in the Viewer. Wavelengths and names of channels are read from image files and can be modified if necessary. The Viewer supports all color formats ranging from standard brightfield to high sensitivity multispectral images including fluorescence.

Multispectral Images
There is no limit to the number of color bands used in the Viewer. Most bright-field images are composed of three bands (Red, Green, Blue), but the Viewer can handle any number of bands, including combination of bright-field images and fluorescent channels. With the control of colors and stretch on each individual band the viewing possibilities are endless.

The Visiopharm APPs for Breast Cancer Ki-67, ER and PR are validated for in vitro diagnostic use (CE IVD) in Europe utilizing the Visiopharm Viewer (ref. 1). The Viewer can be used for “off the screen” diagnosing by any trained pathologist. For all other applications, the Viewer can be used for Research Use Only.
