Microscopy mode provides the tools needed to efficiently view and annotate digital microscopy images.

Basic Viewer

View any medical image

Has all of the typical basic functions of a PACS viewer, such as layout, W/L, zoom, pan, measure, annotate, capture, probe, etc. A handful of advanced features are available such as MPR, 3D crosshair, stack sync, and reference lines.

Basic Viewer


PET/CT Standardized Uptake Value workflow

This workflow makes it easy to obtain normalized measurements of radiotracer uptake in tumors. The tools follow a typical PET SUV workflow, and the associated hanging protocol offers a convenient view of the PET study from different perspectives, including fusion with CT and rotational MIP.


View and annotate digital microscopy images

Microscopy mode is equipped with a set of tools for annotation and defining regions of interest that are relevant to a digital pathology workflow, improving your focus.
