VivoQuant™ is a DICOM compliant post-processing suite for image data combining fundamental viewing functionality with powerful analysis capabilities. VivoQuant (“VQ”) supports data from most imaging modalities including MR, PET, SPECT, CT, and Optical. Multiple display modes including orthogonal views, slice views, special co-registration multi-views as well as 3D MIPs and volume renderings allow users to optimally view information of interest. Built-in features allow imaging scientists to extract the information they need with minimal effort, including powerful tools for fine-tuning images and isolating, drawing and analyzing 3D regions of interest. VivoQuant’s integration with iPACS, a full image study data management platform, offers sophisticated data management, reporting and data sharing tools of VivoQuant-generated data.
Supports the visualization and analysis of both static and dynamic image data sets across multiple modalities (CT, PET, SPECT, MR, and Optical; over 32 data formats). Extensive viewing features including slice view, orthogonal views, multiple planar reconstruction (MPR), multi-dataset view, and tile view.
Image Registration and Pre-processing Tools
Multi-modal registration (automated, manual or user-provided fiducial markers). Additional features include filtering, cropping, smoothing, and re-scaling functionality.
Easy-to-use Analysis Packages
3D ROI segmentation via automatic, semi-automatic and manual tools. Supports Plugin Modules for brain and whole body atlas based segmentation and tracer-kinetic modeling. MR analysis toolkits for generating T1, T2, ADC, and fat quantification maps and performing fMRI analysis.
Data Publication Tools
Publish analysis data in tabular and graphical output. Plotting tools for time-activity and time-signal curves, contours and histograms. Image and movie generation for all viewing functions in a broad range of file formats.
Image and analysis data can be managed by the iPACS platform delivering integrated data management, reporting, and sharing capabilities.
Tracer Kinetic Modeling
Tracer Kinetic modeling is a functional imaging technique that is used to analyze the concentration of a tracer molecule in a specific target tissue. Invicro’s Compartmental Modeling tool allows users to take advantage of the 3D ROI tool for region- and voxel-level analysis across various compartmental models (specified below). Currently, the Tracer Kinetic Modeling tool empowers the user to estimate parameters in a ROI or individual voxel and provides the ability to preserve user-defined variables when switching between methods (ex. k2’ for SRTM2 and MRTM2)
