ImpactView - fast and versatile CT volume slicing


ImpactViewImpactView / ImpactView Pro is a CT volumetric data viewing software with a great range of functions. It supports the DICOM image format, allows for multi-planar reformatting (MPR) as well as threshold-based surface rendering and allows for data analysis and evaluation.

Three navigation modes (slicing, panning, zooming) and an intuitive windowing mode as well as a large range of tools for ROI (region of interest) analysis and distance measurement render ImpactView an easy to use and powerful volume viewing and analysis software. The 64 bit support for Windows operating systems, included by default, allows the viewing of very large volume data sets. The only restriction is posed by the available free memory of the computer system used. ImpactView is also available with an enhanced feature set called ImpactView Pro.

Features of ImpactView

• Sliced views of volume data (transversal, coronal, sagittal)
• Advanced two-dimensional 3 plane multi-planar viewing
• Double-sloped reformatting
• Navigation by slicing, panning, zooming, windowing
• Supports "sliding thin slabs" (e.g. mean, maximum, minimum)
• Threshold-base shaded surface rendering
• ROI analysis of rectangular, circular or free-shaped selections
• Tools for distance and angle measurement in volumetric data sets
• Supports DICOM image format
• Supports very large data sets, provided the available system RAM suffices

Additional features of ImpactView Pro

• Supports import and export of 3d meshes in STL format
• Supports TomoScope© raw data formats
• Supports the proprietary MIF/MIFX image formats


• Comfortable and modern graphical user interface

ImpactView is a fast and comfortable viewing and analysing software for reconstructed volume data from computed tomography in the DICOM format.


Apart from the classic slice view, there are also an MPR view and double-oblique reformatting available for viewing and analysis. Beyond that, it is possible to dynamically take the mean of several slices or to combine them through MIP projection. Miniature views or threshold based surface renderings allow a better overview.


Data analysis is supported by easy-to-use tools, like various ROIs for the calculation of mean value, standard deviation and extremes, as well as distance and angle measurement.
