The arivis Browser is our basis for the capturing, assembly, visualization and analysis of large, multi-dimensional image data. The arivis Browser cooperates with any image capturing device - from fluorescence microscope in Life Science to aerial cameras for cartography.

The arivis Browser is capable of handling image data of any size containing up to four dimensions. Here the logical dimensions can be deliberately matched with real dimensions. Of course, it is possible to except single dimensions.
Thus, you can for instance visualize with one four dimensional stack of data the following:

• Three-dimensional image stack with additional spectral dimension, e.g. from confocal laserscan microscopy
• Temporal succession of two-dimensional images, e.g. from the observation of living cells
• Two-dimensional image data with multiple focus, e.g. for analyzing biological objects
• Overlap of several two-dimensional data sources with additional spectral information, e.g. aerial fotography or satellite pictures

The image volumes can be composed of any amount of single images. For that, the acquisition module of the arivis Browser combines conventional image capturing devices (e.g. microscopes) with positioning units (e.g. motorized compound tables). It ensures the dimensional classification of the single images. To obtain the single images, we use the capturing software of the device, that the arivis Browser adresses via integrated device drivers.

Specific alignment-modules assemble a stack from the single images and the dimensional information and eliminate artifacts of images, that occured through positioning.

The assembled stack can be browsed in real time, independently of its size.

The arivis Browser is a modular, extensible system. Extensions are possible into various directions, e.g.

• Integration of devices
• Assembly and alignment
• Import of any formats
• Visualization of data
• Modification of data
• Analysis of data
• Export into any formats

There exist modules for the arivis Browser that provide all basic functions of a system for data visualization, e.g.:

• Navigation within the data stack
• Parametrical changes (contrast, brightness, gamma...)
• Look-up-tables for values of intensity (for any false color renderings)
• Projections on the data stack
• Filter and Modifications of data
• Data annotation
• 3D-Visualization

The arivis Browser provides general instruments for quantitative analysis of image data:

• Measuring of length
• Measuring of perimeter and area
• Measuring of volume
• Segmentation

In addition, there exists a collection of highly specialized modules for analysis and evaluation, that are designed for one specific application.
