Intended Use

uWS-MR is a software solution intended to be used for viewing, manipulation, communication, and storage of medical images. It supports interpretation and evaluation of examinations within healthcare institutions. It has the following additional indications: The MR Stitching is intended to create full-format images from overlapping MR volume data sets acquired at multiple stages. The Dynamic application is intended to provide a general post-processing tool for time course studies. The Image Fusion application is intended to combine two different image series so that the displayed anatomical structures match in both series. MRS (MR Spectroscopy) is intended to evaluate the molecule constitution and spatial distribution of cell metabolism. It provides a set of tools to view, process, and analyze the complex MRS data. This application supports the analysis for both SVS (Single Voxel Spectroscopy) and CSI (Chemical Shift Imaging) data. The MAPs application is intended to provide a number of arithmetic and statistical functions for evaluating dynamic processes and images. These functions are applied to the grayscale values of medical images. The MR Breast Evaluation application provides the user a tool to calculate parameter maps from contrast-enhanced time-course images. The Brain Perfusion application is intended to allow the visualization of temporal variations in the dynamic susceptibility time series of MR datasets. MR Vessel Analysis is intended to provide a tool for viewing, manipulating, and evaluating MR vascular images. The Inner view application is intended to perform a virtual camera view through hollow structures (cavities), such as vessels. The DCE analysis is intended to view, manipulate, and evaluate dynamic contrast-enhanced MRI images. The United Neuro is intended to view, manipulate, and evaluate MR neurological images. The MR Cardiac Analysis application is intended to be used for viewing, post-processing and quantitative evaluation of cardiac magnetic resonance data.
