    OpenPatientOS

    OpenPatientOS

    OpenPatientOS is an information system for managing patient records

    It can support a small clinic or hospital in managing patient personal, medical, and billing records through an easy to use Swing user interface. How to install: i. Simply import the database dump from the database folder to create the necessary tables for the system to run. You can use either phpMyAdmin for localhost; Microsoft SQL Server; or simply Query Browser for MySQL. Other database environments have not been tested hence I don't guarantee their adaptability. ii. Run and Build the system in NetBeans IDE 7.0. Other IDEs have not been tested for this system. A more stable and installable version will be released soon. iii. Please rate the system and leave comments or reviews. iv. If you need any further clarification, post a question/query/doubt in the Wiki and I will reply ASAP. NB: Please use the "External Link" menus above to support this project in one way or another. PM me for other means. Any kind of support will be very much appreciated. Thanks a bunch.

    SMILI

    SMILI

    Scientific Visualisation Made Easy

    The Simple Medical Imaging Library Interface (SMILI), pronounced 'smilie', is an open-source, light-weight and easy-to-use medical imaging viewer and library for all major operating systems. The main sMILX application features for viewing n-D images, vector images, DICOMs, anonymizing, shape analysis and models/surfaces with easy drag and drop functions. It also features a number of standard processing algorithms for smoothing, thresholding, masking etc. images and models, both with graphical user interfaces and/or via the command-line. See our YouTube channel for tutorial videos via the homepage. The applications are all built out of a uniform user-interface framework that provides a very high level (Qt) interface to powerful image processing and scientific visualisation algorithms from the Insight Toolkit (ITK) and Visualisation Toolkit (VTK). The framework allows one to build stand-alone medical imaging applications quickly and easily.
