ITK is an open-source software toolkit for performing registration and segmentation. Segmentation is the process of identifying and classifying data found in a digitally sampled representation. Typically the sampled representation is an image acquired from such medical instrumentation as CT or MRI scanners. Registration is the task of aligning or developing correspondences between data. For example, in the medical environment, a CT scan may be aligned with a MRI scan in order to combine the information contained in both.
The Medical Imaging Interaction Toolkit (MITK) is a free open-source software system for development of interactive medical image processing software. MITK combines the Insight Toolkit (ITK) and the Visualization Toolkit (VTK) with an application framework. As a toolkit, MITK offers those features that are relevant for the development of interactive medical imaging software covered neither by ITK nor VTK.
Core features of the MITK platform:
PixelMed Java DICOM Toolkit is a stand-alone DICOM toolkit that implements code for reading and creating DICOM data, DICOM network and file support, a database of DICOM objects, support for display of directories, images, reports and spectra, and DICOM object validation.
The toolkit is a completely new implementation, which does not depend on any other DICOM tools, commercial or free. It does make use of other freely available pure Java tools for compression and XML and database support.
The Image-Guided Surgery Toolkit is a high-level, component-based framework which provides a common functionality for image-guided surgery applications. The framework is a set of high-level components integrated with low-level open source software libraries and application programming interfaces (API) from hardware vendors.
Grassroots DICOM (GDCM) is an implementation of the DICOM standard designed to be open source so that researchers may access clinical data directly. GDCM includes a file format definition and a network communications protocol, both of which should be extended to provide a full set of tools for a researcher or small medical imaging vendor to interface with an existing medical database.
The goal of OpenIGTLink is to provide a standardized mechanism to connect software/hardware through the network for image-guided therapy (IGT) applications. The features of OpenIGTLink include:
The Arden Syntax as a standardized language to represent medical knowledge can be used to express medical knowledge.
Arden2ByteCode is a open source compiler for the Arden Syntax. Arden2ByteCode runs on Java Virtual Machines (JVM) and translates Arden Syntax directly to Java bytecode (JBC)
executable on JVMs. It also serves as runtime environment for execution of the compiled bytecode.
The PUMA Repository (Pascal units for medical applications) is a collection of reusable source code for bioinformatics. It is compatible with Lazarus and Free Pascal, parts of the source code can also be used with Delphi and winsoft Pocket Studio.
Components of the PUMA repository include a unit converter for transforming instrumentation readouts consisting of a numerical value and a measurement unit, and an HL7 engine for reading, parsing, compiling and writing HL7 messages.
CyberUnits is a cross-platform class library for rapid programming of high-performance computer simulations in life sciences. It supports modelling for biomedical cybernetics and systems biology with Object Pascal, S and Matlab.
