Welcome to the 2nd Messenger Systems Wiki! We're interested in biomedical and scientific visualization, among other things.

PheonixRT

PheonixRT is a radiotherapy inverse planning algorithm based on an information-theoretical optimization technique. A 2-dimensional prototype has been produced, initial results indicate that it can produces quality plans with a modest number of optimization iterations. A 3-dimensional prototype is also in the works, based on the ITK library.

Features include:

• Beamlet weight optimization
• Prescription specified as a target DVH (no partial volume points)
• Each prescription term has an adjustable weight

theWheel

theWheel is a tool for knowledge management and knowledge visualization. It works with knowledge represented as interconnected pieces of information, known as graph-based models. This is the knowledge representation approach followed by the Semantic Web, where knowledge is encoded as a graph consisting of nodes (representing resources), connected by annotated links (representing relationships among the resources).

Knowledge bases that can be represented this way include:

• A reaction pathway map for a signal transduction network
• A neural connectivity map
• A set of cross-referenced scientific papers
• A music collection
• A family tree

WarpTPS

WarpTPS is a simple implementation of thin-plate spline deformable registration. The application allows entry of an arbitrary number of landmarks positioned on both images. It then deforms the target image so that the landmarks match their position on the source image.
