About PlanUNC


PLanUNC (PLUNC) is a portable, adaptable, and extensible set of software tools for radiotherapy treatment planning (RTP) that has been under active development in the Department of Radiation Oncology at the University of North Carolina (UNC) for approximately 20 years. In 1992, development work branched into separate paths at UNC (PLanUNC) and Sherouse Systems, Inc. (GRATISTM). The current UNC tools encompass the full range of RTP functions including image importing and processing, virtual simulation, dose calculation, plan evaluation, and planning for intensity modulated radiotherapy. PLanUNC source code and related software are licensed without fee to qualified facilities to support research involving new methods for planning and delivering radiation therapy, and to support RTP training for dosimetrists, physicists, radiation therapists, and radiation oncology residents. Research milestones of the development and application of PLanUNC can be found on the PlanUNC History Page.



PlanUNC source code is written in a modular fashion using a combination of C and C++. The code has been compiled on versions of Linux, UNIX, Microsoft Windows, and Apple Macintosh OS. The user interface is based on a freely available, cross-platform widget library called FLTK. PlanUNC has a flexible multithreaded environment that can make use of multiple processors within a single computer as well as distributed processing for dose computation across multiple computers. Programmer documentation has been developed to assist researchers in modifying and extending PLanUNC source code.



Institutions, departments, and other facilities engaged in research and education involving radiation therapy can apply to obtain a license to use PLanUNC source code. Individuals who choose to register may obtain a copy of the user guide and a compiled demo version that runs under Windows.
