title: A free program for calculating EUD-based NTCP and TCP in external beam radiotherapy.
abstract: OBJECTIVE
  Provide a simple research tool that may be used to calculate the NCTP or TCP of a particular treatment plan. Illustrate the implementation of the EUD-based NTCP and TCP models as a research tool.
  
  
  METHODS
  A high-level computing language was chosen to implement Niemierko's EUD-based NTCP and TCP mathematical models. The necessary treatment planning software requirements were clearly defined.
  
  
  RESULTS
  The computer code is presented and explained. Six simple examples were created to quickly troubleshoot the reader's code implementation. A table of model parameters based on the Emami data was generated.
