Intensity－modulated radiotherapy(IMRT) is an advanced conformal therapy and it can increase the ratio of gains of radiotherapy and improve the local control of the tumor． This paper introduces a planning system for intensity－modulated radiotherapy， which applies an accurate method to calculate the dose of pen beam and inverse planning to determine the treatment planning
