Outline of Final Research Achievements	As a fundamental tool for developing a new method to solve inverse problem in intensity modulated radiation therapy, we developed an in-house treatment planning system based on a Monte-Carlo algorithm, as well as pencil beam convolution and superposition/convolution dose calculation algorithms. We also developed a in-house software to manipulate and analyze DICOM-RT files and a simple method to determine the X-ray spectrum from the treatment head of a radiation therapy apparatus.
