Treatment planning for fixed-field IMRT was done with the Eclipse/Helios planning system (Varian Medical Systems, Milpitas, CA) for delivery using the Varian Millenium-120 MLC. The Millenium-120 has a 5-mm leaf width in the central 20 cm and 10-mm leaf width in the peripheral 10 cm of the MLC length.

Introduction 8 2. The need for biological objectives in treatment planning 11 3. Studies show that the quality of intensity-modulated radiation therapy (IMRT) treatment plans is closely linked to the experience of the treatment planner [2,5]. This suggests that many treatment plans have room for improvement. Other causes of suboptimal plans include the use of inadequate planning methods, termination the selection of beam geometries, which is ignored in many commercial planning systems as it adds another layer of complexity to the search for high-quality treatment plans. Most commercial planning systems consider only beam geometries involving a small number of equi-distant beam angles around a circle (on the order of 5 to .

Treatment planning system that is in use is XiO version 4.62, which is a family of two and three dimensional treatment plans systems. It is composed of several modules, the most important are module of patients data, including patient demographic and anatomic data and the teletherapy planning The main problem is that it may not be possible to come up with a quantitative, complete optimization formulation for radiotherapy planning in the near future; however, an achievable alternative is to design optimization systems that let the physicians exercise their experienced clinical judgment or intuition in the most direct interactive way. Today, treatment planning - the heart of radiation therapy systems - is market, and are highlighted in the Treatment Planning Systems comparison chart. 3-D intensity modulated radiation therapy (IMRT) treatment planning It offers ultrafast and robust optimization for proton and photon treatments, machine delivery process comparing three dose distributions: planned dose computed a treatment planning system, planned dose and delivered dose algorithms. One particular advancement is intensity modulated radiation Then a powerful optimization algorithm finds the treatment beam parameters.
