Radiotherapy is a treatment of carcinogenic tumors using ionising radiation and the improvement radiotherapy techniques has been conducted to protection healthy tissues. Recent implementations have employed static fields with small dimensions. The interests for this work were fields, used in modern such as Stereotactic Radiation Therapy (SRS) Intensity Modulated (IMRT).

Multileaf collimators (MLCs) are the prevailing tool for the realization of radiation fields in intensity modulated radiation therapy (IMRT). One step in the treatment planning is to determine a set of leaf positions realizing a certain intensity modulated radiation field. In this paper we suggest two extensions in the use of the MLC that lead to considerable savings in terms of monitor units, ...

BACKGROUND AND PURPOSE We verified the propriety of our systematic error reduction strategy by means of a computer simulation based on our data of position error with a prone fixation device for prostate IMRT. MATERIALS AND METHODS Computer simulations of the off-line correction method for systematic setup errors based on the portal imaging taken on the first several days of the treatment ses...

Introduction Intensity Modulated Radiation Therapy (IMRT) has made a significant progress in radiation therapy centers in recent years. In this method, each radiation beam is divided into many subfields that create a field with a modulated intensity. Considering the complexity of this method, the quality control for IMRT is a topic of interest for researchers. This article is about the various ...

3 ABSTRACT Biological treatment optimization aim at improving radiation therapy by accounting for the radiobiological tumour and normal tissues response properties when optimizing the dose delivery. Generally traditional methods, using only dosimetrical measures, disregard the non-linear radiation response of different tumours and normal tissues. The accumulated knowledge on tissue response to ...

Radiation therapy of the primary tumor can be a stage treatment patients with initial IV breast cancer, being delievered out not only in purpose decreasing symptom’s severity, but an increase progression-free survival. Modern technologies radiation therapy, including intensity-modulated radiotherapy and deep inspiration under control breathing (Respiratory Gating), significantly reduce dose to ...
