Static versus dynamic intensity-modulated radiotherapy ...

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2805892/
    This study is aimed to evaluate the impact of static and dynamic intensity modulated radiotherapy (IMRT) delivery techniques planned with Eclipse TPS on the integral dose to the healthy normal tissue surrounding the tumor-bearing area and to the volume receiving doses < 5 Gy in patients with carcinoma nasopharynx treated with Simultaneous Integrated Boost IMRT (SIB-IMRT).

    Intensity Modulated Radiation Therapy (IMRT) Intensity Modulated Radiation Therapy (IMRT) is a computer-based method of planning for, and delivery of generally narrow, patient specific, spatially and often temporally modulated beams of radiation to solid tumors within a patient.

Is RapidArc more susceptible to delivery uncertainties ...

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3461049/
    Sep 11, 2012 · Purpose: Rotational IMRT has been adopted by many clinics for its promise to deliver treatments in a shorter amount of time than other conventional IMRT techniques. In this paper, the authors investigate whether RapidArc is more susceptible to delivery uncertainties than dynamic IMRT using fixed fields.Author: Gregory T. Betzel, Byong Yong Yi, Ying Niu, Cedric X. Yu

IMRT Techniques - Introduction

    http://oftankonyv.reak.bme.hu/tiki-index.php?page=IMRT+Techniques
    IMRT is the delivery of radiation to the patient via fields that have non-uniform radiation fluence. With this technique the concave PTV with surround normal tissue (prostate, head and neck) also can be irradiated. IMRT techniques IMRT can be applied in several ways. The following table summarized the different technical solutions.

    The goal of this planning study was to compare step-and-shoot intensity-modulated radiotherapy (IMRT) plans with helical dynamic IMRT plans for oropharynx patients on the basis of dose distribution.

Intensity Modulated Radiation Therapy - Medical Clinical ...

    http://www.aetna.com/cpb/medical/data/500_599/0590.html
    Collimator-based IMRT uses computers to modify the intensity of the beam across each individual field with the use of moving collimators. Conventional treatment with multi-leaf collimation (MLC) uses static positions of the collimator leaves whereas IMRT allows the dynamic motion of the various collimator leaves during each session of therapy.
