Design and Implementation of Head and Neck Perspex Phantom for Intensity Modulated Radiation Therapy
نویسندگان
چکیده
The aims of this study are to design, construct and evaluate the applicability of a head and neck Perspex phantom for dosimetric verification of intensity modulated radiation therapy (IMRT). Thermoluminescent dosimeters (TLDs) was used in this study. Consistency of the fabricated phantom readings was checked by multiple IMRT irradiations. The inter-fraction standard deviation among all TLDs’ measurement was 3.7%, and the averages of all repetitive measurements at OAR and PTV were comparable with TPS with a percentage variation of 4.8% (SD 8.1) and P value > 0.05 (95% CI). These findings suggest the consistency and the reproducibility of the phantom and its applicability for IMRT treatment verification.

The head and neck is a challenging anatomic site for intensity-modulated radiation therapy (IMRT), requiring thorough testing of planning and treatment delivery systems. Ideally, the phantoms used should be anatomically realistic, have radiologic properties identical to those of the tissues concerned, and allow for the use of a variety of devices to verify dose and dose distribution in any targ...

Introduction: Globally, intensity-modulated radiation therapy (IMRT) is considered as highly precise and accurate method of radiotherapy planning. This technique amplifies spatial dose distribution conformity by modulating the intensity of radiation beams in each sub-volume. Additionally, it can reduces the dose to surrounding critical organs and deliver the planned dose to targets with the nom...

Background: Commissioning tests are recommended before implementing Intensity Modulated Radiation Therapy. This study evaluated five different plans of IMRT mocks for different modulation indices. Materials and Methods: IMRT tests were done in slab phantom for both 6MV and 15 MV photon energies using a 2D array ion chamber dosimeter. Results: The acceptance criteria were based on 3% /3mm. All t...

Abstract Background: Adjacent treatment fields are commonly used in external beam radiation therapy, such as mantle and inverted-Y fields for the treatment of Hodgkin’s disease and craniospinal fields used in the treatment of medulloblastoma and head and neck tumors when the lateral neck fields are placed adjacent to the anterior supraclavicular field. In each of these situations, there is a p...
