A comparative study of boost dose delivery techniques in breast cancer radiotherapy optimising efficacy and minimising toxicity.

The present study aims to compare three techniques for delivering a boost absorbed dose: conventional reduced tangential (3D), volumetric modulated arc therapy (VMAT) and fields forward-planned technique boost (3DF). The study included 15 postoperative breast cancer patients who received a boost absorbed dose following breast-conserving surgery. The conformity index and homogeneity index were used to evaluate treatment outcomes, along with the average absorbed dose received by organs at risk (OAR).

Using PRIMO to determine the initial beam parameters of Elekta Synergy linac for electron beam energies of 6, 9, 12, and 15 MeV.

Background: The purpose of this research was to establish the primary electron beam characteristics for an Elekta Synergy linear accelerator. In this task, we take advantage of the PRIMO Monte Carlo software, where the model developed contains the majority of the component materials of the Linac.

Materials And Methods: For all energies, the Elekta Linac electron mode and 14 × 14 cm applicator were chosen.

Sino-nasal low-grade chondrosarcoma revealed by isolated bilateral loss of sight: an unprecedented presentation of a rare tumour.

Chondrosarcomas are malignant cartilage-forming tumors representing less than 0.1% of all head and neck malignancies, and nasal cavity is an exceptional location among them. Clinical presentation could be consisting of either rhinological signs or asymptomatic endonasal mass.

Monte Carlo evaluation of particle interactions within the patient-dependent part of Elekta 6 MV photon beam applying IAEA phase space data.

Background: This work aims to provide a simulated method to be used by designers of medical accelerators and in clinical centers to manage and minimize particles' interaction in the patient-dependent part of a 6 MV X-Ray Beam generated by the Elekta linear accelerator system, based on the latest GATE software version 9.0 Monte Carlo simulation, IAEA phase space data, and the last version of "Slurm" computing cluster.

Materials And Methods: The experimental results are obtained using the Elekta 6 MV accelerator.

Dosimetric study of Hounsfield number correction effect in areas influenced by contrast product in lungs case.

Background: The aim of the study was dosimetric effect quantification of exclusive computed tomography (CT) use with an intravenous (IV) contrast agent (CA ), on dose distribution of 3D-CRT treatment plans for lung cancer. Furthermore, dosimetric advantage investigation of manually contrast-enhanced region overriding, especially the heart.

Materials And Methods: Ten patients with lung cancer were considered.
