Adenoid cystic carcinoma (ACC) is a rare malignant tumour arising from salivary glands. ACC of the head and neck shows long natural course, high recurrence rates, late metastasis tendency for perineural invasion. The authors present woman with at base tongue good response to radiotherapy.
Background: Performing audits play an important role in quality assurance program radiation oncology. Among different algorithms, TiGRT is one of the common application software for dose calculation. This study aimed to clinical implications algorithm measure and compared calculated delivered patients a variety cases, with without presence inhomogeneities beam modifiers. Materials Methods: Nonhomogeneous phantom as verification phantom, Farmer ionization chambers, PC-electrometer (Sun...
Abstract Background: Using three-dimensional conformal radiation treatment (3D-CRT) and helical tomotherapy (HT), this study examines contrasts the dosage received by mandible, maxilla, teeth. Methods: Sixteen patients with head-and-neck cancer (H NC) were subject of planning at Seyyed Al-Shohada Hospital in Isfahan, Iran. This examined target coverage quality, exposure healthy tissue, delivery effectiveness. Results: In terms a number measures, including D 2% , 50% mean V 95% conformity...
The goal of this study was to assess the impact deep local hyperthermia on oxygen (O
This study aimed to evaluate the overall accuracy of beam commissioning criteria targeted image-guided radiation therapy (TiGRT) treatment planning system (TPS) based on American Association Physicists in Medicine (AAPM) Task Group Report 119 (TG-119).The work was performed using 6 MV energy LINAC with a variable dose rate 200 MU/min which equipped high-quality external TiGRT dynamic multileaf collimator model H. The AAPM TG-119 intensity-modulated (IMRT) tests are composed two preliminary...
This study aimed to evaluate the overall accuracy of beam commissioning criteria targeted image‑guided radiation therapy (TiGRT) treatment planning system (TPS) based on American Association Physicists in Medicine (AAPM) Task Group Report 119 (TG‑119). The work was performed using 6 MV energy LINAC with a variable dose rate 200 MU/min which equipped high‑quality external TiGRT dynamic multileaf collimator model H.

Chemoradiotherapy with controlled-release nanocarriers such as sono-sensitive nanodroplets (NDs) can enhance the anticancer activity of chemotherapy medicines and reduces normal tissue side effects. In this study, folic acid-functionalized methotrexate(MTX)-loaded perfluorohexane NDs, each an alginate shell (FA-MTX/PFH@alginate NDs), were synthesized, characterized, their potential for smart ultrasound-controlled drug delivery was investigated in vitro vivo . Cancer cell (4T1) viabilities...
Background: Multi-leaf collimator (MLC) is one of the efficient and cost-effective methods for protecting sensitive tissues around target. This study aimed to evaluate protective effect MLC on protection organs in patients with left breast cancer. Materials Methods: was performed computed tomography (CT) scans 45 Two treatment plans were completed each patient. Only heart lung considered at risk first plan, second anterior descending artery (LAD) also organ risk. It covered as much possible...
Two of the main sources public exposure from natural radioactivity are radium and radon, their short-lived decay products. The aim this study is to determine concentration these radionuclides in mineral water resources one highest-altitude regions (Zagros Mountains) Chaharmahal Bakhtiari Province, south-west Iran, namely Dimeh Springs. Eighty drinking springwater samples were taken Springs (ten for each spring) radium-226 radon-222 concentrations using emanation method a liquid scintillation...
Radiotherapy (RT) may increase the dose of heart structure like left anterior descending coronary artery (LAD). The purpose this paper was to evaluate impact various multileaf collimators (MLCs) in shielding organ at risks (OARs), especially LAD, patients with breast cancer.Forty-five cancer were selected. treatment plans created applying three techniques for all patients. In first plan (uncovered LAD), made without considering LAD as OARs. two other plans, MLCs different leaf widths (6.8 mm...
