Thyroid dose and dose reduction method from CT scan of head and neck
Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...
متن کاملA Review on the Efficacy of Chemotherapy in Locally Advanced Head and Neck Cancers
Background and Aims: Chemotherapy is utilized as a part of combined-modality programs to achieve organ preservation and improve survival in patients with locally advanced head and neck cancer. Combinedmodality protocols can be used in three forms: a) neoadjuvant induction chemotherapy before definitive surgery or radiotherapy; b) concomitant chemoradiotherapy; and c) sequential therapy consisti...
متن کاملDose Distribution Analysis of Rapid Arc and Intensity Modulated Radiotherapy Plan in Head and Neck Cancer
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...

متن کاملAssessment of secondary neutron dose due to dental restorations in head and neck radiation therapy
Introduction: One of scientific concern is increasing of unwanted neutron dose to the patient, in head and neck radiation therapy due to the presence of some isotopes in dental restorations and head of medical linac. The aim of this study is to measure the equivalent dose of thermal and fast neutron due to head of Siemens Primus Linac and a healthy tooth, Amalgam, Ni-Cr alloy a...
