Assessment of Olfactory Threshold in Patients Undergoing Radiotherapy for Head and Neck Malignancies
Introduction: Radiotherapy is a common treatment modality for patients with head and neck malignancies. As the nose lies within the field of radiotherapy of the head and neck, the olfactory fibers and olfactory receptors may be affected by radiation. The aim of this study was to evaluate changes in olfactory threshold in patients with head and neck malignancies who have received radiation to th...

Doses in organs at risk during head and neck radiotherapy using IMRT and 3D-CRT
BACKGROUND.: Treatment planning for head and neck (H&N) cancer is complex due to the number of organs at risk (OAR) located near the planning treatment volume (PTV). Distant OAR must also be taken into consideration. Intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) are both common H&N treatment techniques with very different planning approaches. Alth...
متن کاملApplying machine learning to automated segmentation of head and neck tumour volumes and organs at risk on radiotherapy
Radiotherapy is one of the main ways head and neck cancers are treated; radiation is used to kill cancerous cells and prevent their recurrence. Complex treatment planning is required to ensure that enough radiation is given to the tumour, and little to other sensitive structures (known as organs at risk) such as the eyes and nerves which might otherwise be damaged. This is especially difficult ...
متن کاملComparison of Absorbed Dose in Thyroid and Lens as Organs at Risk Between in vivo Dosimetry and 3-D Treatment Planning Calculation in Head and Neck Radiotherapy by Linac Beam
Introduction: Critical organs and structures may receive significant amounts of irradiation even if they are not the target of radiotherapy or located outside the treatment field. Although the sensitive thyroid gland and lens are not directly the targets of treatment, they can be affected by irradiation during the treatment of tumours in head and neck region. The purpose of thi...
