Delineation of organs at risk involved in swallowing for radiotherapy treatment planning.
BACKGROUND AND PURPOSE Radiotherapy, alone or combined with chemotherapy, is a treatment modality used frequently in head and neck cancer. In order to report, compare and interpret the sequelae of radiation treatment adequately, it is important to delineate organs at risk (OARs) according to well-defined and uniform guidelines. The aim of this paper was to present our institutional Computed Tom...
متن کاملInteractive contour delineation of organs at risk in radiotherapy: Clinical evaluation on NSCLC patients.
PURPOSE Accurate delineation of organs at risk (OARs) on computed tomography (CT) image is required for radiation treatment planning (RTP). Manual delineation of OARs being time consuming and prone to high interobserver variability, many (semi-) automatic methods have been proposed. However, most of them are specific to a particular OAR. Here, an interactive computer-assisted system able to seg...
متن کاملCompare the organs at risk in breast-conserving three- dimensional conformal radiotherapy (3D-CRT) based on patient\'s breast size
Introduction: Breast cancer is the most common cancer among women. Radiotherapy plays an important role in the treatment of breast cancer and essential part of the standard treatment after breast-conserving surgery, routinely done to eliminate the microscopic residual cancer. The heart and lungs are one of the most important organs at risk of breast cancer radiotherapy that th...

متن کامل3D Variation in delineation of head and neck organs at risk
BACKGROUND Consistent delineation of patient anatomy becomes increasingly important with the growing use of highly conformal and adaptive radiotherapy techniques. This study investigates the magnitude and 3D localization of interobserver variability of organs at risk (OARs) in the head and neck area with application of delineation guidelines, to establish measures to reduce current redundant va...
