Different Radiotherapy Methods: A Review
Cancer is one of the principal causes of mortality in the modern world. There are different treatment methods available for cancer such as surgery, chemotherapy, radiotherapy, and hormone therapy. About 40% of all cancer patients receive radiotherapy during their illness for treatment or for local control or symptomatic palliation. In clinical radiation oncology, the final aim is to attain unco...
متن کاملEvaluation of Deformable Image Registration (DIR) Methods for Dose Accumulation in Nasopharyngeal Cancer Patients during Radiotherapy
Introduction Deformable image registration (DIR) is used to modify structures according to anatomical changes for observing the dosimetric effect. In this study, megavoltage computed tomography (MVCT) images were used to generate cumulative doses for nasopharyngeal cancer (NPC) patients by various DIR methods. The performance of the multiple DIR methods was analysed, and the impact of dose accu...
متن کاملEvaluation of Deformable Image Registration Methods for Dose Monitoring in Head and Neck Radiotherapy
In the context of head and neck cancer (HNC) adaptive radiation therapy (ART), the two purposes of the study were to compare the performance of multiple deformable image registration (DIR) methods and to quantify their impact for dose accumulation, in healthy structures. Fifteen HNC patients had a planning computed tomography (CT0) and weekly CTs during the 7 weeks of intensity-modulated radiat...
متن کاملGeodesic Registration for Cervical Cancer Radiotherapy
Uterus, bladder and rectum are the maximally exposed organs during cervical cancer radiotherapy and are at high risk of radiation exposure. Estimation of dose accumulation in these organs across multiple fractions of external beam radiotherapy (EBRT) and brachytherapy (BT) is extremely challenging due to structural mis-correspondences and complex anatomical deformations between the EBRT and BT ...
