Dosimetric comparison of different treatment modalities for stereotactic radiotherapy
BACKGROUND The modalities for performing stereotactic radiotherapy (SRT) on the brain include the cone-based linear accelerator (linac), the flattening filter-free (FFF) volumetric modulated arc therapy (VMAT) linac, and tomotherapy. In this study, the cone-based linac, FFF-VMAT linac, and tomotherapy modalities were evaluated by measuring the differences in doses delivered during brain SRT and...
متن کاملComparison of four techniques for spine stereotactic body radiotherapy: Dosimetric and efficiency analysis
PURPOSE The aim of this study is to compare the dosimetric differences between four techniques for spine stereotactic body radiotherapy (SBRT): CyberKnife (CK), volumetric modulated arc therapy (VMAT), and helical tomotherapy (HT) with dynamic jaws (HT-D) and fixed jaws (HT-F). MATERIALS/METHODS Data from 10 patients were utilized. All patients were planned for 24 Gy in two fractions, with th...
متن کاملDosimetric Comparison of Two Craniospinal Radiotherapy Techniques for Treatment Optimization
Introduction: Orthogonal radial fields are those in which the central axes are perpendicular to each other. An example of these orthogonal fields is the set of craniospinal orthogonal fields that are used for radiotherapy of medulloblastoma. Craniospinal radial fields consist of two parallel-opposed fields for brain exposure and one or two posterior spinal fields for spinal cord exposure. The m...
متن کاملStereotactic Radiotherapy for Liver Metastases
Liver metastases are common in oncologic patients, causing substantial morbidity and mortality. Systemic therapy is now standard palliative treatment for most patients with liver metastases, often providing transient responses and increased overall survival. In selected oligometastatic patients, local treatment can lead to long disease-free intervals and even permanent disease control. Although...
متن کاملDosimetric and motion analysis of margin-intensive therapy by stereotactic ablative radiotherapy for resectable pancreatic cancer
BACKGROUND The retroperitoneal margin is a common site of positive surgical margins in patients with resectable pancreatic cancer. Preoperative margin-intensive therapy (MIT) involves delivery of a single high dose of ablative radiotherapy (30 Gy) focused on this surgically inaccessible margin, utilizing stereotactic techniques in an effort to reduce local failure following surgery. In this stu...
