Dose distribution of protons and flux of secondary particles in breast proton therapy.
Introduction: Proton therapy is newer therapeutic method for early stage breast cancer. Proton beams release most of their energy in the Bragg peak and then will be a rapid decline in their end. When protons interact with matter, produce secondary particles like neutrons and gammas, and these unwanted radiation has no beneficial effect and also is believed to increase the risk ...
متن کاملMonte Carlo calculations of dose distribution for the treatment of gastric cancer with proton therapy
Proton therapy is a common form of external radiation therapy based on the manipulation of Bragg peak of this beam, it can treat the tumor by delivering high levels of doses to it, while protecting surrounding healthy tissues against radiation. In this work, the dose distribution of proton and secondary particles such as neutrons, photons, electrons and positrons in gastric cancer proton therap...
متن کاملComputerized Addenbrooke’s Cognitive Examination for Neurocognitive Monitoring of Children with Benign and Malignant Brain Cerebellar Tumor
Background: Brain tumors in the cerebellum site, especially in the cranial nuclei, are most commonly associated with cognitive impairment in children, but the differences in dimensions of cognitive impairments in pediatric benign and malignant tumors are rarely studied. Meanwhile, cognitive impairments in this area are required to be widely studied. This study aimed at using Computerized Addenb...
متن کاملASSESSMENT OF TUMOR MARKERS IN BENIGN, DYSPLASTIC AND MALIGNANT ORAL MUCOSAL LESIONS
Immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. Accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (HSP), fibroblast growth factors (FGF) and transferrin receptors (TF-R) in 22 samples ...
متن کاملA new method for ideal dose distribution of two adjacent fields for external beam radiation therapy
Abstract Background: Adjacent treatment fields are commonly used in external beam radiation therapy, such as mantle and inverted-Y fields for the treatment of Hodgkin’s disease and craniospinal fields used in the treatment of medulloblastoma and head and neck tumors when the lateral neck fields are placed adjacent to the anterior supraclavicular field. In each of these situations, there is a p...
