PURPOSE MRI-based skull segmentation is a useful procedure for many imaging applications. This study describes a methodology for automatic segmentation of the complete skull from a single T1-weighted volume. METHODS The skull is estimated using a multi-atlas segmentation approach. Using a whole head computed tomography (CT) scan database, the skull in a new MRI volume is detected by nonrigid ...

To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

Background and purposeOsteoradionecrosis (ORN) affects the patient’s quality of life by making eating maintaining oral hygiene painful. This study aimed to analyze carbon ion radiotherapy (C-ion RT)-induced ORN mandible.Materials methodsA retrospective 199 patients with head neck tumors treated C-ion RT was performed from 2010 2019. Only 11 located in oropharynx floor mouth were analyzed. consi...

Organized by Working Group 6 “Computational Dosimetry” of the European Radiation Dosimetry (EURADOS), a group intercomparison exercises was conducted in which participants were asked to solve predefined problems computational dosimetry. The results these comparisons published series articles this virtual special issue Measurements. This paper reviews experience gained from various and highlight...

Abstract Purpose Pediatric brain tumor patients often experience significant cognitive sequelae. Resting-state functional MRI (rsfMRI) provides a measure of network organization, and we hypothesize that pediatric treated with proton therapy will demonstrate abnormal architecture related to outcome radiation dosimetry. Participants Methods were enrolled on prospective study assessment using the ...

Introduction: In radiotherapy, methods of treatment planning are becoming increasingly more complicated. This requires verification of the doses delivered to increasingly smaller and more precise regions. Radiotherapy techniques are continuously employing smaller and smaller field sizes to deliver tighter radiation doses with higher therapeutic ratios, generating interest among researchers to p...

Potential sanitary effects related to electromagnetic fields exposure raise public concerns, especially for fetuses during pregnancy. Human fetus exposure can only be assessed through simulated dosimetry studies, performed on anthropomorphic models of pregnant women. In this paper, we propose a new methodology to generate a set of detailed utero-fetal unit (UFU) 3D models during the first and t...
