A Neonatal Bimodal MR-CT Head Template
Neonatal MR templates are appropriate for brain structural analysis and spatial normalization. However, they do not provide the essential accurate details of cranial bones and fontanels-sutures. Distinctly, CT images provide the best contrast for bone definition and fontanels-sutures. In this paper, we present, for the first time, an approach to create a fully registered bimodal MR-CT head temp...
متن کاملMR-guided multi-atlas based synthetic CT for MR-only radiotherapy of head and neck cancer patients
S71 ______________________________________________________________________________________________________ provided by dual-energy CT (DECT) compared to singleenergy CT (SECT) can be clinically used to reduce CT-based range uncertainties and to analyze intraand interpatient tissue variations. First, a DECT scan protocol was optimized and clinically introduced. Second, in a first analysis patien...
متن کاملMR imaging-guided interstitial photodynamic laser therapy for advanced head and neck tumors.
Photodynamic therapy (PDT) is a site-specific tumor treatment involving the administration of a photosensitizer activated by the local application of light. In interstitial PDT (IPDT), multiple laser fibers are inserted into the depth of the tumor. Image guidance is essential for accurate, safe, and uniform light delivery. We report a novel technique of IPDT for advanced head and neck tumors in...
متن کاملMR-guided adaptive focusing of therapeutic ultrasound beams in the human head.
PURPOSE This study aims to demonstrate, using human cadavers the feasibility of energy-based adaptive focusing of ultrasonic waves using magnetic resonance acoustic radiation force imaging (MR-ARFI) in the framework of non-invasive transcranial high intensity focused ultrasound (HIFU) therapy. METHODS Energy-based adaptive focusing techniques were recently proposed in order to achieve aberrat...
متن کاملMR-guided RF Ablation
Background: Cardiac arrhythmias are common, affecting 3-5 % of the over 40s. Population growth and ageing will lead to a large increase in new arrhythmia cases [1]. Cardiac arrhythmias cause considerable morbidity and significant mortality as well as considerable anxiety in patients and their relatives. Early and accurate diagnosis is essential for the selection of an appropriate treatment, whi...
