Endoscopy-MR Image Fusion for Image Guided Procedures
Minimally invasive endoscope based abdominal procedures provide potential advantages over conventional open surgery such as reduced trauma, shorter hospital stay, and quick recovery. One major limitation of using this technique is the narrow view of the endoscope and the lack of proper 3D context of the surgical site. In this paper, we propose a rapid and accurate method to align intraoperative...
متن کاملComparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction
Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
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 کاملIntra-cardiac MR imaging & MR-tracking catheter for improved MR-guided EP
Background Electrophysiology (EP) studies can diagnose & treat patients with arrhythmia. MR-guided EP is growing, driven by the ability of cardiac MRI to provide high-contrast images. For intra-procedural use, MRI provides images of the acute state of radio-frequency ablation (RFA) lesions, e.g. necrosis, edema and hemorrhage, that potentially reduce recurrences & complications [1,2]. Unfortuna...
متن کاملSpecialty Area : MR - guided Electro - Physiology Procedures
Purpose/Introduction: Real-time visualization of interventional devices using X-ray fluoroscopy during interventions is reliable, straightforward and fast. While it may be tempting to use similar approaches for MR-guided interventions, the differences between X-ray and MR force very different optimal solutions. With X-ray guidance high-speed projective imaging is performed with a device that is...
