In-room ultrasound fusion combined with fully compatible 3D-printed holding arm – rethinking interventional MRI
There is no real need to discuss the potential advantages - mainly the excellent soft tissue contrast, nonionizing radiation, flow, and molecular information - of magnetic resonance imaging (MRI) as an intraoperative diagnosis and therapy system particularly for neurological applications and oncological therapies. Difficult patient access in conventional horizontal-field superconductive magnets...
متن کاملFusion of Intracardiac Ultrasound with 3D Cardiac C-Arm CT from Animal Data for Electrophysiology
In Electrophysiology catheter ablation is an established treatment for cardiac arrhythmias. Nevertheless, complicated ablation procedures such as Pulmonary vein isolation for atrial fibrillation treatment are difficult to learn. This can be improved by a better integration of the image modalities available today and in the future Electrophysiology lab. In this paper, we present a method to regi...
متن کاملMultifunctional interventional devices for MRI: a combined electrophysiology/MRI catheter.
The design and application of a two-wire electrophysiology (EP) catheter that simultaneously records the intracardiac electrogram and receives the MR signal for active catheter tracking is described. The catheter acts as a long loop receiver, allowing for visualization of the entire catheter length while simultaneously behaving as a traditional two-wire EP catheter, allowing for intracardiac el...
متن کاملMultimodal image fusion in ultrasound-based neuronavigation: improving overview and interpretation by integrating preoperative MRI with intraoperative 3D ultrasound.
OBJECTIVE We have investigated alternative ways to integrate intraoperative 3D ultrasound images and preoperative MR images in the same 3D scene for visualizing brain shift and improving overview and interpretation in ultrasound-based neuronavigation. MATERIALS AND METHODS A Multi-Modal Volume Visualizer (MMVV) was developed that can read data exported from the SonoWand neuronavigation system...
متن کاملPET and MRI-guided focused ultrasound surgery for hypoxic-tissue ablation combined with radiotherapy in solid tumors
Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...
