NOVEL PARALLEL TRANSMIT SYSTEMS FOR MRI APPLICATIONS
… a new RF transmitter design is presented for MRI parallel transmissionapplications. Benchtop measurements and imaging experiments were performed withdifferent prototypes to prove system’s performance and potential advantages versus asystem based on conventional MRI RF hardware. The degrees of …

Visualisierung von Instrumenten in der interventionellen Kernspintomographie
The term interventional MRI (magnetic resonance imaging) identifies a methodology where MR imaging is used to guide therapeutic procedures. A basic prerequisite for such interventions is the visualization of the applied instruments (i.e. catheters and needles) in the acquired MR images. This …

3D Reconstruction of Tubular Structures Using MRI Projection Images
… one on simulation and two on experiments with MRI projection images. First, a MATLAB simulation was created to analyze the reconstruction process; it was tested with different shapes of the structures and different numbers of projections. Second, triplanar projection imaging was evaluated on a …

Novel Tools for Interventional Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) provides unique advantages such as superior soft tissue contrast, true multiplanar imaging, variable contrast mechanisms, measurement of temperature changes, perfusion and diffusion, and no ionizing radiation. Despite considerable research efforts in the field of …
