Introduction

There four topics in the group of Next Generation MRI.

1.Wideband MRI

2.HTSC

3.Phased Array Coil

RF Coil is one of the key factors that determine the quality of Magnetic Resonance images. Signal-to-Noise Ratio (SNR) and Field of View (FOV) are two important attributes of coil design, and Interventional MRI applications impose higher requirements for both than normal imaging. In order for an MRI system to provide image guidance during an ablation or biopsy procedures, not only imaging speed needs to be fast enough to allow for real time image update, but also the target treatment area can be focused and zoomed to show greater detail. Furthermore the configuration or placement of the coil(s) needs to be “open” to allow various therapeutic and biopsy devices to be applied to patient during operation. The use of a surface coil or a cable-less version would be the choice.

In a more advanced MRI system, multiple coils have been employed in a volumetric configuration, in a phased array or parallel imaging scheme to improve FOV coverage or to increase imaging speed respectively. Parallel imaging system provides some advantage in SNR and imaging speed, but also introduces added complication due to the presence of multiple coils. We intend to address some of the issues involved in making a surface coil work on top of a multiple coil configuration and to be compatible with the parallel imaging scheme. The specific aim of the project is to develop a dedicated RF receive coil optimized for liver tumor ablation procedures using HIFU under MRI guidance.

In this three year project, we plan to complete the design and make a prototype to work on a selected MRI system in the first year, so it can subsequently be used in the second year in the integration test with the rest of the integrated MR-guided ablation platform. Also from the second year, we will explore the feasibility of a cable-less design to further make the treatment area more accessible during the interventional procedure
