✦ Synopsis

Abstract

We describe a modular and hence flexible system for connecting MR surface coils to create a receiver array. Up to 16 individual coils of different size and shape depending on the application are plugged into a connector box that houses the control electronics. Preamplification, matching and detuning circuitry are housed on a circuit board directly attached to each coil loop. Electrical adjustments for tuning or decoupling for each coil configuration are not needed thanks to effective preamplifier decoupling provided through a Π matching network. Radio‐frequency safety and electrically stable cabling are ensured by multiple radio‐frequency traps. Array modules for 1.5 and 3 T have been simulated, constructed, tested, and used for imaging experiments. Copyright © 2007 John Wiley & Sons, Ltd.

## Abstract A lightweight 32‐element MRI receiver‐coil array was designed and built for cardiac imaging. It comprises an anterior array of 21 copper rings (75 mm diameter) and a posterior array of 11 rings (107 mm diameter) that are arranged in hexagonal lattices so as to decouple nearest neighbors

Specialized receiver coils having a small sensitive region can provide an improvement in SNR for MR imaging and spectroscopy, at the expense of limiting the usable field of view. This work presents a technique for designing coil arrays that allows the size and location of the sensitive region to be

In this study we present a method to simulate complex phased array coil designs for cardiac imaging. It is based on the combination of numerically calculated B 1 field vectors for each coil of the array and a noise resistance data set, which is acquired only once with a set of test coils. This techn
