Modular design of receiver coil arrays

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 Pi 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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
