SELF-EXPANDING MULTI-CHANNEL RF RECEIVER COIL FOR HIGH RESOLUTION INTRA-CARDIAC MRI AND METHOD OF USE

摘要

A system and method of use for a probe is disclosed that includes a self-expanding housing constructed to permit fluid flow therethrough and constructed for insertion into a subject to be imaged. A plurality of RF coils is attached to the housing to acquire MR data.

主权项

1. A magnetic resonance (MR) imaging apparatus comprising:
an intra-cardiac catheter comprising a self-expanding housing insertable into a subject to be imaged, the housing constructed to permit fluid flow therethrough and comprising a memory-type material moveable between an expanded position and a compressed position; and a plurality of RF coils attached to the self-expanding housing and configured to acquire MR data, the intra-cardiac catheter configured to automatically expand the plurality of RF coils to an expanded position from a compressed position; wherein a gap formed between the plurality of RF coils and the self-expanding housing is configured to increase RF sensitivity away from the intra-cardiac catheter.
