Abstract: A dual frequency coil package system for use in transmitting and receiving at least two frequencies in an MRI system, including a frequency converter coupled to the MRI system to receive a first frequency through the local transmit coil port and convert the first frequency to a second frequency, a second frequency transmit coil to receive the second frequency from the frequency converter and to transmit the second frequency, a dual tuned receiver coil to receive and to output the at least two frequencies, and a switchable receiver to receive the at least two frequencies output from the dual tuned receiver coil and to transmit the first frequency received from the dual tuned receiver coil directly to the MRI system, and to convert the second frequency received from the dual tuned receiver coil to the first frequency before transmission to the MRI system.

Abstract: An MRI antenna array including a housing and a substrate, antenna elements and circuitry encapsulated by the housing. The housing, antenna elements, and substrate are flexible to allow the housing to distort in three dimensions to closely conform to contours of a patient. The antenna elements may be formed from a flat weave mesh conductor. The flat weave mesh conductor allows the MRI antenna array to conform to the contours of a patient to provide three dimensional movement of the array. The flat weave mesh conduct has increased durability over a tight weave mesh of an elongate hollow cylinder conductor, allowing the flat weave mesh conductor to withstand additional flexing cycles.

Abstract: An MRI antenna array including a housing and a substrate, antenna elements and circuitry encapsulated by the housing. The housing, antenna elements, and substrate are flexible to allow the housing to distort in three dimensions to closely conform to contours of a patient. The antenna elements are mounted to the substrate in a manner that permits each element to maintain a desired resonance when the housing is distorted in three dimensions. The circuitry is electrically coupled with the antenna elements to maintain tuning and isolation of the elements when the housing is distorted in three dimensions. The housing, antenna elements, and substrate may be elastic to allow the housing to be worn by a plurality of different sized patients so that the housing is in close contact with the patient and conforms to contours of the patient.
