Embodiments described herein relate to detectors and their method of use for sensing electromagnetic fields, electromagnetic signals, biochemical analytes, and/or other conditions in subjects. The device may include an inductively-coupled implantable coil-based transducer that converts electrical, photonic, biochemical signals, and/or other appropriate signals and/or conditions originating in tissues and/or transplanted tissue grafts into changes in a property of the transducer, such as a resonance frequency, that may be detected using an alternating magnetic field that may be provided by a magnetic resonance imaging (MRI) signal and/or other appropriate source. In some embodiments, the detector comprises a FET that changes state upon detection of a subject condition of interest. The change in the FET may change the resonance frequency of an associated LC or RLC circuit. The change in resonance frequency may change the brightness and/or intensity of the detector when detected by an MRI scanner or other appropriate scanner.

The present disclosure provides a magnetic resonance imaging (MRI) radio frequency (RF) coil assembly. The MRI RF coil assembly may include one or more coils and one or more control circuits. Each of the one or more coils may include a first end and a second end. Each of the one or more control circuits may electrically connect the first end and the second end of one of the one or more coil. Each of the one or more control circuits may be configured to adjust an operation of the coil that is electrically connected with the control circuit based on an input control signal. The one or more control circuits may be located at different regions.

A method for ascertaining at least one of a position or an orientation of an MR local coil unit for arrangement inside a main magnetic field includes providing a first 3D relative position of a reference sensor system in relation to the main magnetic field; receiving an acceleration vector from at least one acceleration sensor; retrieving a distance vector describing a fixed relative position as a function of the received acceleration vector; calculating a second 3D relative position of the at least one acceleration sensor in relation to the main magnetic field based on the first 3D relative position and the retrieved distance vector; and ascertaining the at least one of the position or the orientation of the MR local coil unit using the first 3D relative position and the second 3D relative position.

A flexible radiofrequency receiving coil array. The flexible radiofrequency receiving coil array is provided on a flexible panel and comprises several rows of coil units. Adjacent two rows of coil units in the several rows of coil units are alternately arranged. Preamplifiers are provided in the coil units. In the flexible radiofrequency receiving coil array, two preamplifiers in adjacent two coil units are provided on a same preamplifier mounting plate on the flexible panel, where multiple preamplifier mounting plates are provided on the flexible panel, and the preamplifier mounting plates of different columns and rows are linearly arranged. The flexible radiofrequency receiving coil array effectively reduces the distribution density of the preamplifiers, ensures the flexibility and maximum degree of distension of the coil array, and improves the fit of the coil array to the human body, thus increasing image signal-to-noise ration and image quality.
