摘要： A plurality of magnetic field induction coils and a radio frequency (RF) detection coil are supported by a frame which is inserted into the bore of an MRI system to detect magnetic fields produced by gradient pulses and RF pulses produced during a scan. The detected magnetic fields are processed to produce gradient waveforms and RF pulse waveforms that are displayed to the user.

摘要： An apparatus for receiving magnetic resonance (MR) signals emitted by an imaging subject includes a receiver coil configured to detect the MR signals and a frequency translating preamplifier coupled to the receiver coil. The frequency translating preamplifier is configured to amplify the MR signals and to convert a frequency of the MR signals to an intermediate frequency. The frequency translating preamplifier may include an amplifier having a predefined gain, a frequency filter configured to filter at least one predetermined frequency and a mixer configured to convert the frequency of the MR signals to the intermediate frequency.

摘要： A method, system, and apparatus including a magnetic resonance (MR) coil system that includes an MR coil element, a high input Pre-amplifier having a high input impedance field-effect-transistor (FET) with an impedance of one of substantially equal to 500 ohms and greater than 500 ohms, and a conductive path. The conductive path has a first end coupled to the MR coil element and a second end coupled to the high input Pre-amplifier such that the MR coil element is coupled in series with the high input Pre-amplifier. Further, the conductive path is free of a matching network intervening between the MR coil element and the high input Pre-amplifier.

摘要： A gamma ray detector ring for a combined positron emission tomography (PET) and magnetic resonance imaging (MRI) system is integrated into a radio frequency (RF) coil assembly such that the detector ring is integrated with a RF shield. Each gamma ray detector in the detector ring includes a scintillator component that emits light when a gamma ray is detected and a photodetector component designed to be sensitive to the frequency of light produced by the scintillator. A RF shield may be integrated into a detector ring such that the RF shield is positioned between the scintillator and photodetector components of each detector, thereby saving valuable radial space within the imaging system. Multiple such detector rings may be located adjacent to one another to increase axial coverage and enable three-dimensional PET imaging techniques.
