摘要： A radio frequency (RF) probe for a nuclear magnetic resonance check weighing system produces uniform magnetic field at the center of RF probe , has minimal sensitivity to electrical interference from external sources, shapes the magnetic field to minimize cross coupling from packages such as drug vials not under test, and presents minimal airflow obstruction. RF probe includes a coil with a plurality of conductive loops having a rectangular cross section carried inside two opposing, rectangular cross section housings , respectively. Housings are spaced apart and in parallel, creating an 'open probe' configuration permitting a conveyor belt carrying vials whose contents are to be checked to pass between housings, and allows airflow surrounding the vials and conveyor belt to pass substantially without obstruction. Conductive loops and the housings carrying them may be placed such that the longitudinal axis of coil is oriented in either horizontal or vertical spatial relation with conveyor belt.

摘要： A radio frequency coil for transmitting or receiving signals at a magnetic resonance frequency includes an arrangement of substantially parallel rungs (70, 70', 70') and one or more generally annular strip-type end-rings (78, 78', 78', 80) disposed generally transverse to the parallel rungs and connected with the rungs. Each generally annular strip-type end-ring includes at least two conductor layers (82, 82', 82', 84, 84', 84', 86, 88) separated by a dielectric layer (72, 72a, 72b). A radio frequency shield (34) substantially surrounds the arrangement of substantially parallel rungs (70, 70', 70'). At least one of the conductor layers of each end-ring is connected with the radio frequency shield.

摘要： MR imaging method which is notably suitable for applications where an as short as possible acquisition time is desired. The method is based on the SENSE method which enables the image acquisition to be performed with a reduced FOV (field of view); parallel, multi-channel detection is then performed by means of receiving elements having different spatial sensitivity profiles. The method is based on the recognition of the fact that conventional birdcage resonators can be tuned to different resonance modes whose spatial sensitivity profiles deviate strongly. A birdcage resonator that is composed of a plurality of sub-resonators can operate simultaneously in different resonance modes at one resonance frequency and enables parallel, independent signal detection with different sensitivity profiles; this feature is used to carry out the SENSE method.

摘要： In magnetic resonance apparatus such as magnetic resonance imaging apparatus, wherein a receive coil (6) is placed adjacent to the surface of a patient (1), the coil (6) is spaced from the surface of the patient in the interests of improvement in signal-to-noise ratio with a pad (13), forming part of a structure with magnetic properties, of material having a permeability greater than that of free space at the frequency of magnetic resonance but being non-magnetic in steady magnetic fields interposed between the receive coil (6) and the surface of the patient (1), in order to guide flux from a signal source (12) in a region of interest (7) selectively along paths which couple with the receive coil (6) and therefore increase the strength of signal relative to the noise.

摘要： The invention provides a method for magnetic resonance imaging, and spectroscopic analysis of a specimen which includes positioning the specimen within a main magnetic field, introducing an antenna having a non-loop antenna portion (22) in close proximity to the specimen. Radio frequency pulses are provided to the region of interest to excite magnetic resonance signals. Gradient magnetic pulses are applied to the region of interest with the antenna receiving magnetic resonance signals, and emitting responsive output signals. A processor processes the responsive output signals to provide image information for display in a desired manner. The method in the preferred form employs a flexible antenna. The method in another preferred form involves employing an impedance matching circuit (30) electrically interposed between the non-loop antenna, and the processor to enhance radio frequency power transfer; and magnetic resonance signal to noise ratio from the non-loop antenna (22) to the processor.

摘要： There is disclosed an NMR probe including a body defining an internal chamber. This chamber is adapted for supporting a vacuum and the body is of a non-magnetic material. A conduit extends through the chamber in the body. The conduit has a first portion in communication with second portions, the first portion being intermediate the second portions, with the first and second portions of non-magnetic materials with substantially equal thermal expansion coefficients. An RF coil is positioned along at least a substantial portion of the first conduit portion. It is preferred that this device also include a field or frequency lock unit in the chamber, as well as a getter, to allow for degassing in the chamber to maintain the preferred high pressure vacuum. A method of using this NMR probe for NMR analysis is also disclosed.
