摘要： The HF antenna system of a nuclear resonance device includes a plurality of antenna elements arranged one behind another in the direction of a longitudinal axis of the system, that are mutually at least largely magnetically decoupled and each connected to a transmitting and/or receiving device. To improve the axial field profile, the antenna elements are each cage-shaped with two end-located conductor rings, between which a plurality of conductor pieces extend at least approximately parallel to the longitudinal axis. Preferably the antenna system is composed of three or five antenna elements.

摘要： A high-frequency apparatus for nuclear spin tomography includes a high-frequency antenna arrangement in the region of a biological body to be imaged. Such an apparatus often exhibits an undesirable electric field coupling between the antenna arrangement and the body. To avoid the effects of such a coupling, the present invention provides at least one plate-shaped or layer-shaped shielding element consisting of a dielectric material with an .epsilon..sub.r of at least 50 and a tan .delta. of at most 2.5.times.10.sup.-2. This shielding element is arranged at least in a region of increased electric field strength prevailing on the antenna arrangement.

摘要： A magnetic resonance RF field is produced in a magnetic resonance imaging system that includes a main magnetic field apparatus and an object-bearing table movable relative to the main magnetic field apparatus and on which a local coil system is arranged. The local coil system includes a plurality of transmission elements. A current location of the object-bearing table relative to the main magnetic field apparatus is established. The transmission elements are automatically connected based on the current location of the object-bearing table.

摘要： The present application is directed to methods and systems for tapping online resources to design a clinical trial and/or recruit participants for the clinical trial. In one embodiment, a system for using online resources to design a clinical trial and/or recruit participants includes one or more web crawlers. Each of the web crawler may be configured to collect data related to one or more specified topics during a community identification phase. A data engine of the system processes the collected data into filtered, relevant information that identifies communities of individuals suitable for recruitment. A patient discovery module may, in a patient discovery phase, develop or use a survey to further target interested patients for recruitment and collect information for designing a suitable study or trial. The system may, in an assessment and communication phase, design a study which may be self-managed by the recruited patients. The study may provide feedback for refining or modifying any one of the above phases. The study may also aim to address certain issues faced by the recruited patients, such as ensuring compliant use of a drug, elimination of side-effects, and using a modified therapy to improve the effectiveness of a drug, etc.
