摘要： Biological data, such as human heart rate data, is acquired and processed in a non-linear manner to facilitate an assessment of the physiological state of the subject, and/or to assist in predicting incipient disorders or instability. Determinism, laminarity and recurrence measures are derived for a rolling sample of a time series of said data. The recurrence measure can be the Euclidean threshold (εthresh) at a given recurrence rate. A representation, such a colour coded matrix or multi-dimensional vector, is formed from a combination of the derived determinism, laminarity and recurrence measures. The representation can then be analysed to detect indicators of physiological instability, such as arrhythmia, or to discriminate between arrhythmias. The analysis may be performed visually, or in an automated manner in real time, such as in an ambulatory or implanted device, or post hoc by a bedside monitor.

摘要： Magnetic resonance systems are provided which employ a shielded, asymmetric magnet to produce an offset dsv. The magnets include at least a first coil C1, which carries current in a first direction, and two coils C2 and C3, which are located at least in part within the internal envelope EC1 defined by the first coil and which carry current in an opposite direction to the first coil. The magnets are shielded by a shielding coil C4, which carries current in a direction opposite to that of the first coil, and/or a ferromagnetic structure (FS). The magnets can include additional coils, such as a fifth coil C5 at the magnet's distal end. The magnets can be used in, for example, orthopedic imaging.

摘要： Bi-planar coil assemblies are disclosed which have DSV's whose centers are offset by distances D from the origins of x,y,z-coordinate systems, where said origins of x,y,z-coordinate systems are coincident with the geometric centers of the coils. The distances D can be of the order of 10-20 centimeters or more. The bi-planar coil assemblies can be used in MRI applications to reduce the feeling of claustrophobia experienced by some subjects. The assemblies also can facilitate the imaging of various joints, including the wrist, elbow, ankle, or knee.

摘要： A coil for a magnetic resonance imaging device consists of multiple coil elements arranged about an imaging space. Each coil element comprise radiating structures oriented at an angle to a tangent of the imaging space. Angling the radiating structures reduces mutual coupling between coil elements and enhances the penetration of the radio frequency field to the imaging space.

摘要： A radio frequency (RF) coil array is used in resonance imaging and/or analysis of a subject located within a cylindrical space in which a magnetic field is operatively applied in an axial direction (z). The coil array comprises a plurality of coil elements (10, 11, 12, 13) angled relative to each other about the axis of the cylindrical space, each coil element having a pair of main conductors extending generally parallel to the direction of the magnetic field and located on diametrically opposite sides of the cylindrical space, and a pair of connection conductors connected between respective ends of the main conductors. Each coil element has its maximum sensitivity near the centre of the cylindrical space, so that the subject under study is located in a region of maximum sensitivity.
