摘要： The present invention is directed to a coil assembly capable of producing a flexible FOV for use with an MRI system. The coil assembly includes a gradient coil disposed about an imaging axis and a plurality of higher order gradient coils, or shim coils, positioned about the primary gradient coil such that the plurality of higher gradient order coils have a radius greater than the radius of the primary gradient coil. A change in the FOV is realized by modulating the current in the higher order gradient coils or shim coils.

摘要： The invention relates to calculating an estimate representing noise and signal quality, and to a receiver of a radio system. The highest value of a correlation vector is compared either to the second highest value or to the mean value of the other values. If a specific spreading code is used in the reception of the signal, the comparison forms a ratio of the signal and disturbance, the ratio being applicable particularly to combining signals from the diversity branches of a diversity receiver, whereby the method makes it possible to combine the signals even prior to detection. If the reception employs a spreading code with which no signal received by the receiver has been transmitted, it is possible by comparing the correlation values to form a noise quality estimate, an estimate value higher of which meaning that the receiver is receiving a signal and not just noise.
