摘要： An RF coil suitable for use in imaging systems is provided which coil has a dielectric filled cavity formed by a surrounding conducting enclosure, the conducting enclosure preferably being patterned to form continuous electrical paths around the cavity, each of which paths may be tuned to a selected resonant frequency. The patterning breaks up any currents induced in the coil and shortens path lengths to permit higher frequency, and thus higher field strength operation. The invention also includes improved mechanisms for tuning the resonant frequency of the paths, for selectively detuning the paths, for applying signal to the coil, for shortening the length of the coil and for controlling the field profile of the coil and the delivery of field to the object to the image.

摘要： A nuclear magnetic resonance measurement system is disclosed which includes, in combination, means for generating an applied main magnetic field, and an array of at least two radio frequency current loops. The loops are electrically connected in parallel, and are oriented in a generally planar relationship with respect to each other. The loops are connected in phase with respect to each other so that the component of magnetization generated by the loops which orthogonal to the direction of the applied main magnetic field is in the same general direction. A capacitor is preferably electrically connected in parallel with the loops.

摘要： A method for generating a magnetic resonance image includes configuring a magnetic field to correspond to a trajectory within a region of interest. The method includes applying RF excitation to spatially control a region of magnetic resonance corresponding to the trajectory. The method includes modulating the magnetic field coincident with the spatially controlled region of magnetic resonance. The method includes acquiring data corresponding to the region of magnetic resonance and generating an image based on the data.
