摘要： An imaging system is provided for locating implants within a patient, and for determining the spatial relationship and orientation between components of an implant within a patient. Magnets are fixed to an implant in pre-determined locations, the magnets having pre-determined quantity, magnetic field map, and moment orientations. An array of sensors is arranged around the implant. The locations of the magnets are estimated by iteratively solving for the position vector coordinates using multi-poles approximating the pre-determined quantity, magnetic field map, and moment orientations of the magnets and the magnetic field measurements for each sensor. The positions and orientations of the implant or components of the implant are inferred from the estimated locations of the magnets.

摘要： A method of separating a target biological analyte from a mixture of substances in a fluid sample employs nonlinear magnetophoresis. Magnetic particles having the capacity to bind to the target analyte are contacted with the fluid sample so that the analyte is immobilized on the surface of at least some of the particles. The magnetic particles are provided adjacent an array of micromagnets patterned on a substrate so that the particles are attracted the micromagnets. The magnetic particles are then subjected to a traveling magnetic field operating at or above a frequency effective to sweep those particles not bound to analyte to an adjacent micromagnet. Those magnetic particles bound to analyte have a larger size or smaller magnetic moment that prevents them from being moved to adjacent micromagnets, thereby affording separation of the analyte.
