摘要:
An apparatus and method which produce a magnetic field gradient by physically rotating one or more permanent magnets near an object in order to obtain images of the object.
摘要:
An apparatus and method are provided for spatially-selective administration of actions by at least one device in the body using a transducer that is sensitive to a spatially-variant energy field imposed on the at least one device by a source external to a subject's body; and at least one component in the at least one device, wherein interaction of the transducer with the imposed spatially-variant energy field causes or enables at least one component in the at least one device to affect nearby tissues in the body.
摘要:
An apparatus and method apply magnetic fields by generators external to a body or body part with sensors within an in vivo source that are sensitive to applied magnetic fields Through the use of these applied magnetic fields and sensitive sensors, disclosed embodiments can realize much better spatial resolution than is conventionally possible.
摘要:
Disclosed embodiments assay for the presence of Ge-68, although disclosed embodiments can also be used for other radionuclide generators, with minimal adjustments.
摘要:
An apparatus and method for magnetic particle manipulation enables the particle to be rotated and translated independently using magnetic fields and field gradients, which produce the desired decoupled translational and rotational motion. The apparatus and the method for manipulation may be implemented in parallel, involving many particles. The rotational magnetic field used to induce rotational motion may be varied to induce particle motion, which is either in phase or out of phase with the rotational magnetic field. The magnetic fields and gradients described herein may be generated with permanent magnets, electromagnets, or some combination of permanent magnets and electromagnets.
