Abstract
Magnetic particle actuating systems may include a magnet system configured to generate a magnetic field that includes a field-free region. A corresponding control system can be configured to control the magnet system to create a field-free region at least partially matching a target region. An excitation system can be configured to generate an excitation field to cause actuation of magnetic nanoparticles in an actuation region.
Claims19
A computer program product comprising a non-transitory, machine-readable medium storing instructions which, when executed by at least one programmable processor, cause operations comprising:
- generating a magnetic field with a magnet system, the magnetic field including a field-free region enclosing a target region within the field-free region, the generating of the magnetic field utilizing coils with currents flowing in opposite directions to generate opposing magnetic fields;
- and
- applying an excitation field with an excitation system to cause actuation of magnetic nanoparticles in an actuation region.
