Abstract: A magnetomotive imaging probe device and method is described. The probe device includes a housing having an outer surface and an inner cavity; a magnet; a sensing device configured to detect distance, movement, or magnetic material. The magnet is arranged in the inner cavity of the housing and the sensing device on the outer surface of the housing, and the magnet is arranged to generate a time-varying magnetic field at an imaging plane of the sensing device. The magnet is intended to move magnetic nanoparticles in tissue such that a movement can be detected with the sensing device (ultrasound, optical or other). The detected motion infers the presence of magnetic material (nanoparticles).

Abstract: A magnetomotive imaging probe system is disclosed comprising a movable probe, a magnet arranged on the probe, and an ultra sound transducer, wherein the magnet is arranged to generate a time-varying magnetic field (T) at an imaging plane (304) of the ultrasound transducer, distally of the ultra sound transducer and the probe, when the probe has a proximal first position adjacent the ultra sound transducer.
