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 proximal first position adjacent the ultra sound transducer.

Abstract: The present invention provides a device and a method for separating particles from fluids using ultrasound, laminar flow, and stationary wave effects comprising a micro-technology channel system with an integrated branching point or branching fork, and a single ultrasound source. One of the characteristics of the invention is that the single ultrasound source, which generates the standing waves, excites the complete structure including the channel system. No special reflectors or the like are needed. Extremely thin dividers can separate the flow, thereby enhancing the effectiveness of the device. The device could be manufactured in silicon and the ultrasound energy could preferably be delivered by a piezoelectric element.

Abstract: The present invention relates to a method and an apparatus for treatment of whole blood comprising two steps, firstly, a step of extracorporeal preseparation whereby the whole blood is separated into a blood plasma rich component and a blood cell rich component and secondly, a step of collecting and/or treating the plasma rich component, e.g. performing dialysis, plasma donation or plasma-pheresis. In one embodiment of the invention, the blood plasma rich component is achieved after particle separation using an ultrasound separator comprising micro-channels formed in a plate structure.

Abstract: The invention relates to a method for measuring parameters and/or properties in a mobile medium, e.g. a liquid or a gas. If acoustic energy is transmitted into a mobile medium, a flow is initiated in the medium. This flow is measured providing information on the properties of the medium. If the medium contains bodies which reflect acoustic and/or optical signals, ultrasound or laser-Doppler is used for measuring the velocity of the bodies. The Doppler-shifted signal provides information on the viscosity of the medium and on the bodies in the medium.

Abstract: This invention relates to a novel design of a microprobe for measuring intensity distribution, instantaneous intensity values and acoustic signal shapes of ultrasound. The probe consists of a rod-shaped electrode which is fixed with the aid of an electrically and acoustically insulating material in a sleeve-shaped electrical shield. To one end surface of said device is adhered a piezoelectric film such that the film will come in contact with the end surfaces of the electrode, the insulating material and the electrical shield. As only the outer surface of the piezoelectric film is covered by an electrically conductive layer, the rod-shaped electrode on the inner side of the film will determine the active surface of the probe.
