The invention relates to a filtering apparatus () for filtering an ultrasound signal, which is influenced by an electrical unit and comprises a first part including information about an object () from which the ultrasound signal has been received and a second part not comprising information about the object. A correction signal determination unit () determines a correction signal being indicative of the influence of the electrical unit on the ultrasound signal from the second part of the ultrasound signal and a correction unit () corrects the first part of the ultrasound signal based on the determined correction signal for filtering the influence of the electrical unit out of the ultrasound signal. Since the correction signal is indicative of the influence of the electrical unit, wherein the correction signal is used for correcting the ultrasound signal, unwanted interference visible in the unfiltered ultrasound signal can be filtered out.

Filtering apparatus for filtering an ultrasound signal

A fiber scanning system is provided comprising a housing () with a fiber (), the fiber () comprising a fixed part and a free end, the fixed part being attached to a bottom of the housing () and the fiber () extending parallel to the wall of the housing (). At least one electrical coil () is attached to the wall at a position in between the fixed part and the free end of the fiber (), a winding of the electrical coil () being in a plane parallel to the fiber (). A magnet () is attached to the fiber (), such that the electrical coil () may induce a force on the magnet (). The magnet () is attached to the fiber () at a position just before or after the electrical coil (), a width of the magnet () being such that the magnet () extends over the electrical coil ().
