A device () positions an ultrasound transducer () for ultrasound therapy to focus a treatment beam () emitted by the ultrasound transducer () at tissue of interest. The device () includes at least three anchors () which support the ultrasound transducer (). The device () further includes at least three extendable structures (), each with a coupling () that supports a corresponding one of the at least three anchors (). A drive mechanism () of the device () independently drives each of the at least three extendable structures () towards or away from a subject to move the ultrasound transducer () within at least three degrees of freedom.

A radiation force balance calibrator () for calibrating a high intensity focused ultrasound transducer (), the radiation force balance calibrator comprising: a balance frame (); a force sensor () for measuring force, wherein the force sensor is attached to the balance frame; a balance () with first () and second ends (), wherein the first end is attached to a pivot () for enabling the balance to pivot relative to the balance frame, wherein the second end is adapted for exerting force onto the force sensor; an oil target phantom () connected to the balance for absorbing ultrasound radiation () from the high intensity focused ultrasound transducer, wherein the absorption of ultrasonic radiation causes a reduction in the force exerted by the balance on the force sensor; and wherein the radiation force balance calibrator is constructed of non-magnetic materials.

An RF/MR transmit and/or receive antenna is disclosed for use in a hybrid magnetic resonance imaging (MRI) system (or MR scanner), which comprises an MRI system and another imaging system for example in the form of a high intensity focused ultrasound (HIFU) system. The RF transmit and/or receive antenna () is provided with respect to its conductor structure such that it does not disturb or in any other way detrimentally influence the related other (i.e. HIFU) of the two systems, especially if both systems are operated simultaneously and if the RF antenna is positioned in close proximity to an object to be imaged.
