摘要： The present invention belongs to the technical field of ultrasound therapy, and relates to a swing type high-intensity focused ultrasound therapeutic apparatus and an MRI guided high-intensity focused ultrasound therapeutic system having such a swing type apparatus. The swing type high-intensity focused ultrasound therapeutic apparatus comprises an ultrasound transducer and a moving-locating mechanism thereof, wherein said moving-locating mechanism adopts a swing mechanism which is connected to the ultrasound transducer by a supporting rod. The MRI guided therapeutic system comprises this swing type therapeutic apparatus. In the present invention, the ultrasound transducer moves freely in multiple dimensions and the moving-locating mechanism adopts a swing mechanism, so the interference generated by the MRI guided high-intensity focused ultrasound therapeutic system on the MRI apparatus is quite small and thereby the quality of the ultrasound image obtained is good.

摘要： A MRI guided high-intensity focused ultrasonic therapeutic system comprises: a MRI apparatus and a high-intensity focused ultrasonic therapeutic apparatus. Said MRI apparatus includes the first treatment bed and said high-intensity focused ultrasonic therapeutic apparatus includes an ultrasound transducer and a moving and positioning means, which drives said transducer to move in respective directions. Wherein, said moving and positioning means is placed outside of the bore of the MRI apparatus during treatment and a supporting rod, which can extend into the bore of the MRI apparatus, is connected to said moving and positioning means at one end and is connected to said ultrasound transducer at the other end. In the system provided by the present invention, said ultrasound transducer can move in multiple orientations, freely move without any limitation of space under the treatment bed, brings less interference to the MRI apparatus, fully exerts the function and efficiency of the MRI apparatus and achieves the best therapeutic effects.

摘要： This invention provides a MRI guided ultrasound therapy apparatus. It comprises a static field magnet adapted to apply a static magnetic field in an magnetic resonance volume at a predetermined disposition; at least one ultrasound energy applicator adapted to apply energy within an energy application zone at a predetermined disposition; and The mechanical positioning means for moving said ultrasound energy applicator to position the applicator so that the energy application zone intersects said magnetic resonance volume within said region of the subject. In that apparatus, the static field magnet is open at both ends or open at side. The sided open is upward or downward and the mechanical positioning means of this ultrasound energy applicator is close to and is located outside of this sided open. This invention reduces the space limitation for the mechanical positioning means of the ultrasound transducer. Meanwhile, the non-magnetic requirement on the mechanical positioning means become less greatly and particularly the problem of interference from magnetic field produced by working current of the transducer power cord to MRI system can be solved.
