Abstract:
1. An MRI guided high-intensity focused ultrasound therapy apparatus, comprising, a) a static field magnet adapted to apply a static magnetic field in a magnetic resonance volume at a predetermined disposition; b) at least one ultrasound energy applicator adapted to apply energy within an energy application zone at a predetermined disposition; and c) a 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 a region of a patient to be treated, wherein said static field magnet is open at both ends and open at one side, and, during treatment, the patient to be treated is fixed and positioned in a magnetic gap of the static field magnet, the open at side is either upward or downward, and the mechanical positioning means of said ultrasound energy applicator is close to and outside of said open at side, and said ultrasound energy applicator is also located outside of the open at side.
