Abstract
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.
