Title:

A HIGH INTENSITY FOCUSED ULTRASOUND THERAPEUTIC SYSTEM GUIDED BY AN IMAGING DEVICE GUIDED

Document Type and Number:

WIPO Patent Application WO/2008/025190

Kind Code:

A1

Abstract:

A high intensity focused ultrasound therapeutic system guided by an imaging device, includes: an ultrasound therapeutic head, which contains an ultrasound transducer (8), a therapeutic bed (11), on which a patient (17) lie, and an imaging device used for imaging the focus (3). The imaging device is a 2-dimension imaging non-ultrasound imaging device. The ultrasound transducer (8) has a diameter of the focal center (23) in the biological focal zone (2) which is focalized the focus (3) is in the range of 0.1-5mm, preferably, in the range of 0.2-2mm. The non-ultrasound imaging device is CT or MRI, which has the function of 2-dimension imaging.
