A HIGH INTENSITY FOCUSED ULTRASOUND SYSTEM FOR SCANNING AND CURING TUMOR

Title:

A HIGH INTENSITY FOCUSED ULTRASOUND SYSTEM FOR SCANNING AND CURING TUMOR

Document Type and Number:

WIPO Patent Application WO/1999/037364

Kind Code:

A1

Abstract:

A HIFU (high intensity focused ultrasound) system for scanning and curing tumor, consists of a combined sensor, a power, a B-ultrasonic generator, a multidimensional digital control moving apparatus, a vacuum dehydrating apparatus, a therapeutic bed and a computer. The combined sensor consists of B-ultrasonic sensor and focused ultrasonic generator sensor, the ultrasonic emitting end of which is mounted on the multidimensional digital control moving apparatus. The said moving apparatuses execute scanning movement out the body under the controlling of computer. So, the HIFU region (space) generated by therapeutic sensor move and scan in body, acted by HIFU on, histiocyte in this region is cavitated and surged (vibrated), and the temperatures of this region rise upon 70 °C instantly, so histiocyte in this region is denaturalized and necrosed. Then, the object of this curing tumor in the body is achieved by scanning movement out the body.
