METHOD USING TRANSMITTED AND RECEIVED SIGNALS FOR FORMING ULTRASONIC IMAGES FOR ULTRASONIC DIAGNOSIS, AND HIGH INTENSITY FOCUSED ULTRASONIC THERAPEUTIC DEVICE PERFORMING SAME

摘要

The present disclosure relates to a method for forming ultrasonic images using transmitted and received signals for ultrasonic diagnosis and a HIFU therapeutic device performing the same. The HIFU therapeutic device includes a transceiver for transmitting a diagnostic ultrasound to a subject, and receive a reflected subject ultrasonic echo signal to form a received signal; an image processor for forming a B-mode image based on the received signal and output the B-mode image through a display unit; an ultrasonic wave generator for transmitting a high intensity ultrasound to a specific area of the subject; and a control unit for enabling the transceiver and the ultrasonic wave generator to control transmission periods of the diagnostic ultrasound and the high-intensity ultrasound wave based on information on at least one of a prescribed HIFU PRF (Pulse Repetition Frequency) and duty ratio and a PRF disable signal generated by the ultrasonic wave generator.
