Method using transmitted and received signals for forming ultrasonic images for ultrasonic diagnosis, and high intensity focused ultrasonic therapeutic device performing same

Abstract

The present invention relates to a method using transmitted and received signals for forming ultrasonic images for ultrasonic diagnosis, and to a high intensity focused ultrasonic therapeutic device performing same. The high intensity focused ultrasonic therapeutic device includes: a transmitting and receiving unit for transmitting ultrasonic waves for diagnosis to a subject and receiving an ultrasonic echo signal reflected from the subject to form a reception signal; an image processing unit for enabling a B-mode image to be formed on the basis of the reception signal, and outputting the B-mode image through a display unit therein; an ultrasonic wave generating unit for transmitting high intensity ultrasonic waves to a specific region of the subject; and a controller for controlling the transmitting and receiving unit and the ultrasonic wave generating unit to control the transmission periods of the ultrasonic waves for diagnosis and the high intensity ultrasonic waves on the basis of at least one or more pieces of information on the pulse repetition frequency (PRF) of the high intensity ultrasonic waves, the preset duty ratio, and the PRF disable signal generated by the ultrasonic wave generating unit.

Problems solved by technology

[0004] The existing high-intensity ultrasound treatment method is to transmit ultrasound to the biological tissue that needs to be treated to obtain images, and obtain images through the echo signals reflected by the biological tissue. However, when the target biological tissue changes are sensed by high-intensity ultrasound, due to High-intensity ultrasonic interference cannot accurately identify the target object
