Apparatus using focused ultrasound wave by controlling electronic signals and using method thereof

An extracorporeal HIFU necrosis apparatus through the control of an electronic signal, comprising:

• an ultrasonic oscillator array 100 having ultrasonic oscillation elements 110 fixed on a plane and oriented a life;
• delay circuits 120 respectively connected to the oscillation elements 110 for delaying ultrasonic oscillation by a delay time;
• an ultrasonic oscillator including control means 150 for controlling the delay time so that the ultrasonic beams are focused;
• and
• 3-D image diagnosis means 170 for measuring the shape of a target tissue 30 within the life and outputting the measured shape as a 3-D image,
• wherein the control means 150 controls the delay time of the delay circuits 120 based on a positional data of the 3-D image in order to focus the ultrasonic beams on the target tissue 30.

A method of employing an extracorporeal HIFU necrosis apparatus through the control of an electronic signal, the method comprising:

• a step (S100) of allowing 3-D image diagnosis means 170 to measure a shape of a target tissue 30 within a life and output a measured shape as a 3-D image;
• a step (S140) of allowing control means 150 to control delay time of each of delay circuits 120 connected to an ultrasonic oscillator array 100 based on a positional data of the 3-D image;
• a step (S180) of allowing the control means 150 to oscillate the ultrasonic oscillator array 100;
• and
• a step (S200) of making the target tissue 30 necrotized by focusing an oscillated ultrasonic wave on the target tissue 30 depending on a difference of the delay time.
