Title:
METHOD AND DEVICE FOR REMOVING AN HIFU INTERFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2013/055129
Kind Code:
A2
Abstract:
The present invention relates to a method of removing an HIFU interference signal. The method of the present invention is characterized by transmitting ultrasonic image signals while transmitting at least two HIFU signals out of phase, receiving ultrasonic signals including reflected HIFU signals and ultrasonic image signals when at least two HIFU signals and ultrasonic image signals are reflected from an object, summing the received ultrasonic signals, and removing basic frequency components and harmonic frequency components from HIFU signals in the received ultrasonic signals. The method of the present invention may acquire a monitor image from which HIFU interference is removed regardless of an HIFU length because a pulse inversion technique is used.
