    • PURPOSE: An ultrasound signal processing method for removing an HIFU(High Intensity Focused Ultrasound) signal and an ultrasound signal processing apparatus are provided to produce an intermediate frequency of an ultrasound image signal to minimize interference of the HIFU signal in the ultrasound image signal. CONSTITUTION: An HIFU signal and an ultrasound image signal are transmitted(210). An ultrasound signal including the HIFU signal and the ultrasound image signal are received twice(220). A basic frequency element and an odd harmonic frequency element of the HIFU signal are removed by adding the ultrasound signals which are received twice(230). A B-mode image is generated from the ultrasound signal(240).

    • PURPOSE: An ultrasonic wave signal beam former and a beam forming method using the same are provided to reduce hardware complexity even though the hardware complexity increases if a sampling frequency is higher than an existing frequency. CONSTITUTION: An ultrasonic wave signal beam former comprises the following units. A sampling unit samples an ultrasonic wave signal by a sampling frequency which is N times higher than a central frequency that an array converter has. The array converter receives an ultrasonic wave signal reflected from a collection point. A memory unit stores the ultrasonic wave signal sampled in the sampling unit. A time delay calculating unit calculates a time delay value for selecting an ultrasonic wave signal to be interpolated among ultrasonic wave signals stored in the memory unit.
