METHOD FOR COHECTING ULTRASONICS IMAGE SIGNAL

摘要

This invention relates to a focusing method of ultrasound imaging signal in ultrasound imaging system. This new focusing method can perform the continuous dynamic focusing by eliminating the analog delay device and also has excellent resolution and simple structure. In the method for focusing the ultrasound imaging signal, the ultrasound signal which is reflected from the object is converted into electrical signal in the array transducer formed of N transducing devices. The differences of delayed time among the ultrasound signals are compensated by the sampling-delay method. The time dealys occur due to the difference among the array position of transducing devices.
