摘要： A focusing method plays a big role of determining a resolution of an ultrasonic image. Focusing is performed by controlling an arrival difference of a signal up to a focal point by an electronics delay circuit. Here, the focusing method for focusing an ultrasonic signal having emitted to a focal point of an object via an array transducer including a plurality of elements, obtains an optimal focusing time delay curve according to the ultrasonic signal travelling velocity to thereby obtain an optimal ultrasonic image. Using only data obtained without any modification of the structure of an existing ultrasonic imaging system, a focusing time delay curve is estimated. Thus, a resolution can be enhanced with only a simple calculation.
