The ultrasonic system of the present invention uses a microwave beamforming architecture, which can disassemble the multi-channel delay circuit into two circuits of fine delay and coarse delay. Through multi-stage input signal delay and summation, the signal at the probe end can be effectively reduced. The amount of data and hardware complexity meet the needs of system miniaturization. Moreover, the present invention only uses a single microwave beamformer to realize the fine delay calculation of beamforming, and cooperates with the multi-line coarse delay beamforming operation to meet the requirements of multi-line imaging； the setting values of fine delay and coarse delay are also compensated and Correction to maintain the accuracy required for multi-line beam focusing on the delay time of each channel.本發明之超音波系統使用微波束成形的架構，能將多通道的延遲電路拆解成精細延遲與粗略延遲兩個電路，透過多階段的輸入信號延遲與加總，而有效降低探頭端的的信號資料量與硬體複雜度，達到系統小型化的需求。且本發明僅使用單一微波束成形器來實現波束成型的精細延遲運算，並搭配多線的粗略延遲波束成形運算來達到多線成像的需求；對精細延遲與粗略延遲的設定值亦進行補償與修正，來維持多線波束聚焦在各通道延遲時間所需的精準度。
