An ultrasound probe includes a matching element, a backing layer, a piezoelectric element and a driver. The piezoelectric element is disposed between the matching element and the backing layer. The driver generates a coding wave inputted to the piezoelectric element, such that the piezoelectric element outputs a focusing sonic wave field in a short axis.超音波探頭包括匹配元件、背後層、壓電元件及驅動器。壓電元件設於匹配元件與背後層之間。驅動器產生編碼波形並輸入至壓電元件,使壓電元件沿短軸輸出聚焦音波場。
