An ultrasound system includes a probe for providing an ultrasound signal associated with an object, a host and a location detecting module. The host includes an image processing unit, a screen, and a control unit. The image processing unit is configured to receive and process the ultrasound signal, thereby generating an ultrasound image. The screen includes a first region for displaying the ultrasound image and a second region for displaying an operational interface. The control unit is configured to adjust the locations of the first region and the second region on the screen according to location information. The location detecting module is configured to acquire the location information by detecting the movement of the probe with respect to the screen.超音波系統包含一探頭、一主機，以及一位置偵測模組。探頭用來提供相關於一物體之一超音波訊號。主機包含一影像處理單元、一螢幕以及一控制單元。影像處理單元用來接收並處理來自探頭的超音波訊號以產生對應該物體之超音波影像。螢幕包含一第一區域和一第二區域，用來在第一區域內顯示超音波影像，以及在第二區域內顯示一操作介面。控制單元依據一位置資訊來調整第一區域和第二區域在螢幕上之顯示位置。位置偵測模組用來偵測探頭對應於螢幕之位置變化以得到位置資訊。
