An ultrasound scanning system includes an ultrasound scanning device, an ultrasound probe and an image capturing unit. The ultrasound probe includes a casing, a communication unit and an ultrasound scanner. The ultrasound scanner emits an ultrasound signal to a target and receives the ultrasound signal reflected by the target, wherein the ultrasound signal is transmitted to the ultrasound scanning device through the communication unit. The image capturing unit captures a partial image of the target and transmits the partial image to the ultrasound scanning device. The ultrasound scanning device generates an original ultrasound image according to the ultrasound signal and assigns a first color to an object of the original ultrasound image. The ultrasound scanning device calculates a second color of the partial image and converts the first color into the second color.一種超音波掃描系統,包含一超音波掃描儀、一超音波探頭以及一攝像單元。超音波探頭包含一殼體、一通訊單元以及一超音波掃描器。超音波掃描器對一標的物發出一超音波訊號且接收自標的物反射之超音波訊號,其中超音波訊號經由通訊單元傳送至超音波掃描儀。攝像單元擷取標的物之一局部影像,且將局部影像傳送至超音波掃描儀。超音波掃描儀根據超音波訊號產生一原始超音波影像,且賦予原始超音波影像中之一物體一第一顏色。超音波掃描儀計算局部影像之一第二顏色,且將第一顏色轉換為第二顏色。1‧‧‧超音波掃描系統10‧‧‧超音波掃描儀12‧‧‧超音波探頭14‧‧‧纜線100‧‧‧顯示器120‧‧‧殼體124‧‧‧超音波掃描器126‧‧‧攝像單元
