The present invention is directed to an ultrasound system. The ultrasound system of the present invention includes an ultrasound diagnostic unit (150), a storage unit (130), an image acquisition unit (110), a pattern recognition unit (120), and a control unit (140). The ultrasound diagnostic unit forms an ultrasound image representative of a target object. The storage unit stores training sets in association with respective instructions for operating the ultrasound diagnostic unit. Each of the training sets includes pattern samples associated with a particular action of a user. The image acquisition unit acquires an action of a user to form an action image. The pattern recognition unit recognizes an action pattern from the action image. The control unit retrieves the training sets stored in the storage unit to find a pattern sample having a match with the recognized action pattern. The control unit controls an operation of the ultrasound diagnostic unit based on an instruction associated with the training set including the found pattern sample.
