Aspects of present disclosure relates to ultrasonic diagnostic systems. In certain embodiments, ultrasonic diagnostic system includes: a local host in a first location, a mobile information and control terminal, a remote host connected to an ultrasonic diagnostic imaging system in a second location, and a communication network. The mobile information and control terminal is operated by an ultrasonic diagnostic expert located in the first location. The mobile information and control terminal retrieves patient information of a patient from patient databases, provides ultrasonic diagnostic control instructions from ultrasonic diagnostic expert to ultrasonic diagnostic technicians in second location. An ultrasonic diagnostic technician performs ultrasonic diagnostic examination on patient according to the ultrasonic diagnostic control instructions and transmits patient ultrasonic diagnosis information back to the local host and the ultrasonic diagnostic expert in real time. The ultrasonic diagnostic expert then generates and displays the ultrasonic diagnosis reports of the patient.
