Abstract

An ultrasonic diagnostic system includes a probe composed of a group of transducers for transmitting and receiving an ultrasonic wave, a main system connected with the probe by a cable, a memory card, and a battery pack for supplying power. The ultrasonic diagnostic system further includes a data processing unit and a monitor which are provided separately from the above components. The probe and main system are prepared for each ultrasonic scanning mode. The data processing unit subjects the received signal data recorded in the memory card to sophisticated data processing which cannot be carried out by the main system thereby to display the processing result. An examiner can carry the probe, main system, memory card and the battery pack for supplying power instead of a stethoscope to acquires diagnosis data and can process a suspicious image in diagnosis at bedside or house call using the data processing unit thereby to implement precise diagnosis.
