Abstract: PROBLEM TO BE SOLVED: To house an ultrasonic device in a single portable unit by housing an array converter, a transceiver circuit and a beam forming device within a housing container so as to miniaturize the ultrasonic device. SOLUTION: Call originating/receiving ASIC 20 within the housing container controls the call-originating/receiving opening of a converter array 10 and the gain of a receiving echo signal, transfers a received echo to a front end ASIC 30 and beam-forms an echo from individual converter elements to a scanning line signal, and a storage device 32 stores data used by the beam forming device. The beam-formed scanning line signal is transferred to a digital signal processing ASIC 40 to transfer obtained ultrasonic B mode and doppler information to a back end ASIC 50. ASIC 50 is connected to a data port set as an infrared transmitter or a PCMCIA interface 56 to connect another module and function to the ultrasonic unit.
