摘要： To reduce the power consumption of the ultrasonic probe, the number of transducers to be driven at any given time is controlled. More specifically, all transducers are driven, whereby the probe transmits the ultrasonic beams to a subject through an acoustic lens provided in front of the probe. When an echo signal reflected from an interior portion of the subject and a multi-echo signal reflected from the acoustic lens are detected, the transducers whose operation is required to obtain a tomographic image of the subject are driven. When only the multi-echo signal is detected, fewer transducers are driven.

摘要： In an ultrasonic imaging apparatus using pulsed Doppler signal, the amplitudes of the reflected echo signals are decreased in accordance with a depth of the body. The echo signals received by the transducer are detected in the phase detectors in such a manner that the echo signals are mixed with the reference signals whose amplitudes vary in accordance with the distances between the portions in the body and the transducer, over which the reflected echo signals are propagated.

摘要： The ultrasonic beam is transmitted a plurality of times in the same direction. The echo signals from an object under examination are detected by a plurality of receiving delay circuits. The raster signals used for ultrasonic tomogram contain two directional components for one directional transmitting beam. The directions of these components are different from that of the transmitting beam. A raster signal processing unit for tomogram is made up of a single system, eliminating the sensitivity difference problem, in the system using a plurality of receiving circuits. The Doppler signal for Doppler imaging has a high frequency resolution since transmitting of the ultrasonic beam is repeated in the same direction.
