摘要： An ultrasonic wave transmitting and receiving apparatus includes a control pulse generator for sequentially generating control pulses from its output terminals with a cyclically varied delay time. The control pulses are controlled in such a delay time relation as to enable the beams of ultrasonic waves to be deflected in left and right directions. The output pulse signals of deflection control units are controlled in such a delay time relation as to permit the beams of ultrasonic waves to be brought into focus by electron focussing control units. By the output pulses of the electron focussing control units, drive pulse generators are driven to supply drive pulses to electroacoustic conversion elements for generating the above-mentioned beams of ultrasonic waves. Some of the ultrasonic waves radiated in a medium is reflected at a boundary between two objects different in physical property (acoustic impedance) from each other and converted through the electroacoustic conversion elements to electric signals. The reflection wave signals so converted are sequentially stored in memory units, the contents of which are read out in response to the output pulse signals of the electronic focussing control units. The readout signals are, after being added together, supplied to a cathode ray tube.

摘要： In an ultrasound diagnosis apparatus, a plurality of transducers arranged in an ultrasound probe are classified into two transducer groups. By using a parallel simultaneous reception method, ultrasound beams from an observation point of an object to be examined along a transmitting direction of an ultrasound beam are received by the transducer groups. In other words, echo signals from different directions at the observation point are received. Flow velocities are respectively calculated on the basis of the echo signals received by the transducer groups, and the calculated flow velocities are added and averaged.

摘要： In an ultrasonic imaging apparatus, ultrasound beams are diffused in the slice direction perpendicular to the scanning direction to thereby scan a three-dimensional region of a subject under examination with wide ultrasound beams. Thus, echoes are detected accumulated in the slice direction. Echoes from the surface of a region of interest, such as a fetus, are stronger than echoes from within the region of interest. As a consequence, an ultrasonic image is produced which approximates a surface image. The amount of data required to produce an ultrasonic image, the ultrasonic beam scanning procedure, and the signal processing system are the same as before, which permits real-time operation. A conventional ultrasonic imaging apparatus can be used without modification except a probe adapter for diffusing ultrasound beams in the slice direction.

摘要： A measuring apparatus for an ultrasonic velocity in a region of interest within a medium includes an array transducer, and a velocity measuring circuit. The transducer is constructed of a plurality of transducer elements which are subdivided into at least first and second transmitting sections and first and second receiving sections with having a distance. First and second ultrasonic beams are emitted from the first and second transmitting sections to the ROI under the condition that the transmitting beam axis is intersected by the receiving ultrasonic beam axis. Then, the first and second receiver sections receives in total four echoes reflected from four corners of the ROI. The velocity measuring circuit calculates the propagation time of the ultrasonic beams and finally the ultrasonic velocity based upon the propagation time.

摘要： In an ultrasonic diagnostic apparatus using an array type transducer probe, wherein improved tomographic image resolution is desired by electronically focusing ultrasonic wave toward an object to be examined in both directions, i.e., the array direction and the lens direction. During first scanning of the ultrasonic transducer array in the array direction, the signals received from the probe are synthesized in phase with respect to each other via delay lines having predetermined delay times to obtain first scanned signals in real time, so that focusing the reflected ultrasonic wave can be electronically accomplished in the array direction. After this first scanning, the probe is mechanically moved to a given position in the lens direction normal to the array direction. Then a second scanning operation is accomplished to obtain similar first scanned signals. All of the first scanned signals are processed by a delay time control circuit, digitized, and then stored. Finally, all of the stored first scanned signals are read out and synthesized in phase with respect to each other by an adder circuit to obtain second scanned signals, so that focusing the reflected ultrasonic wave can be accomplished in the lens direction. The resultant second scanned signals are converted into analogue signals to be displayed as a tomographic image of the desired diagnostic part in the object.
