摘要： PROBLEM TO BE SOLVED: To provide a technology that freely changes the frequency of a reference signal in a digitized ultrasonic diagnosis device employing frequency shift beamforming method and makes it possible to conduct various high-quality or high-speed imaging.
SOLUTION: Reception signals obtained by an ultrasonic element group disposed in an array are digitized in a sampling cycle higher than a Nyquist frequency of the reception signals, and are mixed with reference signal. The mixed signals are then accumulated in a sampling direction, beamformed and added by wave reception focusing means. The reference signal serially are read out to be used from memory means in such a manner as to correspond to the sampling number of the reception signals. A reference signal train acquired from signals, the frequency of which decreases gradually with a lapse of time, from wave transmission, or a reference signal train obtained alternately from two signals having different frequencies, may be stored in advance in memory means.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic imaging device capable of correcting a phase rotation effect and imaging true acoustic impedance change in a living body.
SOLUTION: Ultrasonic wave signals returned from an inspection object to a search unit 1 are converted to electric signals by the search unit 1 and sent through a transmission / reception changeover switch group 5 to a complex reception beam former 20 and dynamic focusing for adjusting a delay time corresponding to the timing of reception is executed. By using the output of the beam former 20 which outputs the beams of a real part and an imaginary part, in a phase rotation correction part 21, phase rotation due to attenuation depending on a frequency is corrected or a phase rotation portion in the azimuth direction of the beam is corrected or both of them are corrected. After the correction of the phase rotation, in an acoustic impedance change amount computing part 22, a derivative relating to the space position of acoustic impedance is obtained, and filtered signals are displayed by an image at a display part 24 through a scanning converter 23.

摘要： PROBLEM TO BE SOLVED: To image delay data corresponding to a speed of an ultrasonic wave to be propagated in a medium by obtaining the speed by a simple calculation. SOLUTION: The ultrasonic wave is trially radiated into an organism in a delay time corresponding to a mean ultrasonic velocity. A delay time error is obtained by a delay time error detector 131a from signals of respective channels obtained by delay controlling its reception signal by a digital delay circuit 8 by calculating. This obtained data is compared with a plurality of delay time error data of the ultrasonic velocity with the ultrasonic velocity previously stored in an ultrasonic velocity corresponding delay time error memory 132 as a parameter by a delay time comparator 133. The ultrasonic velocity in response to the coincident delay time error of the data is elected from an ultrasonic velocity memory 134 by an ultrasonic velocity selector 135. Thus, the ultrasonic velocity in the organism is obtained. The obtained velocity is fed back to a CPU 14. Then, the delay data when ultrasonic scanning is conducted at the examination is supplied to the delay circuit.
