摘要： An ultrasonic diagnosis apparatus comprises a probe having a plurality of transducers for performing transmission/reception of ultrasonic waves; a selection circuit for sequentially selecting the transducers for performing transmission/reception of ultrasonic waves; and an A/D converter for converting a reception waveform signal from the transducer selected by the selection circuit into a digital waveform signal. The apparatus also includes a memory for storing the digital waveform signal converted by the A/D converter in correspondence with the selected transducer; and a read control circuit having a wavefront locus address generator for generating a wavefront locus data corresponding to time-of-flight data between each point in an ultrasonic scanning region and respective transducers to synthesize a wavefront converging on a point in the ultrasonic scanning region (including points which are not located on lines normal to the radiating surfaces of the transducers). The apparatus also includes an output unit for outputting the wavefront locus data to the memory as a read address in order to read waveform samples along the wavefront; and a synthesis circuit for synthesizing the waveform samples read from the memory by a read address from the read control circuit.

摘要： The ultrasonic diagnosing apparatus including an ultrasonic probe, an ultrasonic wave transmitting and receiving unit for transmitting ultrasonic pulses toward a living body and receiving ultrasonic waves reflected by the living body to produce an echo signal, and a signal processing circuit for processing the echo signal such that a Doppler frequency representing a relative movement between the ultrasonic probe and living tissues is detected and a velocity of a blood stream which is free from the influence of the relative movement is detected on the basis of the Doppler frequency due to the relative movement between the ultrasonic probe and the living tissues. In a power spectrum distribution, the Doppler frequency can be detected as a peak frequency at which the magnitude of the power spectrum becomes maximum. In one embodiment of the ultrasonic diagnosing apparatus, the frequency axis of the power distribution is shifted such that the Doppler frequency becomes zero, and finally a Doppler frequency due to the blood stream is detected from a power spectrum component outside a cut-off frequency range. In a second embodiment, a first Doppler frequency due to the blood stream is detected from a signal component which is obtained by MTI filters and auto-correlation circuits, a second Doppler frequency due to the relative movement between the ultrasonic probe and the living tissues is detected from a signal component which is obtained by the auto-correlation circuits, and then a velocity of the blood stream is detected from a difference between the first and second Doppler frequencies.

摘要： An ultrasonic image analyzing apparatus determines, on the basis of ultrasonic tomographic image information on a body portion being inspected, the properties of the tissues of the inspected portion, and causes a lesion portion to be displayed on a color image screen or the like, thereby allowing a diagnosis. The apparatus enables appropriate parameters for image analysis which correspond to the object organ, a body mark, and the type of ultrasonic probe used, to be automatically set. The apparatus also enables the size, the shape, the manner of scanning, etc. of regions of interest (ROIs), which are provided on the image of the portion being observed for the purpose of calculating the parameters, to be set in correspondence with the directions in which the ultrasonic wave from the probe propagates. Accordingly, the apparatus makes it possible to perform optimal image analysis with respect to the observation-object portion, and hence, perform correct diagnosis.
