  • Patent number: 10736610
    Abstract: Various types of sub-preset conditions corresponding to a selected mother preset condition are read out from a preset condition storage unit which stores at least a plurality of mother preset conditions set concerning image data acquisition conditions and various types of sub-preset conditions set by updating all or some of the image data acquisition conditions included in each of the mother preset conditions. A sub-preset condition suitable for ultrasonic examination on the object is selected from the readout various types of sub-preset conditions. An image data acquisition condition is initialized based on the selected mother preset condition with respect to each unit related to generation of the image data. The image data acquisition condition is updated by using the selected sub-preset condition. Image data is generated based on a reception signal in ultrasonic transmission/reception using the updated image data acquisition condition.

  • Patent number: 7749167
    Abstract: An ultrasonic diagnosis apparatus and method wherein both imaging of a contrast effect and imaging of a tissue appearance before and after inflow of a contrast medium can be realized on condition that low-power transmission and a high frame rate are maintained. The ultrasonic diagnostic apparatus includes a transmission/reception unit for transmitting subject ultrasonic waves with a band substantially centered at a fundamental frequency and generating a received signal based on an ultrasonic echo from the subject, a harmonic unit for extracting a signal of a harmonic component of the fundamental frequency included in the received signal and extracting a signal of the fundamental component with the band substantially centered the fundamental frequency included in the received signal, and a display unit for generating a display image based on the extracted harmonic and fundamental components.

  • Patent number: 6508766
    Abstract: An ultrasound diagnosis apparatus includes an ultrasound probe and a beam-former configured to scan an object to be examined with ultrasound waves through the ultrasound probe. A B-mode processor generates B-mode image data on the basis of a reception signal output from the beam-former. A power Doppler processor generates power Doppler data on the basis of the reception signal output from the beam-former. The power Doppler data is generated on the basis of the reception signal acquired under transmission conditions that the burst wave number is equal or substantially equal to that for the B-mode data, and the ensemble size is set to one of 2 to 10. The B-mode image data and power Doppler data are partly synthesized.
