  • Patent number: 10639013
    Abstract: An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.

  • Publication number: 20140187953
    Abstract: In an ultrasound diagnostic apparatus, when a compound image is produced, delay correction is performed on all of ultrasound images (sub frames) to be combined based on sound velocities set for respective segment regions obtained by dividing the subject. Owing to this configuration, the ultrasound diagnostic apparatus can produce a high quality compound image by spatial compounding or frequency compounding without being affected by distortion in images.

  • Publication number: 20140180090
    Abstract: When tissue elasticity of a subject is measured, an ultrasound diagnostic apparatus sets a sound velocity for each of segment regions established by dividing the subject, processes reception signals output by a piezoelectric element array based on the set sound velocities, and performs tissue elasticity measurement based on the reception signals processed based on the set sound velocities. Owing to this configuration, when tissue elasticity of a subject is measured, the ultrasound diagnostic apparatus prevents the accuracy of tissue elasticity measurement from deteriorating due to image distortions.

  • Patent number: 6822757
    Abstract: A first relationship of correspondence from RGB data to colorimetric values is univalently determined by using an sRGB space, i.e., a standard space which is colorimetrically defined, and a second relationship of correspondence from CMYK data to the colorimetric values is determined. After K data among the CMYK data is constrained under a predetermined condition corresponding to saturation and lightness, an inverse relationship of correspondence from the colorimetric values to CMYK data is univalently determined. Further, a forward relationship of correspondence from the RGB data to the CMYK data is determined from the first relationship of correspondence and the inverse relationship of correspondence.
