摘要: An ultrasonic Doppler diagnosis device having a velocity data interpolating section for generating interpolated velocity data for interpolating velocity data between two sound lines and two scanning lines, using the velocity data at the intersections. The velocity data interpolating section converts two scalar arrays of unsigned numeric data corresponding to a first and second numeric values to signed arrays of numeric data using a data converting section and generates the interpolated velocity data based on the converted signed array of numeric data, when a result of identification obtained from an identifying section indicates that one of the first and second numeric values has a positive velocity smaller than a first threshold value corresponding to a positive velocity, and the other of the first and second numeric values has a negative velocity greater than a second threshold value corresponding to a negative velocity.

摘要: An ultrasound observation apparatus has an ultrasound probe or an ultrasound endoscope manually moved relative to a subject, and displays a plurality of ultrasound tomographic images in time sequence with the movement. The ultrasound observation apparatus has a control section which, when a first display range is selected, performs control so that images are displayed in a first number of displayed frames per stroke time, which, when a second display range is selected, performs control so that the number of displayed frames per stroke time is smaller than the first number of displayed frames, and which, when a manual scanning mode is selected, performs control so that a predetermined number of frames per stroke time are displayed regardless of whether the display range is the first display range or the second display range.

摘要: First to third interpolation processing circuits are configured by a data identifying unit, a data converting unit, a data interpolating unit, a data reconverting unit and four switches SW1 to SW4. After the data identifying unit determines a value of velocity data, the data converting unit, the data interpolating unit and the data reconverting unit switch between vector operation on a complex space based on a scalar array and vector operation on a complex space based on a color palette array and execute interpolation processing.
