摘要： A transmitter transmits ultrasonic waves to an object via an ultrasonic probe. A receiver receives echo signals reflected from the object via the ultrasonic probe. The receiver executes a delaying process on the echo signals in accordance with a plurality of set sound velocities for a delaying process, thereby generating a plurality of reception signals with different set sound velocities. An image generator generates a plurality of image data with the different set sound velocities based on the reception signals with the different set sound velocities. A contrast calculator obtains the contrast of each of the plurality of image data with the different set sound velocities. A selector selects image data with the highest contrast from among the plurality of image data. A display controller controls a display to display an image based on the image data selected by the selector.

摘要： As one illustrative embodiment, a first calculator obtains a first power value, which is the sum of the absolute value of a plurality of data obtained by a plurality of transmissions. A velocity-vector calculating unit obtains the velocity vector based on a plurality of data. A second calculator obtains a second power value, which is the absolute value of the velocity vector. A post-filter processor comprises one or more post-filter processes to determine the power value, and in the one or more post-filter processes, a power value other than the power value used in obtaining the threshold value for determination is selected as the power value at each observation point and the selected power value is determined based on the threshold value for determination.

摘要： In one embodiment, a scanning unit repeatedly scans an internal region of an object with an ultrasonic wave at a predetermined frame rate via an ultrasonic probe. An image generation unit extracts a blood flow signal based on a Doppler effect from a reflection signal and repeatedly generates a blood flow image representing a spatial distribution associated with power of the blood flow signal at the frame rate. A power average value associated with a frame or local region is calculated for the blood flow image. The blood flow image is corrected. In the correcting, a gain on the power values in the frame or local region in which the power average value exceeds the threshold are substantially reduced, and power values in the frame or local region in which the power average value is not more than the threshold are maintained.
