摘要： Two-dimensional distribution data of velocities on a moving object in an object to be examined is obtained. A motion field which defines the motion direction of a tissue is stored. A plurality of tracking points are obtained in a tissue range in the two-dimensional distribution data. The moving positions of the tracking points are estimated and the positions are sequentially tracked. Velocities toward the motion direction defined by the motion field are obtained on the basis of the two-dimensional distribution data. One intermediate output value is obtained by performing a predetermined computation by using velocities toward the motion direction at tracking positions of at least two tracking points in each time phase. The values of intermediate positions are obtained by performing weighted addition of intermediate outputs at different positions. A display image is generated and displayed by using the values of the intermediate positions.

摘要： An ultrasound diagnostic apparatus having an ultrasound probe, a device for transmitting ultrasound to an subject through the ultrasound probe to receive echoes from the subject, a spectrum processor for approximating a spectrum of each of the echoes to a predetermined shape, and a unit for reconstructing an ultrasound image based on an output of the spectrum processor. The spectrums of the echoes are distorted by various reasons. There is a method for correcting a spectrum by enhancing only a high-frequency component of the echoes. Since this method is no more than to consider one reason, i.e., only frequency dependence of attenuation, a suitable correction cannot be made. According to the present invention, the spectrum is approximated to the predetermined shape, therefore the distortion of the spectrum caused by various reasons can be suitably corrected.

摘要： A reception signal containing phase information and amplitude information is obtained by scanning a cross section of a subject with an ultrasonic wave. An ultrasonic image is formed on the basis of the reception signal and displayed. A noise component is filtered from reception signals at respective points in the cross section. The reception signals, which have not been non-linear processed, i.e., have not been subjected to an image forming process, are filtered. Therefore, the suppression effect of suppressing an image of a portion which moves at a relatively low speed and the emphasis effect of emphasizing an image a portion which moves at a relatively high speed can be improved as compared to the conventional art in which an ultrasonic image after non-linear process is filtered.

摘要： When displaying a plurality of images in different conformations in relation to information of a tissue motion typified by a heart wall motion, support information which is used to rapidly and easily visually confirm a relative positional correspondence relationship between an MPR image, a polar mapping image, and a three-dimensional image is generated and displayed. A marker indicative of a desired local position is set and displayed as required. Further, a position corresponding to the set or changed marker may not be present on the MPR image. In such a case, the MPR image always including a position corresponding to the set or changed marker is generated and displayed by automatically adjusting a position of an MPR cross section.
