摘要： An ultrasonic diagnostic apparatus including an ultrasonic probe, and a transmitter/receiver section for scanning a three dimensional region of a detected object with ultrasonic beams by driving the ultrasonic probe and receiving echo signals reflected from an object within the three dimensional region. An organ of the object is detected and three dimensional figure image data depicting a figure of the detected organ in the three dimensional region are formed based on the received echo signals. Also determined from the received echo signals is a function of the detected organ, for example by obtaining and thresholding tissue Doppler image data or harmonic image data, and based on the determined function, three dimensional functional image data depicting the function of the detected organ in the three dimensional region are formed. The three dimensional figure image data are displayed by a wire frame method, a bull's eye map method and/or a semi-transparent surface model method. The displayed three dimensional figure image of the detected organ is combined with display of the functional image of the organ, with neither displayed image obstructing the other displayed image so that the figure image of the organ can be utilized as a positioning guide for selection of the position of the functional image of the organ.

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： A parenchymatous tissue image and a blood vessel image are synthesized as follows. First, a tomographic image of a specific cross section of the parenchymatous tissue image is synthesized with the blood vessel image closer to the viewpoint along the Z-axis than the tomographic image. Then, the resulting image is displayed. Thereafter, the operator inputs specific data from operation unit including a mouse and a keyboard, thereby changing the position of a displayed tomographic image along the Z-axis. This enables the operator to sequentially display two-dimensional tomographic images (B-mode images) constituting a three-dimensional parenchymatous tissue image as if to turn over the pages of a book.

摘要： A three-dimensional imaging method using an ultrasound wave enables a region of interest to be extracted through threshold processing. The method above has its image readily adversely affected and the technique has not yet been too much advanced from the practical viewpoint. By creating an image based on the harmonics components contained in an echo signal it is possible to acquire a high image quality and to advance a practical application of the three-dimensional imaging by the ultrasound wave. The harmonics wave is produced in proportion to sound pressure. That is, the higher the sound pressure, more harmonics components are produced. As a result, the ultrasound beam is effectively narrowed and the spatial resolution is improved. Since the harmonics components are not too much produced from a grating lobe lower in sound pressure than a main lobe, the production of the grating lobe is effectively suppressed, so that an image quality is prominently improved.
摘要翻译：使用超声波的三维成像方法使得能够通过阈值处理提取感兴趣的区域。上述方法的形象容易受到不利影响，从实践的观点来看，该技术还没有太大的进步。通过基于包含在回波信号中的谐波分量来创建图像，可以获得高图像质量并且通过超声波推进三维成像的实际应用。谐波产生与声压成正比。也就是说，声压越高，产生更多的谐波分量。结果，超声波束被有效地变窄并且提高了空间分辨率。由于谐波分量不是由比主波瓣的声压低的光栅产生的太多，所以有效地抑制了光栅的产生，从而显着提高了图像质量。
