摘要： There is disclosed an ultrasonic diagnosis apparatus comprising a transmission/reception unit, a signal processing unit, a conversion unit, and a display unit. The transmission/reception unit transmits/receives ultrasonic waves to/from an object to be examined, thereby obtaining ultrasonic reception signals. The signal processing unit executes signal processing of the ultrasonic reception signals to obtain ultrasonic images. The conversion unit converts an ultrasonic image having a predetermined dynamic image obtained from the object to be examined to which a contrast medium is injected into an ultrasonic image having a dynamic range corresponding to that of the display unit. The display unit displays the ultrasonic image obtained by the conversion unit.

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： The ultrasonic diagnostic system estimates a desired time phase or one cycle period of a moving region (e.g., a heart) that repeats contraction and relaxation cyclically and which can be specified by a presystole, an end systole, a prediastole, an end diastole, and other clinical characteristics for one cycle of the moving region on the basis of the velocity information on multiple positions of the moving region which is obtained for each time phase. More specifically, assuming that, for example, the end systole phase=a time phase in which the myocardial velocity comes to zero or close to zero, the system calculates |myocardial velocity| for each time phase in a predetermined period, and estimates a time phase in which this value comes closest to zero as an end systole phase.

摘要： In the case where a tracking process of a moving tissue performing a contraction movement and an expansion movement and represented by a cardiac wall is performed for one heartbeat from the ED1 to the ED2, a contour position (tracking point) initially set at the ES (End-Systole) is tracked until ED1 in accordance with movement information, the tracking point is rearranged and a position of a middle layer is set at the ED (End-Diastole), the rearranged tracking point including the position of the middle layer is tracked in accordance with the movement information already obtained, and then the tracking point is further tracked in the normal direction until the ED2. Alternatively, an initial reverse tracking process is performed from the ES to the ED1 by using plural middle layer path candidates, and a path passing through the tracking point existing on the middle layer or contours of inner and outer layers and rearranged at the ED1 is searched, thereby accurately creating and evaluating movement information of each of an endocardium and an epicardium of a cardiac wall.

摘要： An ultrasonic diagnostic apparatus capable of measuring a three-dimensional motion of a biological tissue in a short time. An image processor creates volume data based on image data of a B-mode image of a biological tissue and creates image data of a series of tomographic images in time series for the respective two or more sectional positions based on the volume data. A controller displays one tomographic image for each sectional position on a display part. A user operates an operation part to designate a measurement image region on the displayed tomographic image. A displacement calculating part calculates a displacement in time series of the designated measurement image region for each sectional position. A motion information calculating part calculates motion information of the biological tissue based on the displacement of the measurement image region calculated for each sectional position.

摘要： A contour specifying part receives volume data representing a subject acquired by transmission of ultrasonic waves to the subject, and specifies a 3-dimensional contour of a myocardium based on the volume data. A forming part sets a reference point on the contour of the myocardium, and forms an image generation plane including a plane substantially orthogonal to the contour of the myocardium at the reference point. An image generator generates image data on the image generation plane based on the volume data. A display controller controls a display to display an image based on the image data.
