摘要： An ultrasonic imaging apparatus comprises an ultrasonic probe, an image-processing part, a received signal intensity-adjusting part, and a display part. The ultrasonic probe three-dimensionally transmits/receives ultrasonic waves. The image-processing part generates a first ultrasonic image along a plane intersecting the scanning lines of ultrasonic waves, based on the signals obtained by transmitting/receiving of the ultrasonic waves. The signal intensity-adjusting part changes the intensity of the signals on the scanning lines passing through a brightness adjustment range for brightness adjustment set on the first ultrasonic image. The image-processing part generates a second ultrasonic image, based on the signal changed by the signal intensity-adjusting part. The display part displays the second ultrasonic image.

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： In time phases except a first time phase, a contour tracking part tracks the position of a region of interest based on image data acquired in each of the time phases. A re-tracking part receives correction of the position of the region of interest in a second time phase, and obtains the position of the corrected region of interest in and after the second time phase based on the image data acquired in and after the second time phase. From position information of the region of interest in and before the second time phase and position information of the corrected region of interest in and after the second time phase, a position calculator obtains position information of the region of interest in all the time phases. A computing part obtains motion information of a tissue within the region of interest based on the position information of the region of interest.

摘要： In the event that images are acquired for multiple cross-sections (multiple phases) by a predetermined imaging mode in an examination under stress to a subject, images of the same phase acquired by the same imaging mode in an examination before stress to the subject is read and simultaneously displayed as reference images together with current images. The operator can bring the cross-sectional position in the examination under stress in correspondence to the position of the examination before stress by comparing the displayed reference images with the current image.
