Abstract: In an ultrasonic imaging device having an image synthesizing unit, correlation between images to be synthesized is computed for balancing between an improvement in contrast resolution and an improvement in spatial resolution, and an amount of displacement between the images is computed. When the amount of displacement is large, the signals after envelop detection are synthesized. When the amount of displacement is small, RF signals are synthesized. Alternatively, the mixing frequency may be variable according to the amount of displacement, and the balance between an improvement in spatial resolution and that in contract resolution is achieved according to a degree of the positional displacement.

Abstract: A one frame image of a moving image formed by producing tomographic images of an object to be examined is displayed (S2), a mark is superposed on a designated portion of a tissue the movement of which is tracked in the displayed one frame image (S3), a cutout image of a size including the designated portion is set in the one frame image (S4), local images are searched in another frame images of the moving image and a local image of the identical size which is most coincided with the cutout image is extracted (S5,6), and a coordinate of the designated portion after movement is calculated based on a coordinate difference between the most coincided local image and the cutout image (S7), thereby the movement of tissue is quantitatively measured.

Abstract: An ultrasonic diagnostic apparatus transmits an ultrasonic beam into an object to be examined using a multi-ring arrangement formed with transducer elements arrayed two-dimensionally in concentric rings and receives an echo so as to create a tomogram or a three-dimensional image of the object. To correct for focusing error due to the difference in length of ultrasound propagating paths, the ultrasonic diagnostic apparatus groups the transducer elements so as to form a multi-ring arrangement, transmits/receives ultrasonic beams with a delay to each ring of the multi-ring arrangement and scans the ultrasonic beam so as to create an ultrasonic image, measures delay error due to presence of a sound speed non-uniformity portion of the object and changes either the coupling of the multi-ring or the delay time based on the measurement error.

The calculated sonic velocity is fed back to CPU, and the delay data on the delay applied in the ultrasonic scanning is provided to a delay circuit.

Abstract: An ultrasonic diagnostic apparatus acquires images different in a frequency. The invention is composed of a transducer including plural elements for sending an ultrasonic wave and receiving the reflected ultrasonic wave, analog to digital converters that digitize plural received signals, first mixers that respectively multiply a signal from the converter and a first digital reference signal, first filters that respectively extract a signal having a predetermined center frequency from a signal from each first mixer, digital delay units that respectively delay a signal from each first filter, an adder that adds plural signals from the digital delay units, and a second mixer that multiplies a signal from the adder and a second digital reference signal. An envelope detector detects a signal from the second mixer, and a scan converter converts a signal from the detector to a picture signal for display, so the pass band of the filter is not required to be changed.
