20150018684 | ULTRASOUND DIAGNOSTIC APPARATUS, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD - An ultrasound diagnostic apparatus according to an embodiment includes an image acquirer, a volume information calculator, a wall motion information calculator, a time change rate calculator, an extremum detector, and an index calculator. The image acquirer acquires ultrasonic image data including data for a left ventricle. The volume information calculator calculates time-series data of volume information of the left ventricle. The wall motion information calculator calculates time-series data of wall motion information of the left ventricle. The time change rate calculator calculates time-series data of the time change rate of volume information (first time-series data) and time-series data of the time change rate of wall motion information (second time-series data). The extremum detector detects extremums in early diastole of the first time-series data and the second time-series data (first extremum and second extremum). The index calculator calculates an index using the first extremum and the second extremum. | 01-15-2015 |
20150038846 | ULTRASOUND DIAGNOSIS APPARATUS, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD - An ultrasonic diagnostic apparatus according to an embodiment includes an image obtaining unit, a contour position obtaining unit, a volume information calculating unit, and a controlling unit. The image obtaining unit obtains a plurality of groups of two-dimensional ultrasound image data each of which is generated by performing ultrasound scans, the ultrasound scans being performed on each of a plurality of predetermined cross-sectional planes, and performed for predetermined time. The contour position obtaining unit obtains, by performing a tracking process over the predetermined time period, time-series data of contour positions, the contour positions being either one of, or both of, a cavity interior and a cavity exterior of a predetermined site. The volume information calculating unit calculates, on a basis of a plurality of the time-series data of contour positions, volume information of the predetermined site. The controlling unit exercises control so as to output the volume information. | 02-05-2015 |
20150094584 | ULTRASOUND DIAGNOSIS APPARATUS AND IMAGE PROCESSING APPARATUS - An ultrasound diagnosis apparatus includes a calculating unit, an obtaining unit, a determining unit, and a controlling unit. By using a plurality of pieces of three-dimensional ultrasound image data in a time series corresponding to a three-dimensional region including a myocardium of a subject, the calculating unit calculates first movement information indicating a movement of the myocardium by tracking a movement of a region of interest that corresponds to the myocardium and that is set in each of the plurality of pieces of three-dimensional image data. The obtaining unit obtains direction information indicating a direction of a myocardial fiber in the myocardium. The determining unit determines second movement information indicating a movement of the myocardium with respect to the direction of the myocardial fiber, on the basis of the first movement information and the direction information. The controlling unit causes a display unit to display the second movement information. | 04-02-2015 |
20150173707 | IMAGE PROCESSING APPARATUS, ULTRASOUND DIAGNOSIS APPARATUS, AND IMAGE PROCESSING METHOD - An image processing apparatus of an embodiment includes a combined image generator and a controller. The combined image generator projects, on three-dimensional data indicating three-dimensional heart function information obtained from a first volume data group obtained by imaging the heart of a subject, a three-dimensional shape of blood vessels nourishing a cardiac muscle included in second volume data obtained by imaging the heart, thereby producing three-dimensional combined data, and produces combined image data in which the three-dimensional combined data is developed on a surface. The controller causes a display unit to display the combined image data. | 06-25-2015 |
20150216509 | ULTRASOUND DIAGNOSIS APPARATUS - An ultrasound diagnosis apparatus includes an ultrasound transducer, an evaluation value acquisition unit, a determination unit, and an output unit.

The output unit outputs information based on a result of determination by the determination unit. | 08-06-2015 |
20150223778 | ULTRASONIC DIAGNOSIS APPARATUS AND IMAGE PROCESSING METHOD - An ultrasonic diagnosis apparatus according to an embodiment includes a controller, a processor, and an image generator. The controller selects at least one transducer element in a reception aperture formed of a transducer element group arranged in a predetermined direction, based on at least a deflection angle of an ultrasonic wave transmitted to a subject. The processor performs processing on at least one reception signal of a plurality of reception signals generated in the reception aperture such that a signal intensity of a reception signal generated in the at least one transducer element selected by the controller is reduced to be lower than a signal intensity of reception signals generated in transducer elements other than the at least one transducer element, to output the reception signal of the reception aperture. The image generator generates ultrasonic image data, based on the reception signal of the reception aperture. | 08-13-2015 |
20150223781 | ULTRASONIC DIAGNOSIS APPARATUS - An ultrasound diagnosis apparatus includes an ultrasound transceiver and a controller. The ultrasound transceiver includes a changer that changes transmission direction of ultrasound waves. The ultrasound transceiver transmits ultrasound waves in a direction set while being inserted in a subject to acquire biological information of an observation site of the subject. The controller obtains a direction toward the observation site based on the biological information, and controls the changer to adjust the transmission direction of ultrasound waves to the direction thus obtained. | 08-13-2015 |
20150223782 | ULTRASOUND DIAGNOSIS APPARATUS - An ultrasound diagnosis apparatus includes an ultrasound transducer and a controller. The ultrasound transducer transmits and receives ultrasound waves while being inserted in a subject to acquire biological information of a predetermined site of the subject. The controller controls the ultrasound transducer to transmit ultrasound waves based on a trigger signal that is set according to conditions of the predetermined site that exhibits periodic motion, or that is obtained according to the conditions. | 08-13-2015 |
