摘要： An ultrasonic diagnostic apparatus according to an embodiment includes transmission circuitry, receiving circuitry and extracting circuitry. The transmission circuitry cause an ultrasonic probe to perform three or more times of ultrasonic wave transmissions, an ultrasonic wave to be transmitted including a center frequency component, a phase of the center frequency component being different in each transmission. The receiving circuitry generates three or more reception signals corresponding to a common reception scanning line based on a plurality of reflected wave signals, the plurality of reflected wave signals being obtained through the three or more times of ultrasonic wave transmissions. The extracting circuitry extracts a nonlinear component included in the three or more reception signals by adding up the three or more reception signals after performing a processing including phase rotation processing on two or more reception signals among the three or more reception signals.

摘要： According to one embodiment, a radiation image diagnostic apparatus includes a gantry and image reconstruction circuitry. The gantry images a subject with radiation over a plurality of phases and acquires a plurality of imaging data sets for the plurality of phases. The image reconstruction circuitry executes an iterative reconstruction for the plurality of imaging data set to generate a plurality of reconstruction images for the plurality of phases. The image reconstruction circuitry executes the iterative reconstruction using, as the initial image, the first reconstruction image obtained by executing the iterative reconstruction based on the imaging data set of the first phase, generating a second reconstruction image for the second phase different from the first phase.

摘要： An ultrasonic diagnostic apparatus according to an embodiment includes an ultrasonic probe and processing circuitry. The ultrasonic probe collects reflected wave data in a time series manner from a region of a subject in motion. The processing circuitry generates time-series volume data from the reflected wave data collected by the ultrasonic probe. The processing circuitry calculates at least either of volume information and motion information on a region of interest of the subject by performing processing including tracking using the volume data. The processing circuitry sets one or more feature positions that represent anatomical features in the region of interest. The processing circuitry displays an MPR image that passes through at least one of the feature positions. The processing circuitry outputs at least either of the volume information and the motion information that includes the feature positions as boundaries.

摘要： According to one embodiment, an ultrasonic diagnostic apparatus includes detection circuitry and processing circuitry. The detection circuitry detects a release state of an ultrasonic probe in an active state. The processing circuitry, when the detection circuitry detects the release state of the ultrasonic probe during activation of a control mode of generating a first image based on an output from the ultrasonic probe, displaying a second image different from the first image, and displaying the first image with a predetermined opacity on the second image, perform one of control to display the second image without generating the first image, control to display the second image without displaying the first image while generating the first image, and control to generate the first image, display the second image, and display, on the second image, the first image with an opacity lower than the predetermined opacity.

摘要： The ultrasonic diagnostic apparatus according to the embodiment includes regulator circuitry, transmission circuitry, and control circuitry. The regulator circuitry convert a power supply input in accordance with a driving pulse signal to generate an output signal. The transmission circuitry convert the output signal to a transmission pulse to drive a ultrasonic probe. The control circuitry generate a driving pulse signal to increase the output signal when allowing the transmission circuitry to generate a transmission pulse having a strength and/or a time width equal to or greater than a predetermined value, in comparison to when allowing the transmission circuitry to generate a transmission pulse having a strength and/or a time width equal to or less than the predetermined value.

摘要： A signal processing device according to an embodiment includes adjustment circuitry and processing circuitry. The adjustment circuitry adjusts a received signal based on an echo of an ultrasonic wave transmitted to a subject with gain corresponding to a location at which the echo has been generated. The processing circuitry corrects the received signal that has been adjusted by the adjustment circuitry and calculates an index value relating to attenuation by using the corrected received signal.

摘要： An ultrasound diagnostic apparatus according to one embodiment includes processing circuitry. The processing circuitry acquires local function index values related to a right ventricle. The processing circuitry generates a functional image of the right ventricle representing a distribution of the local function index values, using a medical model diagram of the right ventricle, the medical model diagram being a model diagram in which the right ventricle is developed onto a plane, and in which a blood inlet portion leading into the right ventricle and a blood outflow portion leading out from the right ventricle are plotted to positions that are separated from each other on the external circumference side of the model diagram. The processing circuitry then causes a display to display the functional image of the right ventricle.
