An ultrasound diagnostic apparatus includes the following. A deflection controller generates delay time information to make phases of reception signals input to channels uniform according to a deflection angle. A channel selector selects a channel in which the reception signal is turned on or off so that the phases of the reception signals input to channels are different and which generates channel selection information. A reception delay interrupter provides the delay amount to the reception signal and which turns on or off the reception signal. An adder adds the plurality of reception signals which are provided with the delay amount and turned on.

Ultrasound diagnostic apparatus with electromagnetic noise suppression

An ultrasound diagnostic apparatus that can combine image data and has a first image mode and a second image mode, includes: a hardware processor that sets a scan parameter of an image of a first image mode according to restriction information of the scan parameter, when the second image mode is turned on and generates control information; a transmitter that generates a drive signal and inputs the drive signal to an ultrasound probe that transmits transmission ultrasound to a test object and receives reflected ultrasound; a receiver that generates a reception signal of the images in the first and second image modes from an electric signal generated in the ultrasound probe; a first-image-mode image generator that generates first-image-mode image data; a second-image-mode image generator that generates second-image-mode image data; and a combiner that generates combined image data by combining the generated first-image-mode image data and second-image-mode image data.

Ultrasound diagnostic apparatus, ultrasound diagnostic image generating method, and program

An ultrasound image diagnostic apparatus includes, a transmitter to repeat alternating supply of first pulse signals and second pulse signals to the ultrasound probe, the second pulse signals being generated by polarity inversion of the first pulse signals; a receiver; a memory to store first sound ray data corresponding to the first pulse signals; an adder to add the stored first sound ray data and second sound ray data corresponding to the second pulse signals; a line-signal processor to generate fundamental line data and harmonic line data; a needle emphasizing signal processor to generate needle image data from the generated fundamental image data; a harmonic signal processor to generate harmonic image data; a synthesizer to combine the needle image data and the harmonic image data; and a display controller to display the synthesized image data.

Ultrasound image diagnostic apparatus

An ultrasonic diagnostic apparatus includes: a plurality of vibration elements () that transmit and receive an ultrasonic beam; a plurality of transmission circuits () that are connected to the respective vibration elements and output a transmission driving signal to be used for driving the vibration elements; and a transmission power source () that supplies electric power to the transmission circuits. The ultrasonic diagnostic apparatus further includes: a pulse detection unit () that detects a transmission signal to be used for generating the transmission driving signal; an electric power measurement unit () that detects an amount of electric power supplied to the transmission circuits as a whole; a distribution calculation unit () that calculates an amount of electric power distributed into each of the vibration elements based on outputs of the pulse detection unit and the electric power measurement unit; and a power distribution derivation unit () that derives electric power having been supplied to each of the plurality of vibration elements based on an output of the distribution calculation unit, wherein the transmission driving signal is controlled based on the power distribution derived in the power distribution derivation unit. With this configuration, it is possible to provide a more compact and highly reliable ultrasonic diagnostic apparatus capable of performing a temperature monitoring that detects local heat generation of the vibration elements based on the actual transmission power by using a circuit with a reduced number of components.
