Ultrasound diagnostic apparatus and operation method of ultrasound diagnostic apparatus by determining depolarization to necessitate supply of polarization voltage to ultrasound transducers
An ultrasound transducer unit including a plurality of ultrasound transducers transmits and receives ultrasound waves to and from an inside of a subject. In a case where a checking operation unit is operated, a controller controls a driving voltage supply unit such that a driving voltage is supplied with all of the plurality of ultrasound transducers as driving target transducers. In a case where the checking operation unit is operated, a depolarization determination unit calculates, for each ultrasound transducer, a reception sensitivity in a case where an ultrasound wave is received by driving all of the plurality of ultrasound transducers as the driving target transducers, and determines whether or not a depolarization determination value calculated from the reception sensitivity of each ultrasound transducer satisfies numerical conditions. If the numerical conditions are satisfied, a polarization voltage supply unit supplies a polarization voltage to each of the plurality of ultrasound transducers.
Ultrasound diagnosis apparatus, storage medium, and method for setting of attenuation correction
An ultrasound diagnosis apparatus includes: a hardware processor which performs control of causing a display to display an ultrasound image subjected to attenuation correction, based on a received signal and setting of the attenuation correction, the attenuation correction correcting strength of the received signal lowered due to attenuation of ultrasound waves inside a subject based on a correction amount according to a reflection depth of the ultrasound waves inside the subject; and an input receiver which receives an input operation that designates an adjustment amount, wherein the hardware processor changes the setting of the attenuation correction based on the adjustment amount, and in the changing the setting of the attenuation correction, sets the correction amount, for each of different reflection depths, to an amount according to a product of the adjustment amount and a predetermined weighting factor, the predetermined weighting factor being set correspondingly to each of the reflection depths.
Ultrasound imaging system with depth-dependent transmit focus
An ultrasound system includes a transducer array having three or more rows of transducer elements extending in the azimuth dimension and located adjacent to each other in the elevation dimension. The rows have different mechanical foci in the elevation dimension, with an inner row elevationally focused in the near field and outer rows elevationally focused in the far field. When the user is imaging a subject in the near field, the system beamformer transmits with the inner row with a near field elevation focus. When imaging in the far field a plurality of rows elevationally focused in the far field are used for transmission. When the user is imaging in the mid-range, the beamformer uses both the inner row and the plurality of outer rows to provide an extended mid-range elevation focus.

Ultrasound diagnostic system and method of controlling ultrasound diagnostic system
In an ultrasound diagnostic system, in a case where a routine test in which a plurality of parts of a subject are sequentially subjected to ultrasound diagnosis in accordance with a determined procedure is performed and in a case where information on the subject is input from an input unit, a workstation-side control unit makes a workstation-side display unit perform a second display in which one past image and a current image including an ultrasound image newly created in an ultrasound diagnostic device with respect to a part corresponding to the one past image are displayed side by side on a past image region and a current image region adjacent to each other, in an arrangement order of a plurality of past images in a past routine test of the subject stored in the storage unit.
Control device, control method, control system, and non-transitory recording medium for superimpose display
A control device acquires a plurality of images including an ultrasound image and a photoacoustic image taken in an examination, selects a first image and a second image to be displayed superimposed on the first image, based on information relating to the examination, and generates an object for outputting at least information for displaying the second image superimposed on the first image to an external device.
