Abstract: An ultrasound diagnostic apparatus includes an ultrasound probe and an imaging unit that transmits and receives an ultrasound beam to and from a subject using the ultrasound probe and converts a received signal output from the ultrasound probe into an image to generate an ultrasound image of the subject, according to set imaging conditions. The ultrasound diagnostic apparatus further includes a probe state determination unit that determines whether the ultrasound probe is in an aerial emission state or a contact state with the subject; and an apparatus control unit that changes the imaging conditions in a case in which the probe state determination unit determines that the ultrasound probe has been changed from the contact state with the subject to the aerial emission state and controls the imaging unit such that the ultrasound image is generated using the changed imaging conditions.

Abstract: A photoacoustic image evaluation apparatus includes a processor configured to acquire a first photoacoustic image generated at a first point in time and a second photoacoustic image generated at a second point in time before the first point in time, the first and second photoacoustic images being photoacoustic images generated by detecting photoacoustic waves generated inside a subject, who has been subjected to blood vessel regeneration treatment, by emission of light into the subject; acquire a blood vessel regeneration index, which indicates a state of a blood vessel by the regeneration treatment, based on a difference between a blood vessel included in the first photoacoustic image and a blood vessel included in the second photoacoustic image; and display the blood vessel regeneration index on a display.

Abstract: An acoustic wave diagnostic apparatus and control method processing for transmitting an ultrasound pulse converging on a focusing position in the same direction of a subject from acoustic wave transducers to be driven, among a plurality of ultrasound transducers included in an ultrasound probe, while sequentially updating the acoustic wave transducers to be driven is performed multiple times for the same ultrasound transducers. An acoustic wave echo signal group is obtained by receiving an ultrasound echo of an observation target position in the ultrasound transducers. An autocorrelation operation is performed on a signal, which is obtained by correcting the positional deviation of an acoustic wave echo signal group based on the positional deviation between the focusing position and the observation target position, and an ultrasound echo signal without positional deviation, and a Doppler shift signal indicating the speed of the observation target position is generated.

Abstract: Periodic displacement occurs in body tissue due to heartbeat. A peak level D of the movement distance of the body tissue is detected (Step 21), and a heartbeat cycle T is calculated from a frequency spectrum (Steps 22 and 23). By dividing twice the peak level D by the heartbeat cycle T, the moving velocity of the body tissue in a unit heartbeat cycle is calculated (Step 24). By dividing the moving velocity by a frame rate r, an average movement distance of the body tissue between frames is calculated (Step 25). In a case where the average movement distance is smaller than a predetermined threshold value, a time interval between the frames used for the calculation of the movement distance is extended (being Step 26 NO, Step 27).

Abstract: It is possible to allow image processing on a radiation image such that the same effect of scattered radiation elimination as when imaging is actually performed using a grid is obtained. When performing processing for eliminating scattered radiation included in radiation transmitted through a subject M on a radiation image imaged by irradiating the subject M with radiation, a characteristic acquisition unit 32 acquires a virtual grid characteristic as a characteristic of a virtual grid assumed to be used to eliminate scattered radiation at the time of imaging of the radiation image. A scattered radiation elimination unit 36 performs scattered radiation elimination processing of the radiation image based on the virtual grid characteristic.
