Abstract: An ultrasound diagnostic device including a transmitter, a first image processor, a second image processor, and an image synthesizer. The transmitter alternates between first transmission events that include transmission of first detection waves and second transmission events that include transmission of second detection waves. The first image processor generates frames of first images based on reception signals corresponding to a plurality of the first transmission events. The second image processor generates frames of second images based on reception signals corresponding to the second transmission events. The image synthesizer superimposes the second images on the first images to generate synthesized images. Frame rate of the second images is higher than that of the first images. The transmitter performs a third transmission event prior to the second transmission events that includes transmission of a plurality of the first detection waves to acquire reception signals corresponding to one frame of the first images.

Abstract: An ultrasound diagnostic device generates a frame reception signal by compounding sub-frame reception signals acquired from a subject body through an ultrasound probe. The sub-frame reception signals are generated through sub-scans composing an ultrasound scan. Between the sub-scans, a range in the scanned subject body differs due to a different ultrasound beam steering angle used. The diagnostic device includes a control circuit with a reception signal acquirer acquiring sub-frame reception signals, and a map creator creating sub-frame enhancement maps corresponding to the sub-frame reception signals, the maps created by calculating, for a pixel region reception signal, an enhancement amount according to a characteristic value calculated based on the pixel region reception signal. The diagnostic device also includes an enhancement-applied reception signal generator generating an enhancement-applied frame reception signal by compounding pixel region reception signals considering the enhancement amount included in at least one sub-frame enhancement map.

Abstract: An ultrasound diagnosis apparatus generates an ultrasound image of an inside of a subject on a basis of ultrasound signals which are reflected off at the inside of the subject and received. The apparatus includes a needle position specifier and a needle emphasis processor. With respect to each region in the ultrasound image, the needle position specifier obtains a deep region feature value relating to signal intensity in a region deeper than a region subject to judgment in relation to ultrasound signal distribution along an emission direction of an ultrasound emitted in a subject, and specifies a position of a puncture-needle which is inserted in the subject. The needle emphasis processor carries out a process for emphasizing the position of the puncture-needle which is specified in the ultrasound image.
