An ultrasound imaging apparatus and a controlling method thereof are provided. The ultrasound imaging apparatus acquires a plurality of ultrasound contrast agent images of a region of interest of the object after an ultrasound signal for destroying a contrast agent is transmitted to the region of interest of the object, into which the contrast agent is injected, at time intervals of t(k 1, 2, ..., n, and n is an integer of 2 or more), generates a kcumulative ultrasound contrast agent image by accumulating the acquired ultrasound contrast agent images at every time intervals of tto generate n cumulative ultrasound contrast agent images, and displays the generated n cumulative ultrasound contrast agent images, wherein tsatisfies t> t.

Provided are an ultrasound diagnosis apparatus for determining abnormality of a fetal heart, and an operating method thereof. The ultrasound diagnosis apparatus detects the position of a heart in an ultrasound image of a heart of a fetus and determines abnormality of the heart of the fetus based on the detected position of the heart.

Provided are a method of displaying a Doppler image and an ultrasound diagnosis apparatus for performing the method. The method includes: obtaining a first Doppler signal where clutter filtering corresponding to each of a plurality of pixels is not performed and a second Doppler signal where clutter filtering corresponding to each of the plurality of pixels is performed; determining a first motion score indicating a degree of flash artifact occurrence by using velocity information of the first Doppler signal; determining a first weight for suppressing flash artifacts of each pixel based on the first motion score and a velocity difference value between the first Doppler signal and the second Doppler signal; generating a first Doppler image of the object by applying the first weight to the second Doppler signal of each pixel; and displaying the first Doppler image of the object.

An ultrasonic imaging apparatus and a method for controlling the same are disclosed. The ultrasonic imaging apparatus includes: an ultrasonic probe configured to acquire a plurality of shear wave data segments from a target object; a controller configured to determine at least one shear wave data group by grouping the plurality of shear wave data segments according to a predetermined condition; and a display configured to display at least one image corresponding to the at least one shear wave data group, and display the plurality of shear wave data segments at positions different from a specific position at which the image is displayed.

A probe of an ultrasonic imaging apparatus and a method for manufacturing the same are disclosed. The probe for an ultrasonic imaging apparatus includes a piezoelectric unit including a piezoelectric substance and an electrode; a printed circuit board (PCB) unit having a printed circuit board (PCB), configured to be formed at a lateral surface of the piezoelectric unit; a matching layer formed at front surfaces of the piezoelectric unit and the PCB unit; and a backing layer formed at a back surface of the piezoelectric unit and the PCB unit. The probe and a method for manufacturing the probe can reduce a variation of ultrasonic acoustic characteristics caused by a printed circuit board (PCB) because the PCB is not arranged among a piezoelectric substance, a matching layer, and a backing layer. A PCB is provided at a lateral surface of the piezoelectric substance, so that strength against impact can be increased either during channel division based on dicing or during the usage time of a probe. In addition, a single crystal (monocrystal) may be used as a piezoelectric substance or the like, such that a probe having a large bandwidth can be formed, and low-frequency ultrasonic signals and high-frequency ultrasonic signals can be transmitted and received. In addition, the probe and the method for manufacturing the same can easily perform channel division of the acoustic module, and make the divided acoustic module using a curvature, and thus can be applied to various technical fields without being limited to the shapes of probes.

Provided are an ultrasound diagnosis apparatus and a method of operating the same, which are capable of providing a guide for improving quality of an ultrasound image according to a relative position between a transducer and an object. The ultrasound diagnosis apparatus includes: a probe configured to transmit ultrasound signals to an object and receive ultrasound echo signals reflected from the object; a display configured to display a state of contact between the object and the probe; and a processor configured to determine, based on the ultrasound echo signals, whether the probe is brought into contact with the object and the state of contact between the object and the probe, and to control the display to display an indicator indicating a result of the determining.
