  • Publication number: 20200121297
    Abstract: Provided is an ultrasound imaging apparatus including: an ultrasound probe configured to transmit an ultrasound signal to an object and receive an eco-signal from the object; a contrast agent destructor configured to transmit acoustic energy for destructing the contrast agent introduced into the object; and a controller configured to acquire a first image including a contrast agent signal and a tissue signal on the basis of the received echo signal before the destruction of the contrast agent introduced into the object, acquire a second image including the tissue signal on the basis of the echo signal after the destruction of the contrast agent introduced into the object, and generate a third image on the basis of a subtraction between the first image and the second image.

  • Publication number: 20190247023
    Abstract: 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 tk (k?1, 2, . . . , n, and n is an integer of 2 or more), generates a kth cumulative ultrasound contrast agent image by accumulating the acquired ultrasound contrast agent images at every time intervals of tk to generate n cumulative ultrasound contrast agent images, and displays the generated n cumulative ultrasound contrast agent images, wherein tk satisfies tk>tk?1.

  • Patent number: 9629610
    Abstract: An ultrasound diagnosis apparatus providing a map of an interest index. The ultrasound diagnosis apparatus includes: a calculating unit for calculating a mechanical index (MI) corresponding to a depth value in a direction in which ultrasound travels from an ultrasound output part of a transmission transducer; a visualization unit for generating an MI map in which a relationship between the calculated MI and the depth value is visualized in the form of a graph; and a display unit for displaying the MI map.

  • Patent number: 9295452
    Abstract: A method of correcting ultrasound images, the method including the operations of, by an ultrasound output unit, outputting an ultrasound signal to a target object; obtaining an mechanical index (MI) map indicating a correlation between depth values according to a travel direction of the ultrasound signal, and MI values by the ultrasound signal; and adjusting a gain value of an ultrasound echo signal corresponding to the ultrasound signal by using a reverse MI map that is obtained by reversing the MI map, so as to allow the MI values, which are displayed on the MI map, to be a virtually constant MI value with respect to the depth values.
