ULTRASOUND SYSTEM AND METHOD FOR PROVIDING ULTRASOUND SPATIAL COMPOUND IMAGE BASED ON MASKS

摘要

PURPOSE: An ultrasound system and a method for offering an ultrasonic wave space compound image based on a mask are provided to enhance picture quality of the ultrasonic wave space compound image by eliminating a seam artifact generating according to the state where an ultrasonic probe is touched with an object using a mask. CONSTITUTION: An ultrasonic wave data acquisition part(110) transmits an ultrasonic signal to an object and receives an echo signal reflected from the object and operates In order to obtain ultrasonic data of scan lines about a plurality frames in which scan lines are steered at a plurality of steering angles. A mask formation part forms masks which correspond to the plurality frames using the ultrasonic data. A video formation part forms a plurality mask images based on the masks and forms a plurality ultrasonic wave images based on the ultrasonic data. A space compound part forms an ultrasonic wave space compound image based on the plurality mask images.
