Title (EN) BEAM FOCUSING METHOD ON BASIS OF LOCAL ESTIMATION OF TISSUE ATTENUATION VALUE
(FR) PROCÉDÉ DE FOCALISATION DE FAISCEAU SUR LA BASE D'UNE ESTIMATION LOCALE DE VALEUR D'ATTÉNUATION DE TISSU
(KO) 조직 감쇄 값의 로컬 측정에 기반한 빔집속 방법
Abstract: front page image
(EN)The present invention relates to a beam focusing method comprising the steps of: obtaining a beam focus image signal by means of an initial acoustic velocity; estimating an attenuation value by means of the obtained image signal; identifying a local area by means of the estimated attenuation value; and obtaining a beam focus image signal by means of an acoustic velocity in accordance with the identified local area. Therefore, attenuation information is analyzed and evaluated and then beam focusing is performed by means of applying a more accurate acoustic velocity for a tissue corresponding to the attenuation information, and thus diagnostic image information comprising an image signal having improved resolution can be provided.
(FR)La présente invention concerne un procédé de focalisation de faisceau comprenant les étapes de : obtention d'un signal d'image de focalisation de faisceau au moyen d'une vitesse acoustique initiale; estimation d'une valeur d'atténuation au moyen du signal d'image obtenu; identification d'une zone locale au moyen de la valeur d'atténuation estimée; et obtention d'un signal d'image de focalisation de faisceau au moyen d'une vitesse acoustique conformément à la zone locale identifiée. Par conséquent, des informations d'atténuation sont analysées et évaluées et ensuite, une focalisation de faisceau est effectuée par application d'une vitesse acoustique plus précise pour un tissu correspondant aux informations d'atténuation et, par conséquent, des informations d'image diagnostiques comprenant un signal d'image ayant une résolution améliorée peuvent être fournies.
