Abstract:
(EN) Disclosed is a method for acquiring a magnetic resonance image of a target object including a blood vessel by using a 3D gradient echo sequence, the method comprising: a step of acquiring k space data for the target object on the basis of the 3D gradient echo sequence; and a step of acquiring the magnetic resonance image of the target object on the basis of the acquired k space data, wherein the step of acquiring the k space data comprises acquiring the k space data on the basis of the 3D gradient echo sequence having a repetition time (TR) that varies according to at least one of a first axis value and a second axis value in k space of the k space data.
(FR) L'invention concerne un procédé d'acquisition d'une image de résonance magnétique d'un objet cible, notamment d'un vaisseau sanguin, à l'aide d'une séquence d'écho de gradient 3D, le procédé comprenant : une étape d'acquisition de k données spatiales de l'objet cible sur la base de la séquence d'écho de gradient 3D ; et une étape d'acquisition de l'image de résonance magnétique de l'objet cible sur la base des k données spatiales acquises, l'étape d'acquisition des k données spatiales consistant à acquérir les k données spatiales sur la base de la séquence d'écho de gradient 3D ayant un temps de répétition (TR) qui varie en fonction d'une première valeur d'axe et/ou d'une seconde valeur d'axe dans k espaces des k données spatiales.
(KO) 3D 그라디언트 에코(3D gradient echo) 시퀀스를 이용하여 혈관을 포함하는 대상체에 대한 자기 공명 영상을 획득하는 방법에 있어서, 상기 3D 그라디언트 에코 시퀀스에 기초하여 상기 대상체에 대한 k 공간 데이터를 획득하는 단계; 및 상기 획득된 k 공간 데이터에 기초하여 상기 대상체에 대한 상기 자기 공명 영상을 획득하는 단계를 포함하고, 상기 k 공간 데이터를 획득하는 단계는, 상기 k 공간 데이터의 k 공간의 제1 축 및 제2 축 중 적어도 하나의 값에 따라 가변하는 TR(repetition time)을 갖는 상기 3D 그라디언트 에코 시퀀스에 기초하여 상기 k 공간 데이터를 획득하는, 자기 공명 영상을 획득하는 방법을 개시한다.
