    Abstract: Provided are a method and apparatus for processing a magnetic resonance (MR) image of an object including first and second materials on a magnetic resonance imaging (MRI) apparatus by using multi-parameter mapping including applying to the object a plurality of radio frequency (RF) pulses separated by a first repetition time and a second repetition time, the first repetition time and the second repetition time being determined based on the first material and the second material; undersampling first MR signals corresponding to the first material and second MR signals corresponding to the second material in a K-space; and performing matching between the undersampled first and the undersampled second MR signals and a signal model for the multi-parameter mapping to determine attribute values corresponding to the first and the second materials at at least one point in an MR image of the object.

    Abstract translation: 提供了一种用于通过使用多参数映射来处理包括磁共振成像(MRI)装置上的第一和第二材料的物体的磁共振(MR)图像的方法和装置,包括向对象施加多个射频(RF )脉冲,其由第一重复时间和第二重复时间分离,所述第一重复时间和所述第二重复时间基于所述第一材料和所述第二材料确定; 在K空间中对与第一材料相对应的第一MR信号和对应于第二材料的第二MR信号进行欠采样; 以及执行所述欠采样的第一和所述欠采样的第二MR信号之间的匹配以及用于所述多参数映射的信号模型,以在所述对象的MR图像中的至少一个点处确定对应于所述第一和第二材料的属性值。
