求教mri dicom图片问题

pikachu

读入格式为dcm的MRI图像，
其中的dicominfo中的一段为：
Private_0051_10xx_Creator: 'SIEMENS MR HEADER'
                    Private_0051_1008: 'IMAGE NUM 4'
                    Private_0051_1009: '1.0'
                    Private_0051_100a: 'TA 01.27*3'
                    Private_0051_100b: '256*512 I'
                    Private_0051_100c: 'FoV 280*280'
                    Private_0051_100d: 'SP  0.0'
                    Private_0051_100e: 'Tra'
                    Private_0051_100f: 'PH1-8'
                    Private_0051_1012: 'TP 0'
                    Private_0051_1013: '+LPH'
                    Private_0051_1015: 'E'
                    Private_0051_1016: 'M/ND'
                    Private_0051_1017: 'SL 10.0'
                    Private_0051_1019: 'A1'
这个是什么意思，尤其是Private_0051_100e: 'Tra'，有的图片为tra>cor(-12.3)>sag(-0.9)
cor>sag(-6.4)>tra(0.0)
sag>cor(5.8)>tra(0.4)，这些都代表什么，我重点是想知道如何从dicominfo中得知图像的矢状位，冠壮位，横断位等
