hi all,
I am processing the 3D PD patients brain now . After recon-all running,
the segmentations of the GM and WM is not accurate although the original dat
a is normal.
additionally, when I use the TKSurfer Tools to review the 3D brain,it is rev
erse.
More informations and images as follows:

Hi Bruce,
Sorry for reply late.
The data were provided by a hospital and the input data were 3D
images.Some image informations as followed(eg.PDSub_02):
0008,103E,Series Description=Ax 3D VBM
0008,1090,Manufacturer's Model Name=SIGNA EXCITE
0018,0000,Acquisition Group Length=484
0018,0020,Scanning Sequence=GR
0018,0021,Sequence Variant=SS\SP\SK
0018,0022,Scan Options=FAST.GEMS\EDR.GEMS\FILTERED.GEMS
0018,0023,MR Acquisition Type=3D
0018,0025,Angio Flag=N
0018,0050,Slice Thickness=1
0018,0080,Repetition Time [TR, ms]=7.652
0018,0081,Echo Time [TE, ms]=3.312
0018,0082,Inversion Time=0
0018,0083,Number of Averages=1
0018,0084,Imaging Frequency=127.755675
0018,0085,Imaged Nucleus=1H
0018,0086,Echo Number=
0018,0087,Magnetic Field Strength=3
0018,0088,Spacing Between Slices=1
0018,0091,Echo Train Length=1
0018,0093,Percent Sampling=100
0018,0094,Percent Phase Field View=100
0018,0095,Pixel Bandwidth=97.6562
0018,1020,Software Version=12\LX\MR Software release.12.0.M5A.0819.a
0018,1030,Protocol Name=PDD-YANGWANQUN/4
0018,1310,Acquisition Matrix=0, 256, 228, 0
0018,1312,Phase Encoding Direction=ROW
0018,1314,Flip Angle=13
0018,1315,Variable Flip Angle Flag=N
0028,0010,Rows=512
0028,0011,Columns=512
It comes up in the proper orientation in tkmedit in three orientations
as attachment(eg.coromaland saggital view).
Tanks,
Xiaojun.
