the field of the PixelData is empty, how to get HU?

Post by SoftwareLab » Mon Apr 18, 2011 3:02 pm

Hi Everyone,

Need some infos about how to get HU values.

As far as I know, it´s calculated as follows:
HU=PixelData * rescale slope + intercept value

In the header file, the field of the PixelData is empty, so what
should I do to get the HU ?

Here is a part of the header, it may be of interest:

0028-0002 SamplesPerPixel US 1
0028-0010 Rows US 512
0028-0011 Columns US 512
0028-0030 PixelSpacing DS 0.923\0.923
0028-0100 BitsAllocated US 16
0028-0101 BitsStored US 16
0028-0102 HighBit US 15
0028-0103 PixelRepresentation US 1
0028-1050 WindowCenter DS 50
0028-1051 WindowWidth DS 350
0028-1052 RescaleIntercept DS 0
0028-1053 RescaleSlope DS 1

7FE0-0010 PixelData OW ----



Any suggestions ??
Thanks in advance.
