Purpose¶
Decoding of vendor specific DICOM tags. Until now, only gradients of Siemens, Philips (only multiframe) and GE diffusion-weighted image data are decoded from private tags (e.g. from (0019,100e)) to the private tag (0021,1013). The format of the gradient string is as follows: B\x1 y1 z1\x2 y2 z2\x3 y3 z3\....
Usage¶
Connect input data to the module. The gradient information is automatically stored to the tag (0021,1013). For example, you can read it via DicomTagViewer or via DTIInfo.
Details¶
Use this module always before the DTIInfo module.
Tips¶
If using the SubImage to crop the t-dimension, the corresponding gradient information is not cropped. Furthermore, if using the DTIInfo, the number of excitations will also show the original number before cropping.

Input Fields¶
input0¶
- name: input0, type: Image¶
The input image.
Output Fields¶
output0¶
- name: output0, type: Image¶
The output image where private DICOM tags are encoded.
Parameter Fields¶
Visible Fields¶
Offset Last Time Point¶
- name: offsetLastTimePoint, type: Integer, default: 0¶
Number defines how many gradients shall be removed from the end of the gradient table. This option might be useful for some Philips sequences where at the end additional B0 images or unweighted images are stored.
Ignore (0021,1013)¶
- name: ignore00211013, type: Bool, default: FALSE¶
if true, tag
(0021,1013)is not checked for already encoded gradients and, thus, is overwritten.
No preceding B0¶
- name: noPrecedingB0, type: Bool, default: FALSE¶
if true, it is assumed that no preceding B0 image is available within the Siemens data set
