<div>The way I used DCMTK to read the images, I thought I was using an interface that already applied slope/intercept.</div>
<div><br>
</div>
<div>If that isn’t the case, itkDCMTKImageIO needs to be fixed. If you can supply a dataset illustrating the problem, I can work on that.</div>
<div><br>
</div>
<div>In the meantime, the only workaround I can suggest is to use the irk::DCMTKFileReader class to open the slices and recover the Slope/Intercept. You can then use ITK filters to apply them after reading in the Image.</div>

<div dir="ltr">Hi all,
<div><br>
</div>
<div><br>
<div><br>
<div>This question is mainly aimed for Kent, but maybe somebody else knows too.</div>
<div><br>
</div>
<div>I am trying to load a 4D flow dataset acquired on a Phillips system. On the Z slices first there are the anatomical slices, time sorted (68 z slices on 25 time frames = 1700), and then are the per axis velocities (again 1700 slices). </div>
<div><br>
</div>
<div>So these image has two different slope-intercept functions, one for the anatomical and another for velocity. Using itkDCMTKImageIO and itkDCMTKFileReader there is no clue on where are this values read. Checking the output with an iterator I see that the
slope and intercept are not considered at any time. </div>
<div><br>
</div>
<div>Is this something that DCMTK should do by itself? If I force it to look for it on itkDCMTKImageIO, what is the internal helper I should modify? </div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Thanks in advance for your help,</div>
<div><br>
