<div dir="ltr"><div>I'm not aware of any standard DICOM tags that identify locator images. That's why I check the ImageOrientationPatient, and if it doesn't match the rest of the series, I sort the image into a different stack.

there is one locator image and because of that i had two stacks.<br>
In those circumstances i just load the stack with largest number of<br>
dedicated files.<br>
Is there some other, more elegant, solution to identify the purposes of<br>
stacks ? Via some DICOM tag for example.<br>
<br>
So for those cases i have some temporary solution.<br>
<br>
I have problem with some cases where loaded image have one slice and where<br>
series have one stack and no time slots.<br>
<br>
How should i identify those proposed situations ? To go throught files using<br>
fileindex array and compare if those values (ImageOrientationPatient,<br>
ImagePositionPatient vs. InstanceNumber) is changing in files?<br>
<br>
If so what would be solution ?<br>
