Hi Tat,

Dear jcfr,

I'm sorry not to be clear, I'm using C++ and because the image scan from MRI has a bit different angle, and I recognize that the bounding box doesn't rotate with the slices. that's why I want to rotate the bounding box as same as the slices. (Note, in order to rotate as the data i got, I use the SetIJKToRASMatrix)

Did you try to click on the "fit-to-data" button as illustrated in the screenshot ? If that work, you would have to trigger the same action from cpp.

Dear jcfr,
I have already tried "fit-to-data" but it doesn't get what I want. as I have attach a screenshot(there is some bug in my computer, I will upload the image in a minute), you can see that the box doesn't warped completely around the image data. My goal at this moment is make the bounding box fit the data. (Note: not the the data fit the bounding box)

Hi,

Would it be possible to provide an annotated screenshot illustrating what you mean by "box doesn't warped completely around the image data" ?

Thanks
Jc

Dear jcfr,

As you can see in the explanation.png image, no matter what I try to do, it keep letting empty space there. What I want is the bounding box to fit with all three slices perfectly, which means the bounding box must be rotated and scaled to fit the box

Sincerely,

Tat Manh Nguyen

Within Slicer, an axis aligned minimum bounding box [1], it seems what you would like is Arbitrarily oriented minimum bounding box [2]

If this is the case, I suggest you close this issue and create a feature request that we would target for Slicer 4.4.

The VTK class internally used (vtkBoundingBox) implement a 3D axis aligned bounding box [3], it means this class would have to be extended to propose an option allowing to do non-aligned bounding box.

If you would like to contribute a patch to the VTK library, you could look at [4] for more details.

In your case, you could probably try to apply a transform to your data to align them ?

Thank you jcfr,

I understand now, and i will close this issue.
