@jcfr @pieper @lassoan @superlib Good Morning. I’m starting to think about how to deploy SlicerQR to 25,000 PCs across the Mayo Enterprise. After building the package, it consists of over 7000 files at a total size of over 700MB. It would be seriously frowned-upon to propose deploying it to 25,000 …

@lassoan @pieper @jcfr @Sankhesh_Jhaveri Question: Do any of you know my friend, Hunter Downs?

Question: Do you all do anything with A.I. in imaging?

[image] Slicer custom application deployment to many computers might I be able to get the size down significantly smaller than 300MB? Sankhesh’s 2018 FourPanesViewer app was has a total size of 60MB and had similar functionality. The FourPanesViewer is pure VTK. It has no GUI widgets, no prope…

Thanks @lassoan , I know I’m flooding you with questions here. Here’s more… What are you using for DICOM parsing. In FourPanesViewer, I am using David Gobbi’s vtkDICOM functions to parse DICOM. I think Gobbi’s objects have been integrated into VTK installations in VTK 9. I’m also using GDCM fo…

[image] spycolyf: What are you using for DICOM parsing. In FourPanesViewer, I am using David Gobbi’s vtkDICOM functions to parse DICOM. I think Gobbi’s objects have been integrated into VTK installations in VTK 9 vtkDICOM can handle basic DICOM - 3D Cartesian volumes with uniform spacing. No …

Wow, that’s great to know about vtkDICOM. I was really going in the wrong direction. Y’all saved my life. Thanks. I might be mistaking, but I’m under the impression that DCMTK does not handle JPEG 2000 compression. If so, it a recent development. Liqin wrote our QREADS DICOM receiver and is now usi…

Also, I did inform my team that the smallest size we might could possibly achieve is around 300MB. So, we will come up with a deployment scheme that will work. When I suggested the possibility of SlicerQREADS (SQR) staying up in the background once launched, the concern was what if QREADS it termina…

@lassoan @pieper @jcfr - Question: As you know, building SlicerQREADS can take hours. I know if I make changes to the Python script, I don’t have to rebuild. But do I need to perform the 3 hour rebuild if I make a small modification to the C++ code?

You only need a full build once. After you make modifications in the C++ source files and build again then only the changed files are compiled and linked, which typically takes about 15-30 seconds.

[image] spycolyf: I’m under the impression that DCMTK does not handle JPEG 2000 DCMTK tried to make some income from not bundling JPEG2000 codec with the free DCMTK version. Slicer falls back to read with GDCM if DCMTK fails to decode an image. [image] spycolyf: the concern was what if Q…
