The 3D reconstruction of large data sets (in this case 287 CT Slices, 512*512 Voxels, Slice Thickness 1.5 mm, 16 bit unsigned) is not possible with 3D Image Reconstructor (Part of the Biomedical Workbench). The maximum number of CT Slices I could load is 80. I f I try to load more than 80 Slices, 3D Image Reconstructor stops with a memory error (loadmemoryerror.png).As you could see in "loadmemoryerror.png" the grayscale values of the DICOM image are also misinterpreted! After I have loaded 50 slices and try to add Isosurface Plot 3D Image Reconstructor also stops with an error (error.png).With LabVIEW and Vision tools I have developed a software (Maluna) for analysis of our Lung CT images (maluna.png). With the BMT VIs I wanted to add 3D capabilities to Maluna, but unfortunately it dont work.May be its possible to work with 3rd party libraries in LabVIEW? A very cool free Open Source software is 3DimViewer (3dimviewer.png). It loads the 287 CT slices in about several seconds and creates a very impressive 3D reconstruction of all the slices! Its really great! How is it possible that the 3DimViewer (or also other open source tools like Inversalius) could so fast reconstruct the 3D data from more than 250 2D slices?Maybe the creation of the 3D Dataset is also processed with OpenGL directly on the GPU?3DimViewer is also based on 3rd party libraries. i.e.:- DCMTk Toolkit: Very huge Open Source Dicom library (C++) with tons of functions. http://dicom.offis.de/dcmtk- OpenMesh. http://www.openmesh.org- The OpenGL Extension Wrangler Library. http://glew.sourceforge.netDoes anyone has experiences in the integration of C ++ source code like DCMTk Toolkit in LabVIEW?Best regardsPete

You can try the" 3D Vision Advanced Toolkit For LabVIEW ", which has functions similar to Medicine Toolkit, and supports 64bit LabVIEW, which expands the use of memory.
