CT & Voxels BasicsVoxel volumes in MeshInspector. Open DICOM, RAW or TIFF data or make a volume from a mesh, find the right tool of the CT tab, and follow short recipes from a CT scan to a printable mesh.
Voxels to MeshConvert a CT, MRI or other voxel volume to a mesh in MeshInspector. Pick the iso-surface with Change ISO, run Voxels to Mesh (Simple or Smart Conversion), check, repair and export the mesh.Video

Open DICOMs, Open RAW Voxels, Open Voxels From TIFFHow to open CT and other voxel data in MeshInspector with Open DICOMs, Open RAW Voxels and Open Voxels From TIFF, which also formats Open Files takes, and the RAW file name pattern.- CT ReconstructionCT Reconstruction in MeshInspector builds a voxel volume from 16-bit TIFF X-ray projections on an NVIDIA GPU. Which builds have it, input files, panel fields, result and errors.Video

Volume RenderingUse Volume Rendering in MeshInspector to show a voxel volume as a semi-transparent cloud, set the value range and opacity, cut it with a plane and pick an iso value from the section.Video
Change ISOUse Change ISO in MeshInspector to set the iso-value of a voxel volume with the field or the histogram, choose Dual or standard Marching Cubes, and prepare the surface for Voxels to Mesh.
Voxels SliceUse Voxels Slice in MeshInspector to browse a voxel volume in YZ, ZX and XY slices, read the value of any voxel, set the gray-level window and save slices as images.
Voxels Line GraphUse Voxels Line Graph in MeshInspector to plot voxel values along a line parallel to the X, Y or Z axis, find walls and material boundaries and choose an iso value for Change ISO.

Set Active Voxel BoxSet Active Voxel Box in MeshInspector limits a CT or voxel volume to a box of voxels, or crops the box into a new volume. Controls, results and how to return to the full volume.
Voxels ResamplingVoxels Resampling in MeshInspector changes the voxel size of a CT or voxel volume, for example to make the voxels cubical or to make a large scan lighter. Parameters, result and when to use it.
Voxels NormalizeVoxels Normalize in MeshInspector linearly rescales the values of one or several CT or voxel volumes to a range you set, 0 to 1 by default. Parameters, result and when to use it.
Binary OperationsBinary Operations in MeshInspector combines two voxel volumes voxel by voxel into a new volume. Requirements, the panel, and the Union, Intersection and Difference operations.

Voxels SegmentationVoxels Segmentation in MeshInspector cuts one structure out of a CT volume from seeds you draw on a slice and builds a mesh of it. Panel, mouse and keys, IO scan picking mode, result.Video
Voxels PathVoxels Path in MeshInspector finds the route between two voxels that best follows the voxel values, for example along a channel. Picking voxels, metric types, Build four and the result.
Voxels InspectorVoxels Inspector in MeshInspector shows how voxel values change across a surface and moves the vertices of a mesh onto the boundary in a CT volume with sub-voxel precision. Graphs, Adjust, color maps.
