Online DICOM viewer

Go to the ’CT’ tab and click ‘Open DICOMs’. This option loads all DICOM volumes from a selected folder, including its sub-folders. After you choose the folder that contains your scans, MeshInspector will enable you to automatically import the full dataset and prepare it for viewing.

In the file browser, navigate to the directory that contains your DICOM study. As shown, simply select the folder with all the DICOM slices inside (in this case, 427 items). Our program will read the entire folder, so there is no need to pick anything. Confirm the selection to load the full volume.

To resize a DICOM volume, first select the desired object in the Scene Tree. Then go to the ’Transform’ panel in the lower-left corner. Use the Scale field to increase or decrease the size of the voxel object. After entering the needed value, apply the transformation by clicking the checkmark icon. The volume updates immediately, and its bounding box and voxel-dimension values are recalculated accordingly.

ISO defines which intensity values inside a DICOM become visible as a surface. Adjusting this is essential for viewing. It changes how clearly different anatomical structures appear on the screen. Lower ISO values reveal softer tissues, while higher values emphasize denser regions such as bones. To modify the ISO, select the DICOM volume in the Scene Tree. Then go to the CT tab and click ‘Change ISO.’

When you open ‘Change ISO’, MeshInspector displays the voxel intensity histogram together with the current ISO-value. This value determines which density level forms the visible surface of your voxel object. Type a new ISO-value directly into the input field or adjust it by dragging the vertical marker. At the top, you can also choose between ‘Dual Marching Cubes’ and the standard Marching Cubes algorithm. Enabling the checkbox often produces cleaner and more stable surfaces around complex features. Turning it off switches to the regular method, which may render faster but can show more issues.

Voxel slices allow you to examine your DICOM volume one layer at a time, revealing the internal anatomy that may be hidden in the 3D view. As shown, the Voxel Slice panel lets you cut through the scan along the YZ, ZX, or XY planes. Use the +/– buttons to move the slice forward or backward through the volume. Also, you can enter values manually or drag them. The corresponding 2D slice is displayed in the Slice window beneath . You can also enable ’Show Inactive Voxels’ and ’Highlight Current Voxel’ to better understand how the slice interacts with the full dataset. The radius of your marker is also under control.

Under the CT tab, click ‘Voxels Line Graph’ to analyze voxel intensity values along any user-defined line in your DICOM volume. In this case, the MeshInspector program will display a graph showing how voxel values change along that line, helping you identify density variations, boundaries, and transitions inside scans.

The graph panel appears on the right side of the UI. Here you can examine how voxel intensity changes along a specific axis. X, Y, or Z can be selected to define the direction of the probe line through your volume. Then adjust the numeric value next to the chosen axis to shift the line’s position. As you move the line, the graph below updates instantly.
