Overview
ALTICIAN Spine supports CT DICOM files using the same drag-and-drop workflow you already use for MRI. No additional setup is required.Opening CT Files
Drag your CT DICOM folder (or individual.dcm files) into the app window. The volume loads automatically and displays in the 3D viewer.
CT and MRI files use the same loading workflow. If you have both, load them separately and switch between sessions as needed.
Automatic Bone Mesh Generation
When a CT series is loaded, the app can generate a 3D mesh of bony structures automatically.- A threshold slider in the right panel lets you adjust which density levels are included in the mesh.
- Raising the threshold shows only dense bone; lowering it includes surrounding tissue.
- The mesh updates in real time as you move the slider.
Metal Detection
Implants, screws, and other metallic hardware are identified automatically and separated from the bone mesh.| What you see | What it means |
|---|---|
| Separate mesh layer labeled “Metal” | Hardware detected and isolated |
| Amber highlight in the panel | One or more metal objects found |
Window / Level Presets
CT images are commonly viewed with specific brightness and contrast settings. Use the Preset dropdown in the toolbar to switch between standard display modes:| Preset | Best for |
|---|---|
| Bone | Bony anatomy and hardware |
| Soft Tissue | Muscles, discs, and nerves |
| Lung | Thoracic cavity and airways |
| Abdomen | Abdominal organs |
Differences from MRI
| Feature | MRI | CT |
|---|---|---|
| Bone mesh auto-generation | Via AI segmentation (Helper) | Automatic via threshold |
| Metal detection | Not available | Automatic |
| Window presets | MRI-specific | CT-standard (Bone, Soft Tissue, etc.) |
| Segmentation labels | Vertebrae, discs, cord | Bone, Metal |
| Color appearance | Soft-tissue contrast | High bone contrast |
