# Quick Start

> Get up and running with ALTICIAN Spine in 5 minutes

## Step 1: Open the App

Navigate to [spine.altician.com](https://spine.altician.com) in Google Chrome (recommended).

## Step 2: Load Data

You have two options:

* **Demo mode**: Click **"Try with a DEMO scan"** to instantly load a sample spine MRI.
* **Your own files**: Click the **Open** button or drag-and-drop a DICOM folder onto the viewport.

## Step 3: Navigate the 3D Volume

Once loaded, interact with the 3D volume using your mouse:

| Action | Mouse Control      |
| ------ | ------------------ |
| Rotate | Left-click + drag  |
| Pan    | Right-click + drag |
| Zoom   | Scroll wheel       |

Use the camera preset buttons (**SAG**, **COR**, **AX**, **Lt.OBL**, **Rt.OBL**) for standard anatomical views.

## Step 4: Run AI Segmentation

1. Download and install [Spine Helper](/segmentation/helper-setup).
2. In the right panel under **Meshes**, click **Run**.
3. Wait for segmentation to complete — vertebrae, discs, and spinal canal will appear as 3D meshes.

## Step 5: Export

Click the **Export** button to save slice sequences as MP4, WebP, PNG, or JPG.
