> Available anatomy, detector setup, simulated views, bone variations, and known limitations for the cervical spine simulation module.

## Quick reference

| Question                             | What to expect                                                                                                                   |
| ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------- |
| **Which projections are confirmed?** | AP, AP axial, oblique, and lateral cervical spine projections.                                                                   |
| **Can users try other projections?** | **Yes.** These are confirmed examples. Other projections may be possible when the simulated setup supports them.                 |
| **What anatomy is included?**        | Cranium, cervical spine, thoracic vertebrae, scapulae, clavicles, ribs 1-10, sternum, and upper lumbar spine.                    |
| **What setup is used?**              | Wall bucky workflow with an erect patient position.                                                                              |
| **What movement is included?**       | Head flexion, extension, and rotation; neck bending, tilting, and rotation; jaw opening and closing; and patient axial rotation. |
| **What bone variations exist?**      | Healthy bone version.                                                                                                            |
| **Known limitation**                 | Erect positioning only. Prone cervical spine projections are not supported.                                                      |

<Card title="Projection expectations" icon="circle-info" type="note">
  The projections listed on this page are confirmed examples for this simulation module. They do not define the full limit of what can be attempted. The simulator creates an image from the selected anatomy, patient position, joint movement, detector setup, tube position, collimation, and exposure settings, so other projections may be possible when the setup supports them.

## Imaging capabilities

| Capability          | Details                                                                                                                                                                         |

| Radiographic tube   | Full range of motion, including vertical, horizontal, tilt, and rotation. The cassette can be rotated, and collimation size is adjustable.                                      |
| Detector methods    | The detector setup uses wall bucky.                                                                                                                                             |
| Simulated exposures | Confirmed support for AP, AP axial, oblique, and lateral cervical spine projections. Additional views may be possible depending on patient range of motion and available bones. |

## Bone variations

* Healthy bone version

## Known limitations

The C-spine simulation is limited to erect patient positioning. This restricts projections that require prone positioning. For those workflows, refer to the skull simulation.
