# Simulator Reference

> Use this reference to check what the X-ray Simulator supports in v1.9.0.

Use this section to check what is included in the X-ray Simulator before planning a class, lab, or student assignment.

The reference is versioned because simulator content changes over time. These pages describe **v1.9.0**.

<CardGroup cols={2}>
  <Card title="Browse by region" icon="list" href="/Simulation-Catalog/v1.9.0/browse-by-region">
    Compare simulations by region, confirmed projections, setup, movement, anatomy, and known limitations.
  </Card>

  <Card title="Global capabilities" icon="sliders" href="/Simulation-Catalog/v1.9.0/capabilities">
    Check simulator-wide behavior for patient positioning, tube movement, detector setup, control room tools, and exposure response.

## What the module pages include

* Confirmed projection examples
* Included anatomy
* Detector setup
* Patient and joint movement
* Bone variations
* Example exposure
* Known limitations

## Projection expectations

The listed projections are confirmed examples. 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.
