  The new regions include:

  * **Bony Thorax (+ Sternum)**
  * **Cervical Spine (C-Spine)**
  * **Thoracic Spine (T-Spine)**
  * **Lumbar Spine (L-Spine)**
  * **Skull**

  ## Core Improvements

  ### Desktop X-ray Simulator

  * **Redesigned Region Selection**:
    ```
    Region -> Exam -> Simulation
    ```
    This update simplifies navigation and aligns with the categorization used in most RadTech positioning books.

  * **Control Panel Overhaul**:
    * Cleaner layout with more intuitive grouping.
    * The new **View Controls** panel allows you to toggle "collimation mode" via the grid-icon UI.
    * The Technique panel now shows an **estimate of the collimation cut-off size**.
    * Tube positioning controls now show an estimate of SID based on tube position and angle.

  * **New Functionalities**:
    * Users can now toggle skin visibility on the patient model.
    * Users can now adjust bed height via a slider for improved positioning practice.

  * **Patient Movement**:
    * The patient can now be translated either in the horizontal plane (for standing) or the frontal plane (for supine).

  ## VR X-ray Simulator

  * **New Patient Gizmo**:
    A virtual tool has been introduced to grab and reposition the patient.
    Grab and drag the control gizmo to reposition the patient.

  * **UI Enhancements**:
    * Users can now grab the plate from all sides.
    * Estimated collimator size and SID are now visible in the tube display.
