GETTING STARTED
Your first positioning session.
Start with a library setup, then make one adjustment at a time.
Mobile controls
On narrow screens, start with Camera, Body, Tube or Part above the scene. Camera uses one finger to orbit and two fingers to pan or pinch to zoom. In Body, Tube or Part, choose a labeled axis and drag horizontally across the scene: right increases, left decreases. Swipe vertically to scroll. These movements keep the camera fixed and use the existing limits and contact checks. Type a precise value and press Enter, or use the fine −/+ buttons. Part and Side choose which controls to use; they do not load a solution. All controls opens the full panel; Back to 3D controls returns to the scene. Undo reverses one completed gesture. Scroll outside the scene in Camera mode.
Explore in Free mode
- Open the lab and wait for the skeleton. The first load includes 3D models and material textures. A desktop or laptop is currently the best starting point.
- Choose Open library. Choose an anatomical category and body part, then narrow by projection, recorded setup and side. Search can find a position or method. Read the reference notes, then select Load Free setup. The dialog closes and the camera frames the patient. A compatible current receptor is kept; otherwise the recipe selects its default.
- Select a part. Click the skeleton picker, click a bone in the room, or use the Part menu. Left, Right, and Bilateral control which side you adjust.
- Make an adjustment. Drag a dial, scroll over it, or type a numeric value. Patient and tube changes update the live bone projection.
- Review and capture. Move or resize the X-ray viewer. Capture downloads a PNG to your device. It does not save the pose.
Practice a position
- Select Student mode beside the Positionlab title. The patient starts standing near the table and the X-ray viewer is blank. Your Free-mode setup is kept for when you switch back.
- Choose a position or select Random. In the library, select Choose Student task. The exercise name stays in the title while you work. Choosing another exercise starts again beside the table.
- Position the patient and beam. Use the receptor, patient and tube controls. In Practice, changing the receptor leaves the patient in place.
- Select ☢ Expose. The viewer shows a frozen image. Moving the patient or beam afterward does not change that image; select Re-expose to take another.
- Select Solution. A library reference image appears beside your latest exposure with an image-match score. Re-exposing clears the old comparison so you can try again.
- Select Criteria. Review anatomy coverage, alignment, central ray, collimation and the source notes for this exercise. Reset patient restarts the same exercise with an empty viewer.
The score compares bone-image overlap with the library pose, including alignment and brightness. It is a provisional image-similarity score, not a clinical grade. Library poses and method-specific criteria still need educator validation. Practice images use a neutral display; appearance settings do not change the score. Practice attempts last for the current session and are cleared when leaving Student mode.
Keep these controls close
| Action | Control |
|---|---|
| Tabletop | Click and drag an exposed area of the tabletop to slide it in any horizontal direction. A patient lying on the table moves with it; the pedestal stays in place. |
| Wall Bucky | Click and drag the receptor panel up or down. In Wall Bucky mode, the tube and receptor follow together; use the Vertical dial for fine adjustment. |
| Look around | Drag in empty room space to orbit; scroll to zoom. Fit patient brings the skeleton back into view. |
| Fine adjustment | Hold Shift while adjusting a dial. Arrow keys adjust a focused dial; its numeric field accepts a typed value. |
| Move the whole patient | Turn on Move body to drag the red cross beside the right foot across the floor. Shift-drag raises or lowers the patient. Rotate body shows a red ring for turning. The symbol stays flat at foot height, and Part reads Body with no bones highlighted. Use the dials for fine adjustment; click the active body button again to return to part controls. |
| Adjust the pelvis | Select Sacrum & Pelvis for pelvic tilt, left/right hip hike, and sit up/down at the hips. |
| Adjust the beam | Choose Move, Rotate, or Collimate under X-ray tube. Use Center to target the selected part. Cycle Laser through Cross, 5 dots, 1 dot, Box, Vertical curtain, Horizontal curtain, Cross curtain, and Off. Curtain modes show filled alignment sheets from the tube. |
| Label the setup | Double-click Current Position or press F2. Enter confirms; Escape cancels. Geometry changes clear the label. Labels are session-only. |
| Recover the view | Fit patient changes the camera. Reset patient changes the patient pose. These are different actions. |
In Free mode, changing the receptor loads its default setup. Loading another library position replaces the current setup. There is currently no undo history or saved-pose library.
Position shortcuts and navigation order
Open the library, browse the category and body-part folders in the sidebar, then select a record and assign a number from 1–9. Assigning replaces that key’s previous record. Outside text editing and dialogs, press the number to load its setup in Free mode or select its unsolved task in Student mode. Keys start unassigned.
Open Shortcuts & order in the library to review or clear assignments, choose AP/PA and left/right order, or move categories in the V cycle up or down. Only checked, available views participate in V; save a custom view before including it. Order changes navigation, never the patient’s anatomical side. These preferences save in this browser immediately; Reset navigation preferences clears number assignments and restores order, while preserving your existing V inclusion checkboxes and custom views.
Browsing filters does not move the patient. Free loading keeps a compatible receptor or uses the record’s existing default; a saved local correction takes precedence. A setup rejected by contact leaves your current setup intact. Catalog starters and method notes still require educator review.
Take the control tour
Once the lab loads, choose Tutorial for a six-step tour of the camera, tube, whole-body, part, selection and view controls. Narrow screens add a seventh step explaining the mobile selector and gestures. Use Back and Next, then Finish; Skip or Escape closes the tour at any time. Choose Tutorial again to replay it. The tour preserves your setup and restores panels it opens.
Quick angles and patient views
Patient View frames the patient; Room View frames the equipment. Open Views for direct camera buttons. Check the views you want included when you tap V; unchecked views remain available by clicking their buttons. Save a custom view before checking it. Cycle choices are saved in this browser. Adjust the camera, right-click a Custom View button and choose Save View. Click that button to recall the perspective and zoom. Right-click and choose Rename to change its name. Keyboard users can press Shift+F10 to open the menu. Three custom views are saved in this browser.
In Free mode, the position name stays visible while you adjust the setup. A red frame means there are unsaved changes. Click the save icon at the top right of the name to save the current patient and equipment setup in this browser; the frame clears after a successful save. Reopening that library position loads your saved setup. Undoing back to the saved setup also clears the frame. Camera changes do not mark the position as unsaved.
The Receptor menu includes seated and recumbent tabletop and cross-table setups. For recumbent and wall-Bucky setups, enter Body Obliquity. The readout describes the patient relative to the receptor; wall Bucky uses AP/PA. Seated setups hide these controls. Undo and redo beside Controls restore patient and equipment together, including presets and resets. One continuous drag is one step. Ctrl/Cmd+Z and Ctrl/Cmd+Shift+Z work outside text editing.
Use WASDQE for patient positioning and arrow keys for the tube. Keyboard adjustments default to 15° rotation or 6 inches of translation; holding a key repeats the same increment. Each accepted change can be undone in one step. A step can stop early at a joint limit or patient, equipment or floor contact; reverse the step to move away. Whole Body translation carries the tabletop and patient together when recumbent, and moves the patient along floor axes when standing. Continue using dials and typed values for fine adjustments. Collimation keeps its percentage controls.
Tube controls: tap Ctrl alone to toggle Move/Rotate. In Move, Left/Right moves along Y, Up/Down along Z, and Shift + Up/Down along X. Tap Shift alone to return to the table X detent. In Rotate, Left/Right controls Tilt and Up/Down controls Swivel. Tilt follows the swivel direction. Tap V to cycle views and / for Tube View; V exits Tube View to the next view. Equipment movement keeps the room camera fixed.
The main toolbar’s AP/PA Views and Lateral Views buttons move the room camera. AP/PA alternates anterior and posterior views; LAT starts at the patient’s left and alternates sides. Views blocked by the table or wall receptor are skipped. Supine uses AP, prone uses PA, and lateral recumbent patients have both AP/PA views plus the exposed lateral side. Seated patients have all four views.
In Student mode, enter optional kVp and mAs values in the X-ray viewer. Positive decimal values are supported. Each exposure retains the technique entered when it was taken; re-expose to record changes. Selecting another exercise clears the fields. Technique entries are recorded for practice and do not change the simulated image or positioning score.
Arrange your workspace
Choose Workspace in the header to show or hide Patient controls, Tube controls and the X-ray viewer. Show & expand recovers a hidden or minimized panel. Settings remains available in the header.
On desktop, enable Float patient controls to move that panel away from the sidebar. Drag panel titles to move them; focus a title and use arrow keys for keyboard movement. Corner handles resize with pointer or arrow keys. The docked patient panel also retains its width handle. Resize affects the window only; images keep their proportions.
Choose Save workspace to retain visibility, minimization, floating placement, panel sizes and Settings placement in this browser. Restore defaults previews the original workspace; save afterward to keep it. Layout changes leave the patient, equipment, camera and current task untouched. On narrow screens, panels stack and scroll; desktop placements are retained for return. The tutorial temporarily reveals hidden controls and restores them when closed.
Save and load a session
Every visit starts with a fresh setup. In the top-right Main toolbar, select the disk icon between Mode and Settings, then Save session or Load session. One saved session is kept in this browser for the current account (or for guests); saving again replaces it. Loading restores positioning, equipment, camera and workspace layout. Student answers, scores and captured images are not restored. Saved sessions do not follow you to another browser or device.
Make the workspace comfortable
The compact Settings window has Display adjustments, Sensitivity, Colors, Lighting, and Interface theme. Changes preview immediately. Open a heading to expand its controls; opening another collapses the previous category. Use Back to return to the Settings categories. Click Save and close at the bottom to retain the open category’s settings and close Settings after a successful save. With all categories collapsed, Save and Revert to default apply to all settings.
Equipment and skeleton colors can be adjusted while retaining the selected material’s texture detail. Revert to default affects the open category; save afterward if you want to keep the defaults.
Lighting includes Lit floor area, Fade into darkness, and Projector light beam. The floor stays dark at its outer edge throughout the slider ranges. The projector brightness and color are independent of the red lasers. Choose a color preset or a custom beam color. Starting light levels are Ambient 63%, Overhead 63%, Fill 34%, Rim 0%, and Wall wash 69%; the tube does not cast shadows.
Interface theme offers Classic blue, Midnight, Sage, Plum, and Warm sand for the windows and controls. Bone Texture is the default skeleton finish; Colors → Skeleton lets you choose another finish. Use the minus button on the patient controls or X-ray tube controls to minimize that panel; use its remaining restore button to reopen it. Minimize the X-ray viewer to dock it in a small box at the lower right; click the box to restore its previous size and position.
Use the red Give Feedback button beside the mode dropdown to describe an error and include your name in the message. Feedback is saved privately for review. Include the mode, steps, expected result and actual result; do not include patient information. No screenshot or setup is attached automatically. The form keeps your text if saving fails or you close and reopen it in the same tab; reloading discards an unsent draft. See privacy details before sending.

CURRENT DEMO SCOPE
Use the preview with context.
- Educational exploration. This is not a diagnostic image system, treatment tool, patient-care planning tool, or substitute for qualified instruction.
- Bone-only imaging. Soft tissue, organs, scatter, exposure calibration, and validated clinical image quality are not included.
- Provisional articulation. Joint motion and equipment contact are geometric approximations. Patient movement checks bone meshes against each other, equipment and the floor; moving equipment is checked against the patient too. Equipment uses conservative solid bounds. Existing mesh overlaps may separate but cannot deepen under the contact guard. This is a sampled geometric guard, not soft-tissue physics. Presets load instantaneously.
- Library starters. Loading a named method does not establish exact clinical reproduction. Review the entry’s notes and verification caveats and fine-position against an authorized, reliable reference.
- Review pending. Qualified educator signoff, learning-outcome evaluation, and a complete browser/device acceptance matrix are not complete.
- Phone support is still in development. The lab may be slow or difficult to use on small screens. This guide and the product pages are designed for smaller screens.
Do not enter patient identifiers or use real patient information in position names or support reports.
