Modes & Settings

Switching Between Modes

LeaRes’s dual-mode system lets you move between the medical and engineering workflows using a single toggle.

The mode toggle

The mode toggle (#panel-mode-toggle) sits at the top of the Projects and Patients window — not in the top toolbar. It is a single icon button, not a dropdown.

  • While in medical mode, its tooltip reads “Switch to engineering projects”. Clicking it moves you to the engineering workflow.
  • While in engineering mode, its tooltip reads “Switch to medical records”. Clicking it returns you to the medical workflow.

The toggle appears only if your account has access to both patients and projects.

What changes after switching

  • The ActionsTree updates to show the appropriate hierarchy (patients vs. projects).
  • The toolbar adjusts to display the tools relevant to the active mode.

Note: Switching modes changes which workflow you are working in; it does not delete data. The bridge between the two worlds is explicit — for example, a segmented anatomy can be turned into an engineering project via Store selection as project in the Segment and Reconstruct panel.

Settings Panel

Open Settings with the gear icon in the toolbar (tooltip Configure settings); click it again to close. The panel is made of collapsible sections — opening one closes the others. At the top, the cart icon opens the Recharging Station (see Account, Tiers, and Credits).

Settings panel

Account

  • Name, Email, Company — your account details, read-only.
  • Modules — the modules enabled on your account: the badge shows the first one and how many more (+11). Click it for the full list, grouped by area. Modules are granted by an administrator or bought from the Recharging Station.
  • Language — English, Deutsch, Français, Italiano, 日本語, 简体中文, Українська, 한국어.
  • Timezone — the time zone used to show dates and times.
  • Theme — see Theme Customization below.
  • Sound Notifications — turns the notification sounds on or off.
  • Guided Tour — shows the guided tour after each login. Ticking it again restarts the tour from the beginning.

System Resources

Usage bars for CPU, Memory and Disk (used, free and total), plus GPU and VRAM when the machine has a GPU. The figures refresh every 30 seconds.

Third parties

Appears only when your account is linked to an external CAD service. It shows the stored key and a button to log out from that service, which removes the key.

Data Management

For every user:

  • Export My Data — downloads your account data, patients and projects.
  • Export Medical Files — downloads a ZIP of your 3D scan data and metadata. It can be very large if you have many CT scans.
  • Export De-identified Data — the same kind of ZIP, with patient-identifying information removed.
  • Delete My Account — permanent. You must type your email to confirm before Permanently Delete Account becomes active; you are then logged out.

For administrators only:

  • PACS Servers → Manage PACS servers — the servers used to import studies (see Importing Studies from the Hospital PACS).
  • Databases → Manage databases — create, rename and delete the data databases of the installation (on installations that allow it). A database that still holds patients or projects cannot be deleted.

2FA

Two-factor authentication with an authenticator app. The section header shows whether it is Enabled or Disabled.

To enable it:

  1. Click Set up 2-Factor Authenticator
  2. Scan the QR code with your authenticator app (Google Authenticator, Authy, …), or type the Manual entry key (Copy puts it on the clipboard)
  3. Enter the 6-digit code under Enter the 6-digit code from your app and click Verify and Activate
  4. Your Backup Codes appear once: click Download backup codes, keep them safe, then I’ve saved my codes

Each backup code works once and lets you sign in if you lose your authenticator. While 2FA is on, the section shows how many backup codes remain; Regenerate backup codes (it asks for an authenticator code) replaces them all.

To turn it off, click Disable MFA, enter an authenticator or backup code — and your Password, if your account has one — then Confirm disable.

Note: Backup codes are shown only once, at activation or regeneration. If you lose them and your authenticator, you will need an administrator to recover the account.

Release date

The last line of the panel shows when the version you are using was built.

Theme Customization

LeaRes ships four themes. Choose one with the Theme selector in the Settings panel.

ThemeBackground
LightWhite
Dark BlueLight blue
Dark MonochromeGrey — raises perceived contrast on medical images
Darker MonochromeNear-black — maximum contrast

The two monochrome themes exist for medical image review, where a neutral background makes density differences easier to read.

Theme in the 3D Viewer

The 3D viewer adapts to your theme choice:

  • Light: lighter background, dark edges on geometry
  • Dark themes: dark background, lighter edges for contrast

Notifications

The notifications area (bell icon) surfaces system messages such as:

  • Simulation completion alerts
  • AI segmentation results
  • Long-running job status updates

Click the icon to review the notification history.

Common Navigation Patterns

Loading Patient Data

  1. Open the Projects and Patients window (shown at login) and select a database.
  2. Double-click a patient to open it.
  3. Click an event/series (e.g., PRE, POST, torso) to load it in the viewer.
  4. Open Segment and Reconstruct from the toolbar to segment and overlay anatomy.

Loading Project Geometry

  1. Select a database, then double-click a project to open it.
  2. Double-click a version (e.g., version_0) to load its geometry into the viewer.
  3. Expand Materials, Boundaries, and Simulations to work on the device.

Troubleshooting Navigation Issues

If the ActionsTree becomes unresponsive:

  1. Check the console (F12 → Console tab) for errors
  2. Refresh the page (F5) to reload the interface
  3. Clear the browser cache if issues persist

3D Viewer Blank or Frozen

If the GView doesn’t render:

  1. Verify WebGL support: visit chrome://gpu (Chrome) or about:support (Firefox)
  2. Update graphics drivers: ensure GPU drivers are current
  3. Disable browser extensions: some ad-blockers interfere with WebGL
  4. Try a different browser: test in Chrome, Firefox, or Edge

Note: Some advanced rendering features, such as Surface LIC for vector flow, require WebGL2.

Data Not Loading

If clicking items doesn’t load data:

  1. Check connectivity to the backend and database
  2. Verify you’re logged in (your session may have expired)
  3. Re-select the database in the Projects and Patients window
  4. Contact support if specific datasets fail consistently
