Getting Started with FreeDiams: Setup, Tips, and Best PracticesFreeDiams is an open-source dental imaging and management platform designed primarily for dental professionals, researchers, and students who need a flexible, cost-free solution for handling DICOM images, patient records, and clinical workflows. This guide walks you through installation, initial setup, practical tips for daily use, troubleshooting, and best practices for security and data management.
What FreeDiams Does (Quick Overview)
FreeDiams provides tools for:
- Viewing and annotating dental DICOM images (CBCT, periapical, panoramic).
- Managing patient records and clinical metadata.
- Exporting and importing images in standard formats (DICOM, JPEG, PNG).
- Integrating with imaging devices and other health IT systems via standard protocols.
Before You Install — Requirements & Planning
System requirements may vary by version; check the project’s release notes for specifics. Typical baseline requirements:
- Operating system: Linux (preferred for servers), Windows, or macOS for client use.
- CPU: Multi-core processor recommended.
- RAM: Minimum 4 GB (8+ GB recommended for handling large CBCT volumes).
- Storage: SSD recommended; plan for several GBs to TBs depending on image retention policies.
- Database: PostgreSQL or another supported RDBMS.
- Network: Reliable local network for multi-client setups; stable internet if using cloud services or remote backups.
Planning tips:
- Decide whether FreeDiams will run on a local workstation, office server, or cloud VM.
- Determine backup and retention policies compliant with local regulations (e.g., HIPAA in the US, GDPR in Europe).
- If integrating with other systems, list required interfaces (DICOM C-STORE, HL7).
Installation — Step-by-Step (Typical Linux Server)
Below is a generalized installation flow. Replace package names and commands according to your distribution and FreeDiams version documentation.
-
Prepare the server
sudo apt update sudo apt upgrade -y sudo apt install -y build-essential git curl wget -
Install and configure PostgreSQL
sudo apt install -y postgresql postgresql-contrib sudo -u postgres createuser freediam_user sudo -u postgres createdb freediam_db -O freediam_user # Set password and tune pg_hba.conf/pg_ident.conf as needed -
Install required dependencies (example: Python + libraries or Java runtime)
sudo apt install -y python3 python3-venv python3-pip python3 -m venv /opt/freediams/venv source /opt/freediams/venv/bin/activate pip install -r requirements.txt -
Clone the FreeDiams repository and configure
git clone https://github.com/freediams/freediams.git /opt/freediams cd /opt/freediams cp config_example.yml config.yml # Edit config.yml to set DB credentials, storage paths, and network ports -
Initialize the database and start the application
python manage.py migrate python manage.py createsuperuser systemctl start freediam.service systemctl enable freediam.service -
Configure firewall and reverse proxy (optional, for HTTPS)
sudo apt install -y nginx # Configure nginx site to proxy_pass to FreeDiams app, enable SSL with Certbot
Initial Setup & Configuration
- Create admin and clinician user accounts; assign roles and permissions.
- Configure DICOM AE Titles, ports, and storage paths for image ingestion.
- Set image compression and storage options (lossless preferred for diagnostic images).
- Configure automatic backups: database dumps + image store snapshots.
- Set up audit logging: record user access, image exports, and configuration changes.
Daily Workflow Tips
- Use standardized patient identifiers and consistent naming to avoid duplicates. Consider implementing an internal MRN format.
- Train staff on importing DICOM series correctly (check modality, study date, and patient name before import).
- Use templated reports and annotation presets to speed up routine documentation.
- For CBCTs, predefine volume rendering presets to ensure consistent visualization across cases.
Performance & Storage Optimization
- Store older exams in compressed archives and keep only recent or active cases on fast storage.
- Enable database vacuuming/maintenance tasks regularly for PostgreSQL.
- Use a separate disk or NAS for image storage to avoid I/O contention with the OS and DB.
- Consider a thin-client setup where heavy image processing happens on a workstation with a GPU.
Security & Compliance
- Use HTTPS for all web interfaces; obtain certificates from a trusted CA.
- Enforce strong passwords and two-factor authentication for clinician accounts if supported.
- Limit DICOM and admin ports to trusted network segments and use VPN for remote access.
- Regularly apply OS and application security updates.
- Maintain audit logs and backup copies compliant with local retention laws.
Backup & Disaster Recovery
- Implement daily incremental database backups and weekly full backups.
- Back up image store separately; validate restores periodically.
- Keep at least one off-site backup or cloud replica.
- Test a full restore procedure at least annually.
Troubleshooting Common Problems
- Images not appearing after DICOM send: verify AE Title, port, firewall rules, and check FreeDiams DICOM listener logs.
- Slow image loading: check disk I/O, database performance, and whether on-the-fly image processing is enabled.
- Permissions errors accessing image files: verify file ownership and webserver user groups.
Advanced Tips & Integrations
- Integrate with practice management software using HL7 for scheduling and billing if supported.
- Use DICOM query/retrieve (C-FIND/C-MOVE) to pull studies from PACS systems.
- For AI workflows, configure export hooks to send anonymized datasets to analysis services.
- Automate routine tasks with scripts (e.g., nightly DICOM purges, anonymization jobs, or report generation).
Community & Support
- Join the FreeDiams user forums or mailing lists for updates, community plugins, and troubleshooting help.
- Contribute bug reports and code via the project’s issue tracker and pull requests.
- Review release notes before upgrades and test new versions in a staging environment.
