Automated Medical Image Backup and Compression Pipeline

Create a robust Bash script for managing DICOM medical imaging files with automated backup, compression, and archival processes. The script must: 1) Detect and process DICOM files from multiple medical imaging sources, 2) Implement lossless compression algorithms specific to medical imaging, 3) Create encrypted backups with versioning, 4) Generate comprehensive metadata logs, 5) Integrate with existing PACS (Picture Archiving and Communication System) infrastructure. Include mechanisms for handling large image files and ensuring no data loss during compression.
