Welcome to litevna! This system was built to experiment with building a
DICOM archive using modern edge infrastructure. A subset of DICOMweb
features are supported, in order to test basic image storage and viewing
capabilities.
DISCLAIMER
EXPERIMENTAL USE ONLY. This system has not been evaluated for HIPAA
compliance and makes no formal security or privacy guarantees. Use with
de-identified data only. Upload of PHI or identifiable patient data is at
your own risk.
Features
Edge native, built with Cloudflare edge technologies: Workers,
R2, D1 sqlite database Turso sqlite database, Cloudflare caching/CDN
On demand compute - no persistent server
Javascript workers environment (WinterTC), SQLite, S3 compatible
object storage
Compute, data, and database are globally distributed (Could use
D1 when it's out of beta if db size constraints are acceptable, otherwise
can distribute read replicas with Turso), for low latency worldwide
HTJ2K image compression for fast progressive image loading
DICOMweb interface
Download images as DICOM Part 10 files with HTJ2K transfer syntax
TODO/Limitations
Have not looked at RTSTRUCT or DICOMSR support yet DONEWSI probably too big for edge infra at this time
Once D1 is out of beta, should support dynamically creating databases.
Then can add support for creating arbitrary individual archives. DONED1 beta database size limited to 2GB, will increase in GA Moved
to Turso for unlimited sizeWorkers individual request body size limited to 100MB (non-enterprise
plan)
Worker memory limited to 128MB
